[Dovecot] How to set MDNSent flag on a large amount of mails?
by Patrick Nagel 03 Jun '08

03 Jun '08

Hi, after having moved a big mail archive to IMAP, I've now got the following problem: The MUA asks to send an MDN on all those old messages that contain the 'Disposition-Notification-To' header when opened. I'd like to set the $MDNSent flag on those (>10000 in a deeply nested directory structure) mails. After having read http://wiki.dovecot.org/MailboxFormat/Maildir I wrote a script that changed the filename of mails in all directories that contained the header, so that the filename contained a 'b' in the last part of the filename (after the comma), because I found '1 $MDNSent' in Maildir/dovecot-keywords. I then discovered that there can be a 'dovecot-keywords' file in each directory, and all of those files can have different flags in different order. Do I really need to write a script that evaluates each dovecot-keywords file, figures out which letter corresponds to the flag and rename the files (per directory) accordingly? Isn't there a more simple way?

[Dovecot] spamassassin, postfix with dovecot lda?
by George Mamalakis 03 Jun '08

03 Jun '08

Hi all, I am trying to setup a mail server using postfix (virtual_mailboxes), spamassassin and dovecot, along with SQL where appropriate. From my research so far I realized that, for several reasons, it is required for me to use dovecot LDA instead of maildrop, local, procmail or other alternatives. My configuration was working flawlessly, until spamassassin per-user configuration came to play. If I just wanted an MTA anti-spam gateway, I could directly call spamassassin via master.cf, or through some helper "content-filter-application" (like amavis or amavisd-new), and everything would work just fine (I tried and tested many such configurations with success). But when antispam per user preferences became my concern (Bayesian filters and classifier), I realized that spamd should be called by the LDA. With procmail this was a trivial issue, with dovecot-lda I was unable to find any solution on the web or other documentation. So my question is as follows: Is there a way to call spamc from dovecot-LDA (and/or dovecot-sieve), or is there an alternate way to do this for a site with virtual mailboxes configured with dovecot-lda? Thank you all in advance, regards, -- George Mamalakis IT Officer, Department of Electrical and Computer Engineering, Aristotle Univ. of Thessaloniki, Greece

[Dovecot] v1.1.rc6 released
by Timo Sirainen 03 Jun '08

03 Jun '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc6.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc6.tar.gz.sig This is it. The first v1.1 release that actually deserves the "release candidate" name. It contains everything I require from v1.1.0 release. There are two bugs left that I'd like to get fixed, but they won't block v1.1.0 release: * index_mailbox_set_recent_uid() assert (reported by Diego Liziero) * Maildir not always finding new messages and returning them as empty (reported by Anders). The major change in v1.1.rc6 release is the SORT indexing half-rewrite. I hadn't much stress tested that code before, and once I started I just kept finding more and more weird bugs and it became extremely difficult to figure out how to fix them, so I finally decided to just redesign how it's supposed to work and then implemented that. The resulting sort code is a lot cleaner and it should also perform better (although it could still be improved a bit: the basic binary searching could be replaced with one that first binary searches between already-looked-up sort-strings and only after that binary searches the resulting space which requires slower sort-string lookups). Hopefully there are also no stupid bugs left like returning messages in wrong sort order. :) I've been wasting time this past week getting new stuff for my new apartment, but that's nearly done now. I think (hope) I'm going to be more productive in here, there are less neighbours behind walls/floors (just 1), so less potential for annoying noises. :) Thinking also seems to work better when there's more space to walk around. And finally, the changes since v1.1.rc5: * Index file format changed a bit. If an older Dovecot v1.1 reads index files updated by rc6+, they may give "Invalid header record size" or "ext reset: invalid record size" warnings. v1.0 won't give these errors. * IMAP: LIST .. RETURN (X-STATUS) command return now LIST entries before STATUS entries. * zlib plugin: Uncompress if the message begins with zlib header instead of looking at the 'Z' flag. This fixes copying with hard links. Based on a patch by Richard Platel. + IMAP: SORT index handling code was half-rewritten to fix several bugs when multiple sessions were sorting at the same time. The new code is hopefully also faster. + Maildir: If POP3 UIDL extra field is found from dovecot-uidlist, it's used instead of the default UIDL format (or X-UIDL: header). This allows easily preserving UIDLs when migrating from other POP3 servers. Patch by Nicholas Von Hollen @ Mailtrust. + Maildir: ,W=<vsize> is now always added to maildir filenames + deliver: Avoid reading dovecot-uidlist's contents if possible. + Added %T modifier = Trim whitespace from end of string - IMAP: Fixed some bugs in LIST-EXTENDED implementation. - IMAP: If client tries to change the selected mailbox state while another command is still running, wait until the command is finished. This fixes some crashes and other unwanted behavior. - allow_nets userdb setting was broken with big endian CPUs

