Re: [Dovecot] Configuring mbox and maildir formats - dovecot-1.2.15

[Scott Silva]

on 10/27/2011 12:52 PM Albert E. Whale spake the following:

I am transitioning an existing server from using exclusively mbox, to being
able to support both mbox and then fully maildir formats.

I need to support the mbox format until I can get everyone switched over to
maildir.

What do I need to to use in the config of /etc/dovecot.conf to support the
default of mbox, and then the new Maildir format (users will get upgraded
individually from mbox to Maildir, and need to be upgraded).

Thank you.


When I did it, the automatic detection seemed to work OK. The only problem I 
had was because I used procmail for delivery. I had to have a custom 
procmailrc for each user as I did their migration. For each user, when you 
finish their migration, you have to rename their ~/mail folder to not show 
dupes. In my case as soon as there was a ~/Maildir folder, dovecot started 
using it and made new indexes.

on 11/21/2007 5:06 AM Marcelo Iturbe spake the following:

Hello,
I had an Inbox with 975,604 emails on ext3 filesystem.
I keept getting dropped on the comand "copy 1:2000 inbox2", the syslog gave
me an error message indicating "out of memory" problems.
This despite the fact that the server has 800MB of ram free.

Anyways, I asked if I could manuanlly move the files at the filesystem level
or if that would mess up dovecot (break the GUIDs etc).
I was informed that dovecot does not use GUIDs and that I could go ahead and
move the emails at the shell level.

So I did that, now the /cur folder only has 40,000 emails, but when I
connect to the account via telnet, I still get the following:

telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
* OK Dovecot ready.
110 login somelameuser somelamepass
110 OK Logged in.
111 select inbox
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags

* 975604 EXISTS

* OK [UIDVALIDITY 118842] UIDs valid
* OK [UIDNEXT 979500] Predicted next UID
111 OK [READ-WRITE] Select completed.

So even though there are only 40,000 emails in /cur, dovecot still thinks
that there are 9756304 emails.

How can I fix this?

Thanks

Re: [Dovecot] Embracing .99

We're stuck on RHEL 4.x, so we're currently working on a plan to live in
harmony with .99 for another year or so. With that said, the plan is
below. Let me know if you have any other recommendations.

[ ]Convert to high-performance mode vice high-security to reduce overall
resource usage.
[ ]Implement iptables throttling for new connections to prevent denials
of service.
[ ]Covert from mbox to maildir to help reduce the likelihood of
corruption that lead to mailbox outages.

As our overall individual mailbox usage is low, maildir seems to be a
good option as mbox corruption has severely impacted a few of our
high-profile applications. However, does anyone know of a sane method to
use maildir on RHEL 4.x without switching over to Postfix?

Thanks!

You are not necessarily stuck with .99. You can upgrade dovecot and you only 
lose support on Dovecot issues. You can use maildir easily with sendmail also, 
as procmail in 4x supports it. You just have to create a procmailrc in /etc 
like below;

I do see some benefit, at least for us.
We get a lot of mail from a bank, but I cannot whitelist the bank by domain, 
because of phishing. So I either have to write some custom rules and 
experiment, whitelist each individuals address as they hit, or validate their 
domainkey and bump any scores back down enough to clear the filters. I think I 
will look at enabling the dkim plugin in spamassassin and see what happens.

Hmmm.  I would have listed mx as well but thats just me.  But just
listing a is likely better in that there are less lookups for the
receiving system.

One thing that bugs me is why we must now implement domainkeys on top
of SPF.  SPF pretty much does everything domainkeys does but simpler.

Because SPF is a broken hack that doesn't properly accomodate the
forwarding of email without the use of other complicating hacks
such as SRS which mangle the sender address.

SPF should have been scrapped years ago.  Instead, most large
organizations use "?all" in their SPF entry (typically because of the
forwarding problem), putting SPF in advisory mode which negates the
whole purpose of having it anyway.

I disagree.
The only way you should be using SPF on the receiving end is as an
additional weight for spam scoring.


Some time ago there was a similar discussion on the postfix ML and I had
pretty much the same arguments that you had.

But as a matter of fact, I got corrected. The major problem with even
scoring is that the only things spammers have to do (and they really do
it!) is to register some new domain, enter valid SPF records for it and

That is why you don't score on pass, but incremental score on fails. That way 
a fail will bump the score a bit, but a pass won't negate the other hits.

Actual sendmail only lets the trusted users send mail with a different "from"

Very informative yes, but at the same time it seems to make the same mistake

described anywhere (admittedly, that I could find) what mbox is.  It took
much looking, and in fact one respondent to my question, a week ago, about

constructive criticism, I'm not trying to be condemning here.

