Most people like the more advanced packages like SOGo, Group Office and Horde.

Yes. Return mail_plugins setting from your user_query. For example: user_query = select .., mail_plugins from users where .. BTW. Don't post to list by replying to an existing mail. It preserves In-Reply-To: header and messes up threading.

If Horde runs on the same host, just disable SSL :-) . . .because SSL is for remote hosts (clients) on the network anyway right ? Well, there might be scenarios, when a local user other than root may sniff the connection on localhost, but I think you have no such one. So to encrypt a connection from localhost to localhost is a waste of ressources. In case of Dovecot you'll need one extra file descriptior (and depending on your settings one extra process as well), plus the CPU time to actually do the encryption. Yeah. The certificate is there. Under "/etc/ssl/certs". I was thinking that maybe because the system (and the certificate issuer, horde and dovecot are on the same box. You ask me somewhere about that) is all-in-one, I need to import the certificate somewhere ? see above for the reason. The dovecot wiki says that importing the certificate is only applicable to the client-side (evolution, thunderbird and so on). The webmail-frontend _is_ your client in the view of Dovecot. But since the cert is in /etc/ssl/certs, it should work, but if you validate the cert, the webmail may bark, because you access the SSL-cert with the CN "webmail.domain.gr" by another name "localhost". This is a sign of a man-in-the-middle attack, actually. BTW: Do your SSL IMAP/POP clients also use the name "webmail.domain.gr"? Otherwise they will get a warning as well, maybe each time they connect.

I'll look into option b then. It might not be possible with the .forward approach, but almost certainly is with procmail.

[Dovecot] IMAP client dependence on dovecot mail storage fromat?
Hi, After setting up a maildir tree with :LAYOUT=fs and accessing it with KMail and Thunderbird, various mail client-specific problems appeared, but, as I didn't try with maildir++, I would like to confirm here: does that matter for an IMAP client much if I store mail on server as ":LAYOUT=fs" or maildir++? Can it see differences? I would like to think, that IMAP protocol should provide for all transactions in a standard way and its dovecot's/server's sole business how it stores mail locally. However... These results seem not very good: KMail: try creating a folder "sub" in "parrent" and you'll get "parrent.sub" along with "parrent" on server side. There, however, are no problems with Latvian unicode chars. Thunderbird: it can create a new folder in "parrent" as desired, but it can't display Latvian unicode chars (being such at server side) on client, while, if I try creating a new folder with Thunderbird with these chars, on server it will look somewhat like base64! So I'm really confused. All together these things are pretty frustrating, sure, but I'd like to understand whats the real problem here! signature.asc Description: This is a digitally signed message part.

Yes. Return mail_plugins setting from your user_query. For example:

Thanks. One clarification. If I have:
protocol imap {
mail_plugins = quota imap_quota mail_log

it "adds" to the plugins specified in the conf? Or I have to add every

Re: [Dovecot] sieve 0.1.14: vacation encodes Subject twice
Roland Rosenfeld wrote:
Hi!
I noticed the following problem in dovecot-1.2-sieve-0.1.14:
The following vacation causes trouble with the Subject line:
if not exists ["List-Id", "List-Post"] {
vacation :days 7 :addresses ["t...@netcologne.de"] :subject "=?utf-8?b?w4TDlsOc?= sadasd" "Bin gerade nicht hier.";
}
As you can see, the Subject is already MIME encoded according to
RFC2047.
Starting with sieve 0.1.14 the subject is now encoded by sieve again,
so I get the following in my vacation mail:
Subject: =?utf-8?q?=3D=3Futf-8=3Fb=3Fw4TDlsOc=3F=3D?= sadasd
As you can see, the RFC2047 encoding is RFC2047 encoded, which results
in an unreadable subject.
According to RFC5230 section 4.3 this shouldn't happen:
The ":subject" parameter specifies a subject line to attach to any
vacation response that is generated. UTF-8 characters can be used in
the string argument; implementations MUST convert the string to
[RFC2047] encoded words if and only if non-ASCII characters are
present. Implementations MUST generate an appropriate default
subject line as specified below if no :subject parameter is
specified.
If I understand this right, sieve should do the RFC2047 encoding only
if the string is non-ASCII. But the RFC2047 encoded string is already
ASCII, so it should not be encoded a second time.
Fixed:

[Dovecot] shared namespace problem
Hi List, I've got a problem, setting up shared namespaces. I am trying to setup a Mailbox (Maildir) which is accessible for some users. (For example mailbox "sales" and only sales representive have access to it) Mailboxes can be found under /var/vmail/, whereas looks like foo.bar or peter.griffin ;) Now, if I connect via telnet, loggin in as foo.bar and run a03 SETACL foobar peter.griffin lwrxk everything seems fine. Under /var/vmail/foo.bar is a acl-file dovecot-acl-list Under /var/vmail/foo.bar/.foobar is a acl-file dovecot-acl The contents looks ok. Also there is a generated file /var/vmail/shared-mailboxes.db. But if i now loggin in as peter.griffin and setup command a03 LIST "" "*" or a03 LIST "" "#shared" I can not find any shared mailbox. Above you can find my actual configuration. I've tried several versions of location: under shared namespace, but without success. Hope someone has a clue and point me into the right direction.

Returning mail_plugins from userdb overrides the setting, so it needs to return
all of them. But of course you can do something like:
select concat('quota imap_quota mail_log ', extra_plugins) as mail_plugins
or whatever.
[Dovecot] dovecot-1.2-sieve-0.1.3 compile error
Hi, when I try to compile dovecot-1.2-sieve-0.1.3 on my NAS I get the error below and I have no idea why and who to fix this. I have a Qnap TS239pro NAS with a Intel Atom CPU running Linux. I installed and configured the ipkg dovecot packet (1.2.beta1). Getting mails via fetchmail and send them with deliver to the IMAP. Not I want to include sieve to filter mails as this is not part of the packet I need to compile this by my own.

Re: [Dovecot] Dovecot (IMAP) Hangs sometimes
Exactly! I agree with you! I used to have webmail connect locally via
unencrypted IMAP on port 143, but the problem occurred even more frequently.
So I thought that it could be dovecot not being able to work out both
protocols... I had it like this:
protocol imap {
listen = 127.0.0.1:143
ssl_listen = *:[another port]
}
Then I commented the listen line, and things got better, but not good enough
yet. Strange, uh?
I know I should not be using webmail locally via SSL. But I got less errors
like that. Altough, I know once I get the problem solved, I can go back to
the correct solution.
Just for the record: My mail server is running super fast! The problem
happens only at specific moments, twice a day, only.
Otherwise, what's the other configuration that could be eating up resources?
BTW, I got plenty of CPU (2xQuadCore 3.0) and memory (32GB).

[Dovecot] Next message unexpectedly corrupted in mbox file
Hi, I am seeing this on one of my servers: Jan 8 10:08:58 l1 dovecot: IMuser(user): Next message unexpectedly corrupted in mbox file /home/user/Mailbox at 10558 I have never seen this before, and google yields no results except when this warning was added to the source code here: http://www.dovecot.org/list/dovecot-cvs/2009-December/015177.html The user has deleted all of the mail in the Mailbox but the problem persists. Any ideas? Justin.
Re: [Dovecot] Dovecot (IMAP) Hangs sometimes
The specific moments are at about 9:40 am and 2:30 pm. Exactly when I have most of my users connecting simultaneously (when they arrive in the morning and back from lunch break). At these exact moments, dovecot hangs. Anyways, I took a look at http://wiki.dovecot.org/LoginProcess. I increased the default login_max_processes_count from 128 to 256 and restarted dovecot. Right before doing this (2:24pm, at this time, imap was getting slow already and dovecot was about to hang) I checked my processes every second: ps -ef | grep imap-login | grep dovecot | wc -l and the results varied from 149 to 152. After setting login_max_processes_count to 256, I hope the problem is fixed. I didn't do anything related to open file descriptors.

Ok, since I've received no responses on my original post, I went about digging through the source. I *think* I found the line which I need to change in order to check the available quota, but not include the current message size in the calculation. My C++ is rusty to say the least, and I'm having a bit of trouble understanding some of the functions, so any help will be appreciated. This is part of the "quota_default_test_alloc()" function. Ideally the patch would add the ability to enable/disable this capability in the dovecot config file, but I'm just looking for a quick 'n' dirty hack at the moment. -- dovecot-1.2.9/src/plugins/quota/quota.c @@ -969,4 +969,4 @@ *too_large_r = FALSE; - if (ctx->count_left != 0 && ctx->bytes_left >= ctx->bytes_used + size) + if (ctx->count_left != 0 && ctx->bytes_left > 0) return 1; -- Any help would be appreciated!