[Dovecot] overview of patches used in Fedora
by Dan Horák 03 Jun '08

03 Jun '08

Hi, I have gone through the patches that are used in the Fedora package and probably only the "mkcert-permissions" [1] can be considered to be included upstream. It is dated into package version 1.0-0.beta2.3, but I cannot find any particular reason for the inclusion (like a bug in bugzilla, etc.). Some (winbind support, quota warnings) were obsoleted by dovecot 1.1, two are used for distro specific settings. So the only real patch that remains is the "pam_setcred" [2] patch that fixes https://bugzilla.redhat.com/show_bug.cgi?id=146198 Current state of the package for Fedora is at http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/ Dan [1] http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/dovecot-1.0.beta2-m… [2] http://cvs.fedoraproject.org/viewcvs/rpms/dovecot/devel/dovecot-1.0.rc2-pam… -- Fedora and Red Hat package maintainer

[Dovecot] Unsuccessful POP sessions on dovecot-1.0.3-13_60
by Patrick Ben Koetter 03 Jun '08

03 Jun '08

A Client runs a RAS network. Users access mailboxes using Outlook Express. The server runs dovecot-1.0.3-13_60. Almost a week ago users began to report that they can't retrieve their mail. The session starts, they seem to retrieve messages, but then the client reports a problem and the session is terminated. Here's what I have in the log: May 28 08:56:46 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 08:59:00 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 08:59:29 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:03:49 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:04:24 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:12:11 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:14:32 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:17:10 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:17:52 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:20:27 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 May 28 09:23:23 server dovecot: pop3-login: Login: user=<user@client>, method=PLAIN, rip=::ffff:10.11.9.18, lip=::ffff:10.11.9.108 May 28 09:30:05 server dovecot: POP3(user@client): Disconnected top=0/0, retr=5/448621, del=0/58, size=8991962 What I see is that the client seems to try to retrieve the same mails (retr=5/448621) over and over again. If they login using IMAP they don't experience any problems. Any idea what this could be? Rumor has it it's a know problem with Outlook Express and its POP implementation.

[Dovecot] Purging Deleted Messages
by Carlos Williams 02 Jun '08

02 Jun '08

I noticed today I checked a users mailbox with the mutt command: mutt -f /home/bob/email/ There I saw he had 100 messages that had been deleted but not yet purged from his inbox so they're still using up disk storage on my email server. My question is does Dovecot have a process to automatically delete these messages after a certain period of time? I would like to think that they don't just sit in a users mailbox for years waiting to be purged, right? Does anyone know exactly how this works? I checked my own mailbox using mutt and I see 11 messages that are deleted from my Thunderbird client but are still on the server (marked for deletion). How long do these messages stay there? -- Man your battle stations...

[Dovecot] deliver & override homedir
by arne van theemsche 02 Jun '08

02 Jun '08

Hi We're in the phase of converting our existing unix-based users to virtual users. Goal is to make mail-spool totaly independent of home-spool. For that reason, NO files can be written to home. I've solved the problem for all files, except for .dovecot.lda-dupes. I can see in duplicate.c #define DUPLICATE_PATH "~/.dovecot.lda-dupes" I thought being clever and override in the userdb passwd following args = home=/var/spool/mail/%1n/%2n/%n but deliver totaly ignores that. does anybody has tips? kind regards Arne

[Dovecot] deliver saving mails with hard linking
by Timo Sirainen 02 Jun '08

02 Jun '08

http://dovecot.org/tmp/deliver-multiple.diff for Dovecot v1.1 implements -p <path> parameter for deliver, which reads the input mail from the specified path instead of stdin. With maildir and hardlink copying enabled, it also tries to hard link the file to destination instead of copying it. So to get the same mail delivered to multiple recipients using hard links, you'd have to write a small wrapper script that stored the mail temporarily somewhere and then called deliver for each recipient using the -p parameter. Any thoughts on if this should go to v1.1 like this? Some problems: - If you're not using a single UID/GID you probably have to make the file world-readable. - A wrapper script is kind of ugly, so it would be nice if deliver took a list of all recipients as input. But the deliver code is currently ugly enough that this would require larger changes. - Am I forgetting something?..