Anybody setting up something like a mailserver should HAVE the basic knowledge 
of these things. If you don't know the basics of how e-mail works, you should 
have someone else set up your system. It is too easy to mis-configure a mail

Re: [Dovecot] Please help me resolve why mail isn't being delivered to virtual users

[Scott Silva]

on 1/11/2008 10:43 AM Andrew Falanga spake the following:

Hi everybody,

There are a few things that I think I need to explain.  Far too many people
gave me feedback after my remarks about the dovecot wiki for me to answer
all individually.  At first, I must admit to some prideful need to lash back
for not being understood.  This however, would be totally inappropriate and
completely worthless.  Now, hopefully, I can articulate my thoughts without
sounding prideful and egotistical (very hard to do without the added benefit
of inflection when talking face to face).

My original statement that sparked this lengthy thread now was really born
out of nothing more than my observation of documentation after working five
years at HP as a programmer (not as an HP employee though).  I have seen,
even from my own efforts of writing more documentation than I care to admit
to, that inevitably there are things that become so common place to the
person writing the doc that they don't even realize they are fundamental to
understanding how things work.

Unfortunately, I used as an example, mbox and MAILDIR to make my point.
Perhaps this was a bad choice because I felt this same frustration in
reading other areas of the wiki.  It wasn't that the information was bad, or
unusable.  I just had questions about how it all fit together for dovecot,
and couldn't find the answers on the dovecot site.  I don't think it's
unreasonable to ask that a particular software program explain how it's
pieces fit together, or how it (the software program) is supposed to work
with other pieces it makes use of but doesn't directly control.

Now, here comes the other problem.  I was in a crunch.  The church e-mail
system had died, and a replacement was needed ASAP.  Originally, I should
have had more than adequate time to find my answers.  Normally, I do spend
much more time trying to find the answers myself.  (At this point, I can
only ask you to believe that.)  I learned a painful lesson in this several
years ago while learning OpenBSD.  I learned that I really did expect folks
to take me by the hand and walk me through.  It's something that I've worked
hard to overcome, and sometimes still struggle with.

I'm sorry that I reverted, to some degree, to this tendency with this whole
dovecot endeavor.

I do have more than a rudimentary understanding of how mail works.  After
all, I didn't ask everyone to explain IMAP, POP or SMTP to me.  Nor did I
ask for an explanation for SSL/TLS or other things.  Further, I didn't ask
any questions here for how to make sendmail do SMTP authentication.  Coming
into this, I knew that SMTP was the MTA, things like sendmail and postfix
did this, while other programs, e.g. dovecot; allow users to login and get
mail from the server.  An interesting thing for me to ask myself is, "Why
did I look up postfix on google, but not mbox?"  I didn't know what postfix
was and did look that up on Google.  When trying to get things working, I
was assuming that mbox and maildir was something dovecot implemented itself,
not a standard of sorts that dovecot implemented from a standards outline.
That's why I thought it strange dovecot didn't define what they did.
(Perhaps even why it didn't dawn on me to Google the term.)  I must also
mention that another respondent did give me a link in the dovecot wiki to an
explanation of mbox and so on.  I missed that one when doing my research.

In short, I'm sorry that I gave the impression that I assumed dovecot
developers and documentation writers should explain every little detail to
me.  I do not think this, nor was I trying to persuade others that I did
think this way.  My remark about a disclaimer was taken to an extreme I did
not intend.  I do think disclaimers on every page is excessive is
ridiculous.

In the future, I shall endeavor to look more heavily for the answers before
posting, or at least before assuming that no one on this list is willing to
help.  Thank you to all for the help given.

Andy

worse in the morning when I wake up. Thunderbird's checks the email 
every 1 minute and it's set up to check several IMAP folders. I'm 
running the latest Thunderbird release as will as the latest Dovecot 
(not the beta versions).
Hammering the server every minute can be hard on the server. Especially if all 
the users do the same. I personally make users check no more than every 10 
minutes automatically.




In the morning it is as if it can't access dovecot at all. I get an hour 
glass as if it is waiting for something that's never going to respond. 
But if I shut down Thunderbird and restart it then everything works 
normal for a while.
I use Xp and also leave it on all the time. Sometimes Thunderbird will seem to 
run out of memor, and a restart is the only thing that will help. But in my 
case it isn't dovecot because I can still read my mail from other clients and 
other machines.




My server is doing a lot of work but the load levels are low. Running 
Fedora 8, dual core AMD 6000+ processor with 8 gigs of ram.