[Dovecot] stripping attachments
there is a windows tool that strips attachments from emails on the server. i think it works for exchange. is there a tool or a way to do this for imap? i don't mean a mail filter that would strip them before the user sees them, i mean that the user could actively cooperate to reduce mail storage space, yet keep the original email on the server sans attachment.

yes, this is doable. e.g. mutt client can delete attachments from
messages stored on imap server. in reality it would get the message,
strip attachments, upload the message witout attachments and delete the
original message with attachments.
i believe mozilla thunderbird also offers a similar option.
i don't mean a mail filter that would strip them before the user sees
them, i mean that the user could actively cooperate to reduce mail
storage space, yet keep the original email on the server sans
attachment.
right. yes, this is done by the approach described before.
or you could use the imapsize tool:

[Dovecot] uw-imap compatability hack?
Hi all Apologies if this question has already been asked before... I'm migrating from a uw-imap setup where the mail folders were in a subdir mail/ in the users' home directories. All of the clients are configured with 'IMAP server directory' set to mail/ (Thunderbird) and it would be difficult to change this on the clients (there are 1000s of them) I want to use maildir and I have converted the original mbox files in ~mail/ to maildir format. So in ~Maildir/ I now have: cur dovecot.index dovecot.index.cache dovecot.index.log dovecot-uidlist .Drafts new .Sent-Items .Spam subscriptions tmp .Trash if I remove the mail/ setting from 'IMAP server directory' in the client, then everything works as expected and all the folders are visible. With this setting in however, only the inbox is visible and attempts to click on another folder, say Trash result in the client error: Mailbox doesn't exist .mail.Trash I've tried various namespace configurations I found in the namespaces wiki example but none seem to work. What I would really like to happen is for dovecot to ignore this setting supplied by the client and not to prepend .mail onto the folders it is looking for. Is there a clever namespace that will do this for me, or some other setting or symlink trickery? Ultimately I want to support clients that might have both mail/ and nothing set in this box. Using dovecot 1.07. kind regards Simon -- This e-mail and any attachment is confidential.

Re: [Dovecot] Sieve > Pigeonhole > external storage with LDAP or other data source available to dovecot
Martin F. Foster wrote: I am looking at porting and generalizing an old in-house patch that I'm using for the CMU Sieve plugin. It allows sieve script to test & lookup arguments from LDAP. Before getting too involved in this, I'd like to discuss my goals here in the hopes that someone else also thinks this would be useful. Many heads may make better design? I thought this would be an excellent opportunity to test the new Pigeonhole plugin support and also to do something interesting with the namespace functionality of the variables extension. That is why I gave this a short look, which promptly resulted in a preliminary implementation. If you want to play around with it, you can download it from: http://hg.rename-it.nl/pigeonhole-sieve-extdata/ It will compile and run with both Pigeonhole for Dovecot v1.2 and Pigeonhole for Dovecot v2.0, but only with the tip Mercurial revisions (since only those have plugin support). I swiped together many of the ideas posted here on the mailing list and from those I concocted the following Sieve language extension: http://hg.rename-it.nl/pigeonhole-sieve-extdata/raw-file/tip/doc/rfc/spec-bosch-sieve-external-data.txt Note that - despite its looks - this is not intended as a IETF draft submission, but merely as a internal memo for the specification of this vendor-specific extension (in a familiar format). It could be further extended with an 'extdata_open' command to dynamically link a resource URI to a data store identifier, but thus far I did not bother to write that idea down. All the necessary installation information should be found in the INSTALL and README files. Note that I have only tested this against a flat file dict and not something like SQL. So that may still be broken somehow. Tell me what you think. Regards, -- Stephan Bosch step...@rename-it.nl
[Dovecot] outlook 2007 can't see public folders more than 1 deep
dovecot-1.2.9
I have a public folder using ACLs to determine who can access it.
namespace public {
separator = /
prefix = shared/
location = maildir:/var/maildir/shared
subscriptions = no
}
Outlook 2007 can't see any folders except at the top level. It can
create them just fine, but can't see them after quit and restart.
For example, I can create the folder shared/foo/bar but on restart
outlook only sees foo as a folder without subfolders (no + to expand it)
and doesn't see bar anymore. In fact I can delete the folder foo
in outlook and then BOTH .foo and .foo.bar directories are removed
on the server.
When you click on foo, the error message in the mail pane is "Cannot
display the folder. The folder 'foo' cannot contain items. This is
most likely a limitation of your IMAP server. In order to create a
folder that can contain items, be sure not to append '/' to its name
as you create it."
