[Dovecot] What causes dovecot to rebuild dovecot-uidlist?
by Pat 02 May '10

02 May '10

Hello, In what situations will Dovecot 1.2.11 rebuild its uidlist? I am using the maildir storage format, and I am also modifying the uidlist manually (so it's possible I could jack* things up). I have found some related code in maildir-uidlist.c: maildir_uidlist_next. 1) Blank filename or UID 0 2) Any UID not being greater than the proceeding UID 3) Any UID being greater than ~4 billion. 4) Any UID being greater than the suggested next uid. 6) If a filename contains a / 7) General header line sanity checking. Are there any other sections of the code that do sanity checks on dovecot-uidlist (for Maildir type storage)? And optionally do you agree that maildir_uidlist_set_corrupted is the best place to watch to see if I have mangled the uidlist? Thanks in advance, Pat * I insert into dovecot-uidlist manually when I deliver new messages, or discover a message that is not in uidlist for some reason. For compatability reasons I maintain a completely separate cache. If there is a better way to keep the uidlist up to date when the user isn't necessarily accessing the account via dovecot imap, I'm open to suggestions. However my situation is fairly unique I think.

[Dovecot] My dovecot does not store Thunderbird flags
by Julien Buratto 01 May '10

01 May '10

Hi all, my Dovecot 1.1.20 does not store flags (I mean, Thunderbird Labels like ToDo, Important and so on..) When logging in via telnet, I get: . examine INBOX * FLAGS (\Answered \Flagged \Deleted \Seen \Draft NonJunk $MDNSent Junk $Forwarded NotJunk receipt-handled $Label7 $label1 $label2 $label3 $label4 $label5 expired_2w expired_2m delete rimandata forwarded) * OK [PERMANENTFLAGS ()] Read-only mailbox. As per Thunderbird mozillazine page about tags (http://kb.mozillazine.org/Tags#IMAP) that's what the issue is. PERMANENTFLAGS should allow /* while in my server it's empty. Could someone point me how can I change this behaviour or some hints ?

[Dovecot] UK Blackberry BIS and Dovecot - 2-way sync
by Lucio Godoy 01 May '10

01 May '10

Hi All; I have search the net and i cannot find any answers or fixes for this issue. I have a RHEL5 server running Dovecot Version 1.2.11 all worked well until i have diceded to subscribe to Vodafone's BIS service (BB Bold 9700). Internally I use outlook, and it does 2-way sync without any issues, but the blackberry only syncs new email and it does not sync deleted emails when I delete them in Outlook. Is there any special setting to allow such synchronisation? My server is secured by a pix firewall with ports 993, and 995 open for email sync (Secure IMAP and Secure Pop), i have setup the blackberry to use port 993. Many thanks for your help.

[Dovecot] 1.0.15 --> 1.2.11 --> got too little data
by Andre Hübner 30 Apr '10

30 Apr '10

Hello, did updates from 1.0.15 to 1.2.11 and is in most cases succesful. Sometimes dovecot leaves errormessage in Log: IMAP(username): FETCH [HEADER] for mailbox INBOX UID 5106 got too little data (copying): 516 vs 528 Until now only Inbox was effected and no other folders. I delete cachesfiles in ~mail/.imap to solve this but is there a way to do this automatical (self healing)? Dovecot could recreate complete caches if there was a difference in calculation. Thanks, Andre

[Dovecot] Quota maildirsize and dbox
by luben karavelov 30 Apr '10

30 Apr '10

Hello, Is there any reason that maildirsize Quota store should not work in dbox folders or any other folder based mailbox stores? I have patched a test version here and it seems to work (added "dbox" check in src/plugins/quota/quota-maildir.c line 785). If there could be any complications or unexpected consequences of this setup? Thanks in advance luben

[Dovecot] Expire plugin / expire-tool redesign for doveadm
by Timo Sirainen 30 Apr '10

30 Apr '10

Expire plugin / expire-tool seems annoyingly inflexible currently, so I was thinking about a more generic redesign: The expire plugin keeps track of the oldest message in configured mailboxes. Its only configuration is the list of tracked mailboxes. There's no configuration like what the expire timeouts are or anything. There will be a new doveadm command: doveadm expunge [-u user | -A] <mailbox> <search query> So when you want to expunge all mails from Trash older than 1 week for all users, you say: doveadm expunge -A Trash savedbefore 1w This command works even without expire plugin. To optimize it to avoid looking into all users' Trash mailbox, there's a new expire doveadm plugin, which can use the expire dict to filter out users who don't have anything to expunge. This also supports another feature that the plugin can optimize: doveadm move -A INBOX Archive/2009/INBOX since 2009-01-01 before 2010-01-01 And since people have had problems waiting for expire dict to fill, there could be also a new parameter that does the filling immediately. TODO: - dbox altmove feature will be removed from expire plugin. it may need another plugin, or some other way to configure expire plugin for it. it's anyway a special case. - When using multiple mailboxes it would be more optimal to handle all mailboxes for a user at once, rather than using separate doveadm commands. Maybe the command syntax needs some more thinking to support this. Different mailboxes could have different rules though..