My experimenting with adding more authentication processes seems to help 
but I could be fooling myself. That's why I'm experimenting to try to 
figure out what's making it slow.


Trimming the accesses down from every minute should help this also.




Like someone else said, I saw something like this happen with several 
RCs but at the time I thought it was MBOX related. I'm not using Maildir.


Hope this extra info helps.

How much longer can a system be expected to run? 8+ years at 24/7 is about a

Re: [Dovecot] mbox to maildir conversion does not work

[Scott Silva]

on 2-28-2008 10:02 AM Scott Bruce spake the following:

Hello,

I have got it working using
convert_mail = mbox:~/mail:INBOX=/var/mail/%u
and it converts fine to maildir.

The one problem that I am having now is that client downloads some of
the emails again, after conversion.

Let me described the situation,
I'm trying to migrate from qpopper pop3 to dovecot pop3, which works 
with  no problems, using the 'pop3_reuse_xuidl = yes' setting. And
'mail_location = mbox:~/mail:INBOX=/var/mail/%u'. At this point no email 
is downloaded twice.


But when I go to convert the /var/mail/%u to /var/imap/%u/.imap/, using
the convert mail plugin, only the mail the has been delivered once 
before using the dovecot pop3 deamon is been sent again, not the email 
that was set using the qpopper deamon. All of the mail is being converted.


Do you know why this would be?

What it looks like I will be doing is going strait from qpopper to 
dovecot converting to maildir, but I was hoping to use dovecot with the 
mboxs as an intermittent stage.


Thank you again for your time,
Scott
You might need to set dovecot to use the qpopper UIDL format, it you can find 
what it is.

Hi people!

I just switched one of my servers from Courier to Dovecot. Planned to do it
anyway but had to do it faster after the discovery that courier [the 
version

I had installed, at least] returns malformed headers for a few messages,
causing Outlook Express to completely ignore them. Curiously, they were
visible in Squirrelmail and Nokia Series60 e-mail client.

Overal I am quite happy but have one little problem. More often than not, I
have to press 'Purge' button two or more times in order to actually remove
the deleted messages. The fragment of Outlook's IMAP log is below. 
Interestingly, Dovecot 1.0.7 (on another server) does not have such 
problem.


Are you sure that they weren't removed the first time but Outlook didn't 
refresh its header listing?


I have seen outlook take its sweet time in updating its header listings with 
IMAP. I never thought that its support for IMAP could be worse than its 
support for POP3.


I have to deal with it just because of the varied users I support, so I have 
Outlook, outlook express and thunderbird all configured to see my message 
store just for experimentations sake. But I use thunderbird daily.

P.S. For the record, the DEC box has only ever needed to be shut down 
for power outages and (in its early life) OS upgrades. It ran 24/7 and 
never had a hardware fault (and still doesn't). Now that's reliable 
hardware!

True,
but just because it hasn't failed in 13 years doesn't mean that it wont fail 
tomorrow. Or next week. Everything wears out sooner or later. I don't feel 
right using a server for critical systems for more than 5 years. I usually 
will warranty them to that age, and then move them on.


The servers that used to handle our e-mail needs a few years ago are now 
terabyte backup targets. A new raid controller and some new drives, and the 
critical part of them is as good as new. If a MB or power supply dies I can 
move the drive cage to another system and get to the data in less than an hour.

I think most mbox files would start with "From " or the UWimap header if they

I did have Usermin configured to read directly.  I have changed this so 
Usermin goes through the local IMAP server (dovecot) and Usermin seems 
to be working much better with the mail.


However, I have a new problem...

I've changed my mail location back to mbox as follows:

mail_location: mbox:~/mail/:INBOX=/var/mail/%u

This is working great with two exceptions.

First, using mozilla thunderbird as a client, I can create folders, but 
I can't create sub-folders.  Why might this be?

How are you trying to create the folders?
With mbox you have to create the folders with a trailing slash "foldername/".
You can only have either a folder or another mbox, but you can't have both.


Second, I have Usermin configured to save a copy of sent mail in a 
folder 'Sent'. mozilla thunderbird is doing this OK, but Usermin is 
not.  It gives me the following error on the web interface:






 Failed to send mail : Failed to set IMAP flags : Error in IMAP
 command UID: Invalid arguments.
I never thought usermin as a webmail client was very good anyway. It seemed as 
more of a kludge then polished software, especially when accessing mail by IMAP.






Checking through the logs, I don't see any other errors so I'm having 
trouble find out why?  The email does get delivered, but no copy is saved.






