[Dovecot] sig11 with 1.0.beta3 on openbsd-i386
by David Gwynne 30 Mar '06

30 Mar '06

i recently helped a friend of mine migrate from imap-uw using mboxes to dovecot on top of Maildirs and came up against two issues. this is quite embarrassing as ive been claiming dovecot is Solid As A Rock(tm) and hasn't ever given me any issues. 1. if dovecot runs out of file descriptors it will loop forever trying to open new logging pipes. the code in question is at line 624 of src/master/login-process.c 2. we get a sig11 in the imap process. heres the bt: dlg@mail dlg$ gdb -c imap.core /usr/local/libexec/dovecot/imap GNU gdb 6.3 Copyright 2004 Free Software Foundation, Inc.

[Dovecot] Realm Stripping
by Michael Baird 30 Mar '06

30 Mar '06

I saw some discussion on this from the middle of last year. Looking through the archives, there didn't seem to be a full solution using a standard dovecot configuration. Did this issue get resolved within dovecot? Will it strip domains from the login presented by the customer. I currently am using dovecot for imap with a webmail system (I strip the domain there before it hits dovecot), but I'd like to replace qpopper with dovecot's pop3, just need to work out the domain stripping bit. Regards Michael Baird

[Dovecot] Solution to Dovecot-lda configure problem on RHEL4/FC4
by Tomi Hakala 29 Mar '06

29 Mar '06

Hello, After a long break from Dovecot I finally managed to compile Dovecot-lda on RHEL 4 x86_64 platfrom. For some reason $LIBICONV translates to a @LIBICONV@ on config.status which generates loop for sed. Solution is to manually edit "configure" after autogen.sh. In configure change line s,@LIBICONV@,$LIBICONV,;t t to s,@LIBICONV@,,;t t After this configure finishes succesfully. Tomi

[Dovecot] [PATCH] integrate dovecot LDA into dovecot
by Timo Sirainen 29 Mar '06

29 Mar '06

(ops, messed up the first send, again) > what do you think about replacing the deliver source in dovecot with > deliver from dovecot LDA? It would make it much easier to compile and > deploy dovecot LDA. It would, but I don't want that, at least not currently. My plan is to merge them in some way at some point, but the Sieve code will always be kept out of the main Dovecot tarball as some kind of plugin. The Sieve code is something I don't really want to touch myself, and I don't want it to be included in Dovecot's "1000 EUR for security hole" competition (or whatever it should be called). Since the patch was a bit too large, I didn't accept your original mail to the list.

[Dovecot] new mails don't always show
by Bjoern Rost 29 Mar '06

29 Mar '06

Hi, I am having some trouble with dovecot (0.99.14) and maildir. Some users are reporting that sometimes, they don't get (pop3, various clients) new mails for a while even though they should. I checked and confirmed this: mails were delivered by MTA (sendmail, procmail). But when the problem existed, the new mails were in cur/, not new/ and dovecot would not report any new messaged to the client. A 'solution' was to send another mail to the same account, and ususally this would end up in new/ On the next fetch, this new message and the new ones from cur/ are downloaded. I also had the same problem with imap and evolution today. My inbox showed as empty but there were many messages in cur/ I could access all other folders without a problem during this period. Again, a simple mail to myself 'solved' this. This behaviour does not happen all the time and I don't know how to trigger/reproduce it. Just the relevant (imho) parts of dovecot.conf: login_process_size = 256 login_processes_count = 64 login_max_logging_users = 1024 default_mail_env = maildir:%h/Maildir client_workarounds = outlook-idle oe6-fetch-no-newmail outlook-pop3-no-nuls everything else is set to default values Any ideas/help?

[Dovecot] Too many links
by Feraudet Cyril 29 Mar '06

29 Mar '06

Hi all, I've a problem during a big migration to dovecot. I'm not sure that is a really a dovecot bug ... but maybe somebody here know one solution ... I have more than 150000 imap account to migrate from an obscure mail system based on a database to an imap/dovecot system. During the migration (simple but very long process) I get a "Too many links" error from dovecot. This error is not obscure but I'm unable to find a solution with this error on google. I kown the /proc/sys/fs/file-max for increase the number of open file, but it's not the problem here. This probleme occure with more than 130000 directory and more than 350000 file. Have you an idea ? Thank, Cyril Feraudet

Hi to All Gurus, Im having some problem with my mail server. Sending works perfectly but the problem is when my clients are receiving theyre mails. For example theyre downloading 20 mails, somehow when it reaches to 12 it disconnectes. Or the outlook client pops up some messages saying connection timeout?

[Dovecot] Problems with Fedora core 5, Dovecot and Thunderbird
by Robert Hart 29 Mar '06

29 Mar '06

Hi I am testing FC5 before upgrading my main server and I am getting errors with dovecot 1.0 beta3 - both the distributed RPM and also the one at ATrpms thunderbird (the distributed version which is thunderbird-1.5-6) I am running both dovecot and thunderbird on the same machine, pointing thunderbird at 127.0.0.1 for its imap server. The symptoms are an inability to access mail - thunderbird just keeps on trying and getting nowhere and even if I shut down thunderbird on the client, it still leaves processes running that have to be killed by hand. In the maillog I get Mar 29 09:17:25 bree dovecot: imap-login: Login: user=<hartr>, method=plain, rip=::ffff:127.0.0.1, lip=::ffff:127.0.0.1, secured Mar 29 09:17:25 bree dovecot: imap(hartr): mbox sync: UID inserted in the middle of mailbox /var/mail/hartr (8 > 1, seq=2, idx_msgs=4) Mar 29 09:17:25 bree dovecot: imap(hartr): file mbox-sync-update.c: line 55 (mbox_sync_move_buffer): assertion failed: (ctx->mail.offset + ctx->mail.space <= ctx->hdr_offset + pos || ctx->mail.offset > ctx->hdr_offset + pos + have) Mar 29 09:17:26 bree dovecot: child 14242 (imap) killed with signal 6 When I point this thunderbird at my main (dovecot 0.99) server everything is fine, we seems to suggest that this is a dovecot problem and not a thunderbird one. Can anyone give me any pointers on this please as it's a show stopper for upgrading my main server. Tks -- Robert Hart hartr(a)interweft.com.au +61 (0)438 385 533 http://www.hart.wattle.id.au