Right. This isn't implemented yet. Also I don't think it should rely on Message-ID: header proving the uniqueness. There are two ways this can be implemented reliably: 1) If the message is sent to multiple recipients using same RCPT TO command, all the recipients could be given to deliver as parameters, and deliver would know that it's the same message and they could be hard linked. 2) Keep some kind of a hash database where hash is e.g. SHA1 sum of the entire message. All messages could be then stored in some global directory and hard linked from there to users' mailboxes. When receiving a new message using an existing hash, it could still compare byte-by-byte the files to make sure that it's not a hash collision before hard linking the file. 1) probably wouldn't be too difficult to implement and probably would solve your problem (assuming the problem is that people are mailing 100MB attachments to everyone inside a company). But I don't think I have time to do it myself..

[Dovecot] Dovecot hard link problem
by 도원철 01 Jun '08

01 Jun '08

My company recently changed mail server from cyrus to dovecot. The problem is that dovecot does not support hard links for message files with same message ID. I turned on the ‘maildir_copy_with_hardlinks’ option in dovecot.conf, but it does not seems to have relation to this problem, am I misunderstood? Hard links are created when move or copy messages from one folder to other folder, but when deliver creates messages this option does not works. Our mail storage will be exhausted in few days. If you have some idea to solve this problem, please please help me. Or If you fix this problem, I will happily pay for it at reasonable cost. I installed dovecot 1.0.13 and postfix 2.5.1.

Whenever I try to search on my dovecot test install, dovecot dies. It immediately spawns a new process, which the client tries to connect to, and send search commands to, causing that to die, and so forth.

[Dovecot] fetchmail on demand
by Graeme Vetterlein 31 May '08

31 May '08

I hoping this is an RTFM ... and somebody can point me at the correct 'FM' :-) I've just spent a while setting my new Debian , allways-on box in what I suspect is a generally useful configuration. I have fetchmail(1) collect mail from many mailboxes via pop3. I store these mails in different mboxs according to rules in procmail(1) I then offer these out to the household via imap in dovecot(1) . I have fetchmail(1) set to poll the ISPs every 5 minutes, this seems to work fine, but there are two issues: 1: The constant polling keeps the disk spinning for no good reason (most of the time) 2: If I check my mail via a mail reader using imap to the local mboxes ...there could be mail sitting on the ISP servers I don't see (for 5 mins) Now what would be much nicer, would simply be to have dovecot(1) issue the fetchmail(1) command whenever it it got an imap request. I general what I guess I would like is: "When a request comes in (via imap) fork off a command who's name is given in the conf file. ... imap_pre_cmd="xxx" -- Graeme

[Dovecot] Sieve Editheader Extension?
by Michael K Sanders 31 May '08

31 May '08

I've done extensive searches, and there is virtually no information about actual implementations of the draft Sieve Editheader Extension (which provides 'addheader' and 'deleteheader' actions): http://www.ietf.org/internet-drafts/draft-ietf-sieve-editheader-11.txt Is anyone currently working on this for Dovecot Sieve? If not, are there any plans to do so? And before I start digging through the source, is the architecture amenable to this functionality? Thanks, :: Mike ::

[Dovecot] Web-based shared calendar synchronizable with Outlook
by Samuel HAMEAU 30 May '08

30 May '08

Hi, I know this request is a a little off-topic but may be interesting for dovecot users (at least i hope!) Does anybody has already had an experience with a calendar sharing solution including a webcalendar and an outlook connector, "compatible" with dovecot ? Today, there are many projects aiming to be a "M$ Exchange Killer" (such as Zimbra, OBM, open-exchange, etc) but they offers a global package with MTA and imap server included. I saw the page about BynariConnector (http://wiki.dovecot.org/HowTo/BynariConnector) but unfortunatly they do not provide a webmail :( I'm afraid What I am looking for is a shared agenda solution providing a webcalendar, an outlook connector and eventually a pda connector, using (or not) dovecot, and a corporate ldap server... What are you guys using ? sam

It appears to be that 1.1 is a lot faster that 1.0. And server load levels have dropped.