On your second question, I run bothPOP3 and IMAP on the server. Some 
people with light traffic just want to get the mail to their PC, and 
other users want IMAP so they can work with their mail from multiple 
locations and computers.


That's exactly what I'm going for.  Good to hear I can expect it to work 
fine.




I still have problems with outlook on pop3, especially if the mail is left on 
the server and also accessed with another MUA like outlook express -- don't 
ask -- stupid PHB decision -- but I haven't had other problems. I have 
Thunderbird as my MUA of choice, but also have both outlook and outlook 
express accessing my IMAP store occasionally for testing and debugging 
purposes. I'm also testing several webmail softwares on the same mail store 
and I haven't seen any gotchas.

Hello,
I saw the problem quite often in various posts but could not find a real 
solution .
Problem is that I frequently get annoying popups from outlook 2007 about imap 
idle timeouts which block working with outlook until the popup is acknowledged.

The popup says:
 Your IMAP server closed the connection. This can occur if you leave the 
connection idle for too long.
 Protocol: IMAP
 Server: testhost
 Port: 143
 Error Code: 0x800CCCDD

I tried to run dovecot with or without  "imap_client_workarounds = 
outlook-idle" but do not see any difference.
I am running dovecot on Red Hat Enterprise Linux Client release 5.1 (Tikanga).
Below is the output of some commands to get a clue about my config.

Background info:
Our primary mailboxes are on exchange servers.
As there is a size limit on the server mailboxes I am evaluating a local 
storage solution for our users.
Thus  I set up an additional mailbox in outlook using IMAP.
Local .pst files can not be backuped easily (especially when outlook is 
running) and I am investigating a local IMAP server where users can move their 
mails to. This server can easily be backuped (even incrementally when using 
Maildir) and users do  always have access to their mails.
The drawbacks are that users must have an extra login to the imap server 
because I have no ldap access to the company AD server from our local site 
domain.
The solution will not be accepted though if I can not prevent the frequent 
disconnect popups.

Peter

Current is 1.0.13, at least a year newer then the release candidate you are

My server currently uses:

Incoming: imap.example.com
Outgoing: smtp.example.com

If dovecot 'understands' smtp, then why couldn't you just point the 
outgoing to 'imap.example.com', so no Client mods would be needed?


But the clients send to port 25 on the outgoing server, unless you force them 
to use something different. Port 25 is SMTP. You can have incoming and 
outgoing on the same server, you just need a MTA running along with the

I know that the Maildir format does the sub-folders+messages, but I'm
not really interested by the one file per email.


With v1.1 you could have maildir++ directory layout with mboxes
(mbox:~/mail:LAYOUT=maildir):

~/mail/.mbox1
~/mail/.mbox1.submbox

Now you are scaring me. Fixing something even BEFORE someone asks. You are

If you want to use pop3, you might need to mark mails instead of moving them

Yes - take a look at the "expire" plugin: http://wiki.dovecot.org/Plugins

dovecot to behave like courier-imap?


That shouldn't be.  If you're using Dovecot for both POP3 and IMAP, your
mail client will be able to see all the mail no matter which protocol you
access it with.

However, your mail client may be ignoring mail that's been "Seen".  
I'm not

sure why courier would behave differently with this.

Have you read the migration guide?

Many thanks for help.

Hello,

Thank you for your email.
We have been using XMail (www.xmailserver.org) for smtp and pop3, 
courier-imap for imap. This works for many years and we don't want to 
change. The only change we would like is to switch from courier-imap to 
dovecot. So configuration must be unchange: xmail for pop3 and smtp, 
dovecot for imap.
Unfortunately we are facing the problem I wrote about: after a user 
access mail box via web client (www.squirrel.org) he can not see emails 
any more via pop3. The reason is emails moved from 'new' to 'cur' 
although nothing done. Dovecot automatically moves. Currently with 
courier-imap, no matter we access via web mail or imap client (such as 
ThunderBird or Outlook) users can retrive emails via pop3. So my 
question is: does courier-imap behave abnormally or my dovecot 
mis-configured?


Dien Phan

More than likely the pop3 client downloads the messages and then deletes them. 
That is how pop3 works.

Re: [Dovecot] Feature Request - starting dovecot, config file behavior

[Scott Silva]

on 4-18-2008 3:43 AM Charles Marcus spake the following:

Hey Timo,

I was wondering how much trouble it would be to again emulate the way 
postfix does something - in this case, the way it reads its config file 
when starting up.


Current behavior:

Postfix:
If postfix encounters the same setting defined more than once, the last 
one wins.


