[Dovecot] Distributed indexes, maildir_copy_preserve_filename, and Microsoft
by Jack Stewart 30 Aug '08

30 Aug '08

Hi, I've just completed a migration from Courier to a Dovecot 1.0.7 (patched RHE 5) which is working great, except for this weirdness of an issue that is impacting a handful of users. My question is that will turning off maildir_copy_preserve_filename help or hurt in a situation where there are multiple servers with their own local INDEX files (uidlist is shared)? The problem is that a few users on a few versions of Microsoft Mail clients are not showing a few messages. They can see the messages just fine in webmail and other, more typical, E-mail clients. I know that the right solution is to upgrade to 1.1.2 and use shared indexes. The plan is to upgrade in a month or so. In my defense, this setup was not of my making, The two things issues that might have an impact are that we have shared (NFS) maildirs on multiple servers with their own local indexes and maildir_copy_preserve_file turned on. The uidlist (CONTROL) is shared and we have sticky connections turned on in our load balancer. The vast majority of clients do not have this issue. Quite frankly I have no idea these clients are ignoring the dovecot-uidlist. Would turning off maildir_copy_preserve_filename help with this setup? Another option might be easier is to delete the users INDEX and let the clients rebuild them. Since this is only a handful of users and we are migrating to 1.1.2 anyway, my preference is to make the bare minimum of changes to help address this problem. The changes need not be perfect nor anytime more than a suggestion or preference. I just want to make things better for a little while. Many thanks in advance. ---Jack P.S. The performance improvement is amazing - anywhere from 2X to 12X depending on what metrics you are looking at. It isn't an apples to apples comparison since we upgraded the servers as well but the "old" servers are pretty powerful beasts. -- Jack Stewart jstewart(a)caltech.edu / 626-395-4690 http://www.imss.caltech.edu

[Dovecot] sieve forward/redirect to multiple addresses
by Anil 30 Aug '08

30 Aug '08

How can I do this with Sieve? I have a script like this: if header :value "ge" :comparator "i;ascii-numeric" ["X-Spam-Score"] ["25"] { discard; stop; } elsif header :value "ge" :comparator "i;ascii-numeric" ["X-Spam-Score"] ["5"] { fileinto "Junk"; stop; } else { redirect "user(a)test.com"; redirect "user(a)example.com"; keep; } Only the first redirect seems to be honored, the 2nd is not. The only other alternative I see is that I have to create an alias that contains those two addresses, and then I redirect to that alias -- but I would prefer if I can do this through sieve itself. Thanks very much, sorry this is not Dovecot question... but this is on a Dovecot mail server. :)

[Dovecot] sparc quota bug
by dovecot＠lechtermann.net 30 Aug '08

30 Aug '08

Hi, I am getting the following error: dovecot: Jul 23 18:04:44 Error: child 7600 (imap) killed with signal 10 How to reproduce: Try to delete or move a mail to another folder. The mail actually gets copied to the other folder but the original isn't removed (when using webmail). If using thunderbird this ends up in an infinite loop creating new mails in the destination folder (without deleting the original) until stopped manually. When turning off quota or commenting out the "quota: dirsize:storage=1048576" entry it works, just no quotas anymore. :-( Details: OS: OpenBSD ARCH: sparc64 FS: ffs Dovecot version: 1.0.15 and 1.1.1 If you need more information, please let me know. @timo: I could provide access to a OpenBSD sparc64 box if it would help debugging the problem.

[Dovecot] Deliver autocreate with auto-subscribe?
by Paul Reilly 30 Aug '08

30 Aug '08

Hello, I'm using dovecot with postfix configured for address extensions, so email to me+folder(a)mydomain.com <me%2Bfolder(a)mydomain.com>, automatically is handed off to dovecot deliver, which sees there is no folder called "folder" and autocreates it. This is brilliant, as it means I can give out subject orrientated email addresses, and the mail is automatically put in the right mailbox :) I love dovecot with postfix. However, my problem is my IMAP client (roundcube and HordeIMP) does not see the newly created folder. I have to manually subscribe it in the webmail client, or I have to add the folder to the "subscriptions" file in my home dir. So my question is, can the deliver command which auto-creates this folder, also add it to the subscriptions file? It seems like it just needs another switch on the command line. http://wiki.dovecot.org/LDA Is this currently possible, and if not, what code do I need to hack to make it work? Thanks Paul

[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

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/
