by spart cus 29 Mar '06

29 Mar '06

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? Im using dovecot and postfix for my mails server. tia --------------------------------- Yahoo! Messenger with Voice. PC-to-Phone calls for ridiculously low rates.

[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

We're new to dovecot (and really enjoying its speed and good sense!) We are delivering via exim, not yet using the dovecot-lda, and we are delivering to maildirs, but we don't seem to have any dovecot-uidlist files. What are we missing? Thank you, Marilyn

[Dovecot] dovecot died
by Marten Lehmann 28 Mar '06

28 Mar '06

Hello, today our dovecot imap server died. The following message appeared in the logfile: dovecot: Mar 23 07:00:58 Error: pipe() failed: Too many open files We have one dovecot instance for pop3 and one for imap, so while the pop3-service was still available, the imap-service was not running any more. I've seen a lots of users keeping there imap-connections idle for hours, often more than one per mailbox. How can I limit this? Can I limit the maximum time a connection can be open? Regards Marten

[Dovecot] Re: OS X-centricities? Too many files, temp, indexes, etc...
by Roger Weeks 27 Mar '06

27 Mar '06

We're an ISP with approximately 9000 email customers. Up until early in January our primary mail servers ran on OS X, with exim as the MTA and courier-imap as the pop/imap server. We had continual problems with courier on OS X. The load it generates on the machine is horrible. You'll get absolutely no help from the courier mailing list or developers with OS X issues. When we started evaluating Dovecot, we first attempted it on OS X, however we were unable to get it running in an NFS environement on OS X in any sort of stable manner. I can't recommend highly enough getting off of OS X if you can for mail services. We went to Red Hat machines, and they have been amazingly stable and reliable. I love OS X, and use it for other things, but it makes a bad mail server at least for the volume of mail we process. -- Roger J.