Dovecot:
If dovecot encounters the same setting defined more than once it gives 
an error (also when using the 'dovecot -n' command).


I like to add all of my changes to the very bottom of the config file, 
but otherwise leave the config file as is... this makes it very easy 
when updating - I can easily keep all of the new default config file, 
and simply merge my customizations at the end.


So - how hard would it be to make dovecot simply accept the last defined 
setting read, instead of refusing to start?


Thanks much, and glad to have you back in action!

That seems like a major change in function. To some admins it would be like 
suddenly having to drive your car from the other side. Maybe Timo will see it 
your way, but maybe not. And anything else that is parsing the config file 
might also get confused, like someones custom web frontend to config files.


If this major a change was added, it might be better to add it to the 2.0 tree.

There is a setting under Advanced options on the iPhone where you can
"Delete messages after XX days", but the lowest you can set it to
is "1 day".  I have no idea why there isn't an "Immediately" option.

I'm also unsure if that is actually the expunge action, or if the phone
is doing some sort of manual move to the Trash folder instead after
that period of time.

I don't think you will get dovecot to do any expunging without a plugin, 
because only the client is supposed to expunge in the IMAP spec.

You could look at the plugins info at http://wiki.dovecot.org/Plugins

Nevertheless, it would be very nice if you could fix it. It's a
fairly big availability problem (for us, at least).



The problem is not so much how dovecot deals with this issue, the
problem is, why is your server having such drastic problems keeping its
time sane?

Fix that, and your problem disappears.

  
I would just like to mention a circumstance that happened to me this 
Sunday.  We had a total power outage in our building, longer than our 
UPS's could last and we don't have a generator for servers (nor is it 
economical or needed).  When the power came back on, my local NTP server 
came on at the same time as my mail servers, as well a majority of my 
other servers.  My servers tried to step their time to be in sync with 
my local NTP server, which was still busy trying to sync itself with 
outside sources, which takes a while, so my mail servers did not get an 
answer.  Later, dovecot died because the time finally synced, and I 
found out why pretty quick (have seen this before) but this was an 
unusual situation.
My point is, we had an unusual circumstance, and even though I've taken 
steps to have my mail servers sync their time at boot and run ntpd 
afterwards, there are some circumstances in which this is not enough, 
and dovecot still died.  Its not always because someone was lazy about 
their time setup.  But it doesn't cause me "big availability problems" 
since in general, my time is fine.


This would be a good case for running ntpdate on startup at least on the ntp 
server. Just point it to a reliable outside server. AFAIR RedHat and clones do 
this in the init script for ntpd.

I have a user who's deleted an important IMAP mailbox and I'm now 
recovering a recent copy from the backup. But I'd rather just blanket 
disallow all folder deletions.


The user is using Thunderbird and this has happened more than once so I 
suspect Tbird is willing to let a folder get deleted too easily. Perhaps 
there was a delay in the confirmation dialog and the user clicked ahead 
and confirmed something he shouldn't have.


You mean thunderbird LET a user do something stupid? Even after asking" Are

You know that the people that sign your paychecks are under an

1) Higher mail limits.
2) Exemptions from the filters on the web proxy.
3) Immediate service.
4) Any other butt kissing you think necessary to keep them happy.

Sometimes it can legitimately take a while, especially for older archived stuff.

Once a VP couldn't understand why his search for a "titanium driver for his

part of "TIT"anium that triggered it. Then he was totally on board, and 
usually just e-mailed me on any sites that gave him trouble.
My bosses usually embrace technology, they just don't have a lot of experience

I checked my own mailbox using mutt and I see 11 messages that are

They stay until they are purged. There are plugins that will help if you are

logins slow to a crawl if not outright fail, esp people checking mail 
through Squirrelmail.  Things get better after a dovecot restart.  
Googling around, I thought if we switched the order or disabled the 
second passdb we had configured for our dovecotadmin account, these 
failures would go away but that did not happen.  Any thoughts or 
additional info I can provide?  Pardon the unusual install prefix. We're 
trying to keep the source install separated from the ancient dovecot rpm 
shipped in rhel5.

Re: [Dovecot] Mutually exclusive Exim setup instructions

[Scott Silva]

on 6-11-2008 4:10 PM [EMAIL PROTECTED] spake the following:

The correct way has to be one or the other:


http://wiki.dovecot.org/LDA/Exim

are mutually exclusive with

http://wiki.dovecot.org/HowTo/DebianStable

It appears that exim can either call dovecot's LDA or make the delivery
itself.  There may
be good reasons to do it one way or the other.