[Dovecot] Released Pigeonhole Sieve v0.1.16 for Dovecot v1.2.11
by Stephan Bosch 30 Apr '10

30 Apr '10

Hello Dovecot users, Pigeonhole development has slowed down significantly in the last few months due to the fact that I got swamped in work. The plan is now to move active development of Pigeonhole to Dovecot v2.0, meaning that this will be the last release for v1.2 that contains significant development changes and new features. However, if a certain new feature is simple enough and there is a demand for it, I may backport it from v2.0 and release it along with any bugfixes that may still arise. The main thing that this new release adds is full support for the spamtest, spamtestplus and virustest extensions. These extensions implement a uniform means of testing the content spam/virus status headers in mail messages: http://ietfreport.isoc.org/idref/rfc5235/ Not many people have tested these new features yet and therefore these are currently considered experimental. Test these thoroughly before you start using them! Documentation is available in doc/spamtest-virustest.txt Changelog Sieve v0.1.16: * Finished implementation of spamtest, spamtestplus and virustest extensions. These are not enabled by default and need to be activated with the sieve_extensions setting. Documentation available in doc/spamtest-virustest.txt + Vacation extension: the from address of the generated reply is now by default equal to whatever known recipient alias matched the headers of the message. If it is one of the aliases specified with :addresses, it is used in stead of the envelope recipient address that was used before. + Restructured and optimized the lexical scanner. + Added --with-docs configure option to allow disabling installation of documentation. - Accidentally omitted 'extern' in two declarations of global variables in header files, causing compile failures on certain systems. - Deprecated imapflags extension: fixed implicit assignment of flags. Turns out this never really worked, but the effect of this bug was obscured by the removeflag bug fixed in the previous release. - Fixed various memset argument mixups in enotify extension. This caused warnings on certain systems, but luckily no adverse effects at runtime. The releases are available as follows: Sieve: http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.16.tar.gz http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.16.tar.gz.sig Refer to http://pigeonhole.dovecot.org for more information. Have fun testing the new releases and don't hesitate to notify me when there are problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Again: Occasional problem with POP3-Download
by Andre Tann 30 Apr '10

30 Apr '10

Hello everyone, in february I posted the mail below[1]. I can now reproduce the problem. When filling up a mailbox with postfix' smtp-source with dozens of identical mails, then it is never possible for me to fetch one single mail out of the mailbox. The process of fetching mail via POP3 always fails. It makes no difference which mail client I use. I have tested KMail, Outlook and Thunderbird. Can anyone confirm this? Is dovecot for some reason unable to deliver such identical mails? Can it be the case that this is a problem with too similar message ids? ~/Maildir/cur$ cat * | grep -i message-id Message-Id: <1024.0003.0008@alphamobil> Message-Id: <1024.0003.0009@alphamobil> Message-Id: <1024.0003.0006@alphamobil> Message-Id: <1024.0003.0007@alphamobil> Message-Id: <1024.0003.0005@alphamobil> Message-Id: <1024.0003.0004@alphamobil> Message-Id: <1024.0003.0003@alphamobil> Message-Id: <1024.0003.0002@alphamobil> Message-Id: <1024.0003.0001@alphamobil> Message-Id: <1024.0003.0000@alphamobil> Thanks and greetings from Munich! AT [1] Hello everyone, I have two mailservers [1] running dovecot. Mail store format is maildir. Every once in a while I have the following problem: When a User downloads his mail via POP3, the client says something like "the server has closed the connection unexpectedly, and gives this reason: [...blahblah...]". One can now cancel the download, and restart it, and the problem shows up again and again. The first few mails get downloaded, and then the process stops. Strange to say the "blahblah"-portion is a piece of text out of the email that doesn't want to get downloaded. Then I remove this single message out of the Maildir/cur-directory, and everything is fine again. It is easy to figure out which mail to delete because it's the first one that is not market as seen [...] filename...:2,S otherfilename...;2, <= this file must be deleted [...] For me it looks as if dovecot had a problem with some byte sequence in this mail, and for some reason it gives an error message to the client which is taken out of the mail. On the SuSE-Machine, before dovecot there was a courier-imapd running, which never showed this kind of problem, so it should not be a client problem. Hopefully my description is clear enough. Does anyone have an idea what's going on here? Thanks. Andre [1] One machine is a openSuSE 11.2 with # rpm -qa | grep dovecot dovecot12-backend-sqlite-1.2.9-0.1.1.i586 dovecot12-backend-mysql-1.2.9-0.1.1.i586 dovecot12-backend-pgsql-1.2.9-0.1.1.i586 dovecot12-1.2.9-0.1.1.i586 The other machine is a Debian Lenny with # dpkg -l | grep dovecot dovecot-common 1:1.0.15-2.3+lenny1 dovecot-imapd 1:1.0.15-2.3+lenny1 dovecot-pop3d 1:1.0.15-2.3+lenny1 -- Andre Tann
