[Dovecot] Sorting a folder (by THREAD) takes a long time
by Asheesh Laroia 30 Aug '08

30 Aug '08

My email workflow with Dovecot is that mail gets delivered to INBOX, where I handle it and then move it into a folder called archive. I have alpine set to use the Default sort of "THREAD" of a folder. After moving a (few) mail(s) from INBOX to archive, archive takes a long time (10-50s) to load while alpine tells me: [Sorting "archive" ... ] (I can do the IMAP traces, but I figure alpine's terminology is going to be so similar to IMAP terminology that it should be straightforward enough for Timo to know what I'm talking about.) I don't actually know enough about Dovecot to say for sure what makes this slow, but maybe it's just indexes not being updated? What might be making this slow, and what hope is there for it being fast? (-: It seems like the really nice thing to do would be, after the save, in the background examine the archive folder and update whatever caches need to be updated. The more work that happens while I'm not waiting, the happier I'll be! (Same goes for my mom, and the other less-technical users of Dovecot.) Is this the kind of thing I could write a plugin for...? -- Asheesh. -- It seems to make an auto driver mad if he misses you.

[Dovecot] Dovecot 1.1.2
by Lauri Jesmin 30 Aug '08

30 Aug '08

Hello, I upgraded dovecot to 1.1.2 this weekend and i get those errors: grep dovecot /var/log/net/maillog |grep Panic | cut -d " " -f 11-100| sort | uniq -c | sort -rn 7547 file index-sync.c: line 39: assertion failed: (seq_range_exists(&ibox->recent_flags, uid)) 89 file index-mail.c: line 1091: assertion failed: (! mail->data.destroying_stream) 18 file mbox-sync-rewrite.c: line 590: assertion failed: (mails[idx].from_offset == start_offset) 5 file ostream-file.c: line 533: assertion failed: ((size_t)ret == total_size || !fstream->file) 5 file mbox-lock.c: line 675: assertion failed: (lock_type == F_RDLCK || mbox->mbox_lock_type != F_RDLCK) 1 file message-parser.c: line 684: assertion failed: (ctx->part->physical_pos >= ctx->input->v_offset) My setup is this: 3 servers, all Solaris, running dovecot, share home directiories via NFS, mbox format mailboxes in home directories. Indexes are separate in every server, not shared via NFS. About 20 000 users total. When old indexes (1.0.15) were present, mailboxes with UID validity problems did not fix themselves, but after i removed index directories in all machines, seems like it started to repair uid validity problems. The first panic seems to be tied to UID validity problems. Some locking problems may be, because i renamed index directory and created new while dovecot was running. -- Lauri Jesmin <lauri.jesmin(a)ut.ee> Tartu Ülikool

[Dovecot] Proxy logging destuser
by Paul Gamble - MWEB 30 Aug '08

30 Aug '08

Hi All My first post to the list, so "hello world"! Having searched the list archives and the wiki for an answer to this, I don't think it is possible. However, let me ask nonetheless... Is it possible for a Dovecot proxy's login process (IMAP and POP3) to include the "destuser", i.e. the uid used to authenticate to the backend IMAP/POP3 server, in its logging? "%u" gives me the uid provided by the client of course, but it would useful for my purposes to catch the "destuser" in the same log line. The only way to get the proxy to log "destuser" at all, as far as I can figure out, is to enable "auth debug" - not something I want to do in a production environment.

[Dovecot] Wishlist: TLS,SSL cipher in a variable.
by R A 30 Aug '08

30 Aug '08

Hello again. Just thought I'd ask and see if it would be possible to get this sometime in the future: TLS and SSL connection information in a variable like %c today, but more exhaustive. For example I can from postfix get a log like: postfix/smtpd[432]: Anonymous TLS connection established from xxxxxx: TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits) This would be nice to see if you have a fairly low permissive level, to identify potential weak clients and be able to notify these to start with while still allowing connections. -Roger

[Dovecot] Problem with squirrelmail and dovecot 1.1
by Gerhard Wiesinger 30 Aug '08

30 Aug '08

Hello! Has noone any idea? Ciao, Gerhard -- http://www.wiesinger.com/ -------------------------------------------------------- Hello! I'm running squirrelmail 1.4.8 (I know this is not the latest version) and know I'm having troubles with: 1.) Folder list view 2.) Save to sent or Drafts folder. Configuration worked well. I think it has to do with the upgrade from dovecot 1.0 to 1.1 and the LIST command. Thunderbird/alpine work well. Commands from rawlog are: A002 LIST "" "~/Mail/Drafts" A002 OK List completed. or A002 LIST "" "~/Mail/sent" A003 CREATE "~/Mail/sent" A002 OK List completed. A003 NO Mailbox exists. Has something changed in the folder behaviour of dovecot from 1.0 to 1.1? If you need more information please let me know it. Any ideas? Thnx. Ciao, Gerhard -- http://www.wiesinger.com/

[Dovecot] mailbox lock
by Thiago Monaco Papageorgiou 30 Aug '08

30 Aug '08

Hello! I need to use my lock method into the dovecot to block a mailbox. I am using maildir format, is there an API that I can implement? I need it because there are others systems which already use my lock method. Best regards. -- Thiago Monaco Papageorgiou <thiago.monaco(a)corp.terra.com.br> ________________________ Terra Networks Brasil S/A Tel: +55 (51) 3284-4274

[Dovecot] maildir, zlib and mtime/internal date
by Richard Platel 29 Aug '08

29 Aug '08

On the wiki: http://wiki.dovecot.org/Plugins/Zlib I think there should be a step 5.0. along the lines of "get and remember the original message file's mtime" And a step 5.4 like "Using the touch command or some other method, set the now compressed message's mtime back to the mtime of the original message file." To preserve the message's internal time in case the indices ever get rebuilt. Does this sound right?

[Dovecot] Sieve fileinto a subfolder fails
by Rich McAllister 29 Aug '08

29 Aug '08

I'm using Dovecot 1.0.10 on Ubuntu 8.04, using the packages from the distro; exim4 is my MTA and it's configured according to the instructions in the wiki, everything is working fine for delivery into the Maildir INBOX via Dovecot's LDA and reading mail via IMAP using Thunderbird. My habit on previous mail systems was to create a Lists folder and subfolders under Lists for each mailing list I subscribe to. I tried to use Dovecot sieve to sort mail into the folders with sieve filters like require "fileinto"; if header :contains "Subject" "[NCCC]" { fileinto "Lists/NCCC"; } else { keep; } I created Lists/NCCC via Thunderbird (so I could set the "check this folder for new mail property") but when Dovecot tries to deliver into the folder, I get the log message msgid=<...>: Couldn't open mailbox Lists/NCCC: Invalid mailbox name If I use just fileinto "NCCC"; it works fine, going into a NCCC folder not in a subfolder as expected. Is there some other syntax for specifying folder/subfolder names in Dovecot sieve, or do I just have to live with the folders all at the top level? Rich dovecot -n shows: # 1.0.10: /etc/dovecot/dovecot.conf log_timestamp: %Y-%m-%d %H:%M:%S login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login mail_privileged_group: mail mail_location: maildir:/arda/export/mail/%u/Maildir auth default: passdb: driver: pam userdb: driver: passwd