Sorry to be diving into this issue so late, but I just noticed this email.
 You may be able to answer a question I have.  At the moment, I use Exim
and Dovecot, and have things set up to use imapd, using Dovecot as the
LDA.  It worked fine for a while, but with upgrades I am now unable to
send email out using Thunderbird (for example - this applies to KMail and
Sylpheed as well).  Exim treats it as a relay, and bans it.  Curiously,
using these from another machine works fine.  Also fine is sending mail
internally, from a cron job for example, or to external addresses from my
website.

It seems that the router setting in Exim is the problem, and the better
solution is to use Exim as the LDA, but if one does not use Dovecot as the
LDA, what's the point of having it?  I installed it originally to be able
to use Squirrelmail when I'm on the road.  Now I'm using it all the time.

What am I missing here?

Dovecot is not just an LDA, it also serves POP3(S) and IMAP(S) services.. The 
benefit of using dovecot for the LDA is to keep the indexes and other files 
updated. I am using dovecot on CentOS, with procmail as the LDA, and 
everything still works fine.
But you can only have one LDA ( or at least should only use one), so those 
docs would be mutually exclusive.

the RPM to begin with.  Back then, I was more than capable of fixing 
things - but that was a long time ago.  So I want to proceed cautiously

That said, if upgraded is it possible to resolve this issue, or should I

very popular so I find it odd that Apple would not foresee this issue.   
So it would seem that a solution exists, but I don't have that

Is your IMAP server using mbox or maildir for the mailstore?
Maildir should be able to handle the folders.

I have a problem with the Dovecot configuration; I have my Postfix server in the host: 192.168.100.100, and I have installed Dovecot in the host: 192.168.1.253. Everything goes right, but I can't see any mail that I had received in my mailbox. 

 


How can I configure the dovecot.conf in order to use an mbox placed in a

Re: [Dovecot] dovecot.conf permissions

[Scott Silva]

on 7-24-2008 1:18 AM Dan Horák spake the following:

Hi,

I have a little problem with defining the right permissions for
dovecot.conf. The main problem is that the password for SSL certificates
is stored there and the conf file is world readable by default, which
makes a security problem [1]. It is not a problem to restrict the
permissions to 0600, dovecot will still work, but then deliver cannot
work as it reads the conf too, but it runs under arbitrary user. So my
last iteration is 0640 as permission and root:mail as ownership, but
that expects that deliver is run with group = mail. For the long term
solution I would prefer to move the password into a separate config file
so the permissions can be properly restricted there. What are your
opinions?


With regards,
Dan


[1] https://bugzilla.redhat.com/show_bug.cgi?id=436287
You can always have no passwords on ssl certs. Probably just as secure as a 
world readable password.

Re: [Dovecot] Delivery notifications

[Scott Silva]

on 7-24-2008 9:03 AM Brandon Keepers spake the following:
I'm working on an application that is backed by Postfix 2.3.8 and 
Dovecot 1.0.13, configured with virtual domains, for handling messaging.


I need to be able to send the notification (such as "You've received a 
new message on SomeAwesomeService. Click here to check it out", It's 
evil, I know) to a different email address, such as a mobile device. 
Eventually, we want to do other things like clear web page caches when a 
message is received, or sending IM notifications, but that's for another 
day.


So basically, we want to notify our application whenever a new mail is 
received, and it can do all the magical things that it needs to do.


I was hoping to get some feedback on the different approaches I'm 
looking at. From what I can tell, there's not a way to deliver to 
multiple virtual transports in postfix, so here's the options I see:


* Content filter
I could set up a "content filter" that just delivers the mail to the 
application, and then re-injects it back into postfix. This seems like 
more work than the other options just because I have to worry about 
re-injecting the message


* Intercept delivery
Replace the dovecot deliver command with a custom one that calls the 
dovecot deliver and then passes the message on to the application.  I've 
written a little proof of concept for this and it seems to work, but 
just seem shady.


* Sieve
Dovecot supports Sieve, so I could just have a global sieve script that 
sends the notifications.  This is definitely the solution I'm leaning 
towards.


Are there any better options? Do you think this will have a significant 
impact on performance? Am I crazy?


Thanks,
Brandon
In my opinion (which is worth every penny you didn't pay for it) If I want 
notices of my new messages on a phone or other mobile device, I might as well 
just get the message sent or copied there.

