We just moved from HPUX to linux and there we had the problem, that with IMAP
and UW-IMAPd you had to specify a Folder Path in the client. With Dovecot and
Maildir you don't need this.

Check if your users have set this folder path. That solved a lot of problems
here.

[Dovecot] userdb override?

[Leroy van Logchem]

Hi,

I used to change the mailbox root for some users using a custom userdb 
file which contains lines like:

doe::2:200::/u/doe::userdb_mail=mbox:/u/doe/Mail:INBOX=/var/mail/%u

The logfiles shows the mail location stays default ( rc15 worked ):

Re: [Dovecot] userdb override? [SOLVED]

[Leroy van Logchem]

 userdb:
   driver: passwd
   args: /etc/userdb_extra
 userdb:
   driver: passwd-file
   args: /etc/userdb_extra

Got it working again. The userdb driver: passwd shouldnt point to the 
userdb_extra file and the passwd-file should be configured first. The 
sequence does matter, after the first hit it doesnt look futher.

Dunno if it matters, but you've used passwd with the file first, try 
using passwd-file before the passwd driver.

BTW: passdb and userdb are not consistent.

[Dovecot] Dovecot should raise the limit of file descriptors at startup...

[Peter Eriksson]

We've run into a situation where the Dovecot master process "dovecot"
runs out of file descriptors on Solaris 10 since the default is
only 256:

# plimit 1
1:  /sbin/init
   resource  current maximum
  time(seconds) unlimited   unlimited
  file(blocks)  unlimited   unlimited
  data(kbytes)  unlimited   unlimited
  stack(kbytes) 8192unlimited
  coredump(blocks)  unlimited   unlimited
  nofiles(descriptors)  256 65536
  vmemory(kbytes)   unlimited   unlimited



Output from "pfiles" after we raised the limit manually:

# pfiles 26378 | head -10
26378:  /ifm/sbin/dovecot -c /etc/dovecot.conf
  Current rlimit: 16384 file descriptors

Perhaps the Dovecot master process should raise it's own limit to the
allowed maximum when it starts? (getrlimit()+setrlimit()), or be
user configurable?

Has this been discussed somewhere before?

[Dovecot] Imap service and quota

[Miguel]

Hi, i have just migrated from courier-imap to dovecot. im using it with 
vpopmail, the pop service is working ok but the imap service for imp 
webmail is not writing the quota information to the maildirsize file, as 
recommended in the docs, i have this in dovecot.conf :


plugin {
  # Quota plugin. Multiple backends are supported:
 #   dirsize: Find and sum all the files found from mail directory.
 #Extremely SLOW with Maildir. It'll eat your CPU and disk I/O.
 #   dict: Keep quota stored in dictionary (eg. SQL)
 #   maildir: Maildir++ quota
 #   fs: Read-only support for filesystem quota
 quota = maildir

 }

This only happend with imp/imap, there is not problem using a pop client

[Dovecot] Subscriptions - delivering to different folders

[bichumo]

Hi,

I am using Postfix and Dovecot. I have set up [EMAIL PROTECTED], 
which gets mail copies from [EMAIL PROTECTED] [EMAIL PROTECTED] 
[EMAIL PROTECTED], the copy option is set in postfix recipient_bcc_maps = 
path_to_file_recipient_bcc. In recipient_bcc file I have:


[EMAIL PROTECTED] [EMAIL PROTECTED]
[EMAIL PROTECTED] [EMAIL PROTECTED]
[EMAIL PROTECTED] [EMAIL PROTECTED]

Postfix does the job and copies user1, user2, user3 emails to 
backup_mailbox. But I also want to filter mails in backup_mailbox and to 
put user1 mails to USER1 folder in backup_mailbox, user2 mails to USER2 
folder in backup_mailbox and so on. How this is possible? I made an 
entry in subscriptions file of user1, user2, user3. Now I have folders 
.user1, .user2, user3 in backup_mailbox folder and I can also see these 
folders through webmail client (squirrelmail), but how do I put email 
copy which comes from [EMAIL PROTECTED] to [EMAIL PROTECTED] to 
go not to main folder of backup_mailbox but to USER1 folder in 
backup_mailbox folder.


Thanks for any suggestions.

Re: [Dovecot] Subscriptions - delivering to different folders

[Luis Pablo Michelena Scaffo]

May be wrong (am I?), but i think that perhaps you'are looking at the 
wrong hammer. If I had to  do that i'd use  the lda (e.g procmail, 
modifing .procmailrc in the backup user homedir) to achieve that.

My half cent,
Luis

[Dovecot] Exim-dovecot-Horde/imp-Mysql

[Andre Eisvogel]

Dear all,

I'm running a linuxbox with ' Dovecot<->Exim<->horde/IMP<-> Mysql ', this is a 
very good combination and works excellent for the system users.

Now I want to change the configuration and authenticate against the mysql 
database from horde. That way it is much easy for me to create (virtual) mail 
users. I also want to use the mail alias of the horde users for Exim and 
Dovecot.

My questions are; is it possible to use the horde mysql database for this? And 
is it also possible for the mail alias of horde?
If this is possible, is there a howto of this configuration?

The packages i'm using are:
Exim 4.67
Dovecot 1:1.0.3
Horde 3.1.4
Mysql 5.0.45
PHP 5.2.3

Does it matter that the UW-IMAP folders are in mbox-like format?  It

Yeah, it does matter. Dovecot doesn't allow you to mix-and-match 
different mail storage formats very easily. You may be able to set 
something like that up with the Namespaces support in Dovecot, but the 
easiest thing to do is to convert your mbox files into Maildir.

Thanks Kyle, but how do I convert the mbox-like IMAP folders into 
something Dovecot can read with the new config?

Hi Philipp,

Our users are using Outlook Express and Outlook.  I just set up an IMAP 
account that is having the issue and I didn't specify any folders.  I 
just used the defaults.


What's even more odd is that when I created a new folder within Outlook 
Express, I see it in /home/USERNAME/Maildir/subscriptions, but I don't 
see the folder anywhere...how does Dovecot see these IMAP folders?  Is 
there some sort of tag that is contained within each Maildir email that 
tells what folder it goes in to?

Have you added the quota plugin to the imap service?
As far as I've understood the docs it needs to be in every service.
However, I'm new to dovecot, too, so I may be wrong.

[Dovecot] maildir question

[Tim Bates]

If I copy message files (from a command prompt) will dovecot get upset 
or confused? Do I need to delete index files or anything like that?
I ask because I need to restore some messages from a backup, but not 
restore the entire maildir. I tried some the other day as a test, but 
the user is saying that they didn't appear.

Dovecot is supposed to cope just fine. See

  

>  Do I need to delete index files or anything like that?

I don't know about maildir (I'm using mbox), but I'd expect Dovecot to
reindex whenever it "sees" the directory more recent than the index
file.

Have you checked the creation dates of the maildir and of the
corresponding index?

It's part of how Maildir is designed.

Since Dovecot can quite happily deal with other agents (user or delivery) 
meddling with the files and moving them about, it will also happily deal with 
new messages arriving magically.

Cool. That's good to know.
I got word back that it showed in our webmail so it appears to be the 
client they are using (Outlook of course).
