Hi! I would like to find a way to not delete messages when they are downloaded via pop3, is that possible with dovecot? Gmail do this, I dont know how they mark messages that have been downloaded to avoid clients to download it again, but it looks like a good resource! Thanks for the help!

Your Getmail app may not be truly running as root and thus does not really have permission to do what you want. you may need to do the same for the group as well Unix permissions are weird sometimes, like a $100 television tube that protects a 50 cent fuse by blowing first. It does look like (from your use of /usr/local/*****) you built dovecot to run out of /usr/local. One last thing, as a security idea, try something like master { path = /usr/local/var/run/dovecot/auth-master mode = 0600 user = dovecot_user group = dovecot_group } and set your postfix line that calls deliver to match: dovecot unix - n n - - pipe flags=DRhu user=dovecot_user:dovecot_group argv=/usr/local/libexec/dovecot/ deliver -f ${sender} -d ${recipient} (try to have dovecot run as an unprivileged user as much as you can)

[Dovecot] Maildir handling
by Sascha Holzleiter 14 Jan '08

14 Jan '08

Hi, we just setup a new mailserver for our company with some sieve filtering in place. Everything works as expected but there is one flaw. We setup the per user sieve filters in files within the users mailbox maildir as follows: lrwxrwxrwx 1 mail mail 21 Jan 13 17:20 .dovecot.sieve -> sieve/phpscript.sieve This link is actually picked up by dovecot and being announced as an IMAP folder which gives an error in certain MUAs as they try to access it. Is there a way to let dovecot check if the link is really a maildir, so lets say a directory with a maildirfolder file within it? Or just to hide this link from dovecot so its not advertised as an IMAP folder? Greetings, Sascha

[Dovecot] Unexplained MDA bounce backs
by Dean Manners 14 Jan '08

14 Jan '08

I have recently noticed that some of our internal mailer scripts are causing Dovecot-LDA to generate Mailer Delivery Subsystem messages. The following Dovecot-LDA message is generated: ---- Message body ---- Your message was automatically rejected by Dovecot Mail Delivery Agent. The following reason was given: Unknown error ---- Message body ---- ---- Message header ---- Return-Path: <MAILER-DAEMON> Delivered-To: bounces@xxxxx Received: by mymachine.xxxxx (Postfix, from userid 5000) id 5772568300; Mon, 14 Jan 2008 18:00:56 +1100 (EST) Message-ID: <dovecot-1200294055-774265-0@mymachine> Date: Mon, 14 Jan 2008 18:00:55 +1100 From: Mail Delivery Subsystem <noreply@xxxxx> To: <bounces@xxxxx> MIME-Version: 1.0 Content-Type: multipart/report; report-type=disposition-notification; boundary="21506/mailfilter02" Subject: Automatically rejected mail Auto-Submitted: auto-replied (rejected) Precedence: bulk ---- Message header ---- Initially I thought these were being caused by Delivery-Receipt requests, however have since tested this and is not the case. I have tried to snoop through the logs (unfortunately on a very busy mail hub) using the Message-ID, however this doesn't seem to lead me back to the original message - only the MDA notification. I can only ascertain that its isolated to our scripts, as the bounces@ address is specifically used by them. Any ideas what would cause/trigger the "Unknown error" automatic rejects ? System config is -Postfix 2.3.4 with MySQL backend -Dovecot 1.0.rc26 with MySQL backend, using only deliver. All mail deliveries are otherwise fine.

Re: [Dovecot] Imap proxy with tls?
by Someone Something 14 Jan '08

offlineimap looks like it will work. Do you know if it works well on big changes? I have about 1.5 gigs of email at the local site that will need to be uploaded to the main server. After its uploaded it will have to weed through it all during the sync every time. Think that will be ok?

[Dovecot] Imap proxy with tls?
by Someone Something 14 Jan '08

14 Jan '08

Hello all, I have a server with dovecot installed with imap and tls working (call that the remote server). Now I want to have a few computers at the same place to access the same account on the remote server. I have another server (call this the local server) at the local site to do this with but am not sure how to do it. The proxy setup http://wiki.dovecot.org/PasswordDatabase/ExtraFields/Proxy looks about right but that does not seem to support tls? I need tls going from the local server to the remote server. I want all emails on the remote server to be the same as on the local server. This way all clients at the local site have very fast access to email and can still get to the email when not at the local site. Any suggestions? Thanks

[Dovecot] Indexes
by Daniel L. Miller 13 Jan '08

When something "bad" happens to the indexes, my e-mail client (Thunderbird) reports an "unable to succeed" error on opening a mailbox. Leaving that mailbox and coming back works fine. Is this expected behaviour? -- Daniel

[Dovecot] Custom 'quota exceeded' message + Sieve script from database
by Przemyslaw Wegrzyn 13 Jan '08

13 Jan '08

Hi! I'm quite new to Dovecot. helping my friend to migrate from Courier-IMAP to something more efficient, we are evaluating Dovecot at the moment. I had to prepare 2 small patches for Dovecot to suit our needs, and I've decided to post it here. I'm not fully familiar with Dovecot architecture yet, I'd appreciate if someone could look if these changes make sense (i.e. doesn't break anything). And of course, maybe someone is interested as well. 1. Customized "quota exceeded" message. http://czajnick.sitenet.pl/dovecot/dovecot_1.0.9_quota_exceeded_message.diff - quick hack to let me define custom message instead of typical "Quota exceeded", simply by using plugins { quota_exceeded_message = ... }. Browsing this mailing list I've seen some posts about such feature being implemented in Dovecot. Is it done in a similar way? Which stable version is the first to include this functionality? 2. Sieve filter modification http://czajnick.sitenet.pl/dovecot/dovecot_sieve_1.0.2_envscript_patch.diff In our systems we currently use a modified maildrop MDA that picks the filter script from the database instead of the file. This has proven useful - end-user's administration panel doesn't need any special permissions (or networking capabilities), as it doesn't need to access the filesystem - it is reduced to a plain database web-app. The patch above makes the delivery agent check for the sieve script present in SIEVE_SCRIPT environment variable. If this is the case, env var content is used instead of the script stored in a usual file pointed to by SIEVE variable. This makes it trivial to pass the script from the database using base dovecot functionality. A minor drawback of such solution is that the script is re-compiled on each delivery, but I don't think it takes much time to compile a few lines of a script using (f)lex/bison-or-yacc parser. Yes, I've noticed the sieve-manage patch, but I don't want the complexity of managing sieve script over the socket connection (if my understanding of the script is wrong, please correct me). BR, Przemyslaw