Re: [Dovecot] Server-side sieve for client-side copies

[Scott Silva]

on 7-28-2008 9:38 AM Daniel L. Miller spake the following:
I know I could test this - but I'd rather ask first.  To my knowledge, 
we haven't come up with a good server-side implementation for savings 
copies of sent messages (by all means correct my ignorance in this 
regard).  So the typical way is to enable it in clients like Thunderbird 
(this prompted a whole discussion of how to save these messages without 
sending them to the server multiple times).


My understanding is that sending a message from a client (use 
Thunderbird for simplicity of this conversation) is performed via SMTP.  
Saving a copy into a sent folder is performed via IMAP (hence the 
multiple transfers to the server).  Now that I've laid a background - 
let's make it Dovecot specific.  I don't know how "behind-the-scenes" 
Dovecot performs the act of saving mail messages that it receives from 
IMAP, instead of SMTP.  Specifically, if I'm using sieve filters via 
deliver - can I setup a filter that will place mail copies to specific 
recipients into specific subfolders?
Not easy, but set client to BCC yourself, and set filters for messages from 
you/to you.
Until they modify the IMAP spec, and then every mail client is updated, it 
just isn't going to be an easy fix.

Re: [Dovecot] dovecot sieve sends vacation messages with null envelope sender

[Scott Silva]

on 8-12-2008 7:26 AM CJ Keist spake the following:

Josef,
   This is exactly same situation in our environment as well. I had to
make the same change as you stated.  Our central virus/spam email
gateway also cans any message with out a valid from address in the mail
headers.  I would think most virus/spam systems will do the same.
   I understand the concept of having the from empty, namely to keep
another automated system from replying back to your vacation reply, but
what do we do to keep our vacation replies being canned by anti-spam
systems??  Maybe this should be a option in the configuration file to
let the Admin decide whether to fill in the from address field, or a
"[EMAIL PROTECTED]" default, or just empty?

IMHO if someone's e-mail is so important that you would have to notify people 
that they are on vacation, then a human should be checking their account 
everyday. A vacation message just tells me to go somewhere else, which would 
probably end up being a competitor. If I know the person, I probably already 
know they are on vacation. If I don't know them, I probably don't care.


I will let people have a vacation message, but I will tell them that they 
might not get delivered. If someone leaves, I alias their mail to their 
successor, or just delete their account.

This is nothing new... time has *always* been considered extremely

An ntp client has always been the way to go...

But you should also make sure your hardware clock is not totally crapped

During a cold start is probably the ONLY time ntpdate would be appropriate. 
Call ntpdate right after the network starts, but before the other services get

All of these prelink errors suggest that your binaries were overwritten 
from a tarball installation. The easy fix is to erase ("rpm -e") the 
package and re-install it, likely upgrading to a newer package at the 
same time.
But a rpm install will not overwrite the tarball install since tarball 
installs usually go to /usr/local or under /opt while rpm installs will go 
into /usr directly. I don't know if the tarball has a make uninstall command, 
but the previous admin "should" have left the unpacked source around from the 
install somewhere in either /root or in his home directory. That can give more 
clues.

"d" files are documentation, and if you're tight on disk space, you can

I've got an old dovecot installation (0.99.10.5) which

Now I need to decide whether to update it to a newer

One feature that I really need is to be able to place
messages and subfolders in a folder at the same time.
This is with mbox format files (I can't use maildir).
The old version of dovecot doesn't seem to support that,
you can have either subfolders or messages in a folder,
but not both.

Does the current version 1.1.3 support it?

Best regards

PS:  Please CC me because I'm not subscribed to the

You can't do that with mbox in any version of dovecot, and I don't think you 
can do that in any other IMAP or POP3 server that I know of.
 IMHO if you want messages and sub-folders in the same folder you will need 
maildir or maybe dbox when it is 100% stable.

So should I comment out the "mail_location = /var/mail/%u" line?  

Read the wiki I posted. You need to prepend it with what type of mail storage 
format you are using like mail_location = mbox:/var/mail/%u or

mail_location = Maildir:/var/mail/%u depending on your mail storage type.
You also might need to add lines for index.

Re: [Dovecot] Converting from MBOX to Maildir broke procmail and Spamassasin and halted incoming mail

[Scott Silva]

on 9-17-2008 11:39 AM Dan Roberts spake the following:

I could use some help here -

As I use Dovecot I started here when trying to figure out why I could 
not add new mail folders under my Mac's Mail program, but could under 
Thunderbird.


It was quickly pointed out that my system was set up to use MBOX and not 
MAILDIR, and some helpful links and notes were sent back and forth 
giving me a good clue as to how to perform the conversion process.


I did have success in getting my mail accounts converted from mbox to 
maildir, but then ran aground.


I could see all of my existing mail and create new folders, but I could 
not see any of my incoming mail.


What I was late in realizing was that I needed to also adjust the 
settings for my LDA, which as I am using sendmail is procmail, and it 
was suggested that I needed to adjust /etc/procmail to include the line


DEFAULT=$HOME/Maildir/

I did that, but new mail still didn't show up correctly.   I can only 
assume that I have something still not properly adjusted in my procmail 
settings.


Given that I got everything else to work, and even successfully upgraded 
dovecot, it was very frustrating to set everything back to square one 
with mbox so that I had a functioning system once again.   I am about to 
have some time on my hands and am going to try again - but this time I 
thought I would ask for help before I possibly loose my ability to 
receive new mail - makes reading those suggestions very hard.


At present, my etc/procmailrc file is like this.
---
[EMAIL PROTECTED] etc]$ cat procmailrc
# send mail through SpamAssassin
:0 fw
* < 256000
| /usr/bin/spamc -f

In each users Home directory I have a .procmailrc file that further 
directs things on a user level.

For my directory this file is currently
---
[EMAIL PROTECTED] ~]$ cat .procmailrc

PROBABLYJUNK = /home/dan/mail/probably-spam

:O H
* ^X-Spam-Status:.*Yes

I admit that I set up Spamassasin some years ago and though I have 
updated things now and then, I don't recall all of the reasoning behind 
the setup - just know that it has been working.


Whether I put the new line "DEFAULT=$HOME/Maildir/" in one file, the 
other or both - I got no incoming mail.  My guess was that I had 
offended promail in one way or another.


So, as I prepare to do the MBOX to MAILDIR conversion once again, does 
anyone have any guidance to offer for how to properly adjust the 
procmail files so that I can continue to filter spam?


Much appreciated.

How old is the distro on the system?
Older versions of procmail don't support maildir.

How about a "ls -la /var/mail/wfoatst"

What do you use for your LDA?

Hi Scott -

How would I tell?   I built the box from scratch and set up CentOS Linux 
5 up on it - over one year, probably not more than three.


I had been running with a RedHat system prior to that - and I may well 
have copied the procmailrc settings from that -- don't actually 
recall.   But Dovecot, Procmail and Spamassasin all came up fresh with 
the install of CentOS.



Everything should be new enough to work.
I can't help you with the procmail recipe as I do all my spam and virus 
scanning with MailScanner. All done before the LDA.


Your setting of DEFAULT=$HOME/Maildir/ should have worked unless either the 
Maildir directory in the users home was not there or not accessible due to 
permissions.


The link to the procmail page might nudge you in the right direction.

Are you trying to have *all* mail in /var/mail/%u or just inboxes?

I'm not sure how well that is going to work. You might need some sort of home 
directory, but your earlier conf had mail location and home directory pointing 
to the same place. That location can't be a directory AND a file.


Do users have home directories on this server or is it all virtual?

Maybe this has more clues;

We have home directories on the server.  Virtual user's can login (at least 
I've been able to verify that from using telnet to port 143).  Yes the earlier 
mail was different.  I can go back to that configuration if I need to.  
Meanwhile I'll take a look at the link you sent.  Thank you!


Then try this;
mail_location = mbox:~/mail:INBOX=/var/mail/%u

Make sure the home directories map properly and not to /var/mail/%u from 
however you auth. The above puts IMAP folders in a folder called mail in the 
users home directory, and the inbox in /var/mail/%u.


Dovecot will also store its indexes in the ~/mail directory, so it has to be a 
folder.

No compiler, no compilation. Easy?

what's a complier?


It compiles source code into a binary executable.


so where does a newbie get this complier?

Please be careful here. If you are that new that you don't know what a 
compiler is or where it is found, you need to do some reading so you don't 
leave your equipment vulnerable to be attacked by the scum of the earth. Once 
they hack your server, it is their server, and will flood the rest of humanity 
with spam and viruses...and you will get the blame by your ip addresses being 
added to every blacklist that exists.


Linux is a fun and interesting way to learn, but it is also a very full

A pop3 user probably wouldn't be using any server side filtering. If you have
mostly pop3 users you should be just adding headers or modifying the subject
so they can client side filter them.

I don't think there should be any default server side filtering except for
either tagging or deleting said flotsam. A user should be technically able to
know how and what the filters are and how to use them, and be using IMAP if he
wants server side filtering that moves mail around.

Besides what you propose probably violates a few RFC's.

With Dovecot set up properly, you should be leaving any client settings for
directory blank. In thunderbird you shouldn't have to set "IMAP server
