[Dovecot] Dovecot randomly stops responding
by Miguel Saturnino 18 Jun '06

18 Jun '06

Hi! I'm running Dovecot 1.0beta7 on FreeBSD 6.0 (i386) and it randomly stops responding. To mitigate the problem I made a little ruby scripts which logs in to the POP3 server every 3 minutes and, in case of error (the errors are usually timeout or end of file errors), restarts Dovecot. Although this keeps this keeps things working, I'd like to figure out what is causing Dovecot to stop responding. Looking at the logs, nothing stands out except that there is always one or more of these messages just before Dovecot stops responding: Apr 20 19:25:00 zeus dovecot[62881]: pop3-login: Disconnected: Inactivity: rip=209.123.xxx.xxx, lip=64.21.xxx.xxx Any help debugging this would be greatly appreciated. Thanks, -- Miguel Saturnino <miguel.saturnino(a)teiadigital.pt>

[Dovecot] Maildir++ implementation issues.
by Apps Lists 18 Jun '06

18 Jun '06

Hi Timo and crew! I'm doing more testing with Dovecot and Maildrop today and have run across some strangeness. It appears as if Maildrop stores updates to the maildirquota file in a way that causes Dovecot to ignore them. In my test scenario, Dovecot just rebuilt my maildirsize file to the following: 0S 86213796 108 After delivering a few messages through Postfix -> Maildrop and have the following maildirsize file: 0S 86213796 108 5102 1 387708 1 5093 1 382406 1 3550 1 268337 1 Note the pretty formatting. These are spaces. Unfortunately, Dovecot seems to ignore these when reading the maildirsize file in maildirsize_parse(). It appears to be using sscanf to look for numeric entries: if (sscanf(*lines, "%lld %d", &bytes_diff, &count_diff) != 2) I've read and re-read the maildir++ specification at http://www.inter7.com/courierimap/README.maildirquota.html and can't understand why Maildrop implements things this way.

[Dovecot] asserts and cores in beta3
by Jeff A. Earickson 18 Jun '06

18 Jun '06

My setup: Solaris 9, built with gcc 4.0.2 (I now have gcc 4.1 installed on my system, but have not rebuilt dovecot). A couple of asserts and cores in the last few days: Mar 1 09:25:13 emerald dovecot: [ID 107833 mail.error] imap(tmwillia): file mbox-sync.c: line 1471 (mbox_sync_do): assertion failed: (!sync_ctx->mbox->mbox_sync_dirty || (flags & MBOX_SYNC_UNDIRTY) == 0) Mar 1 09:58:44 emerald dovecot: [ID 107833 mail.error] imap(eewilson): file mbox-sync.c: line 1471 (mbox_sync_do): assertion failed: (!sync_ctx->mbox->mbox_sync_dirty || (flags & MBOX_SYNC_UNDIRTY) == 0) Mar 3 16:18:54 emerald dovecot: [ID 107833 mail.error] imap(tmwillia): file mbox-sync.c: line 1471 (mbox_sync_do): assertion failed: (!sync_ctx->mbox->mbox_sync_dirty || (flags & MBOX_SYNC_UNDIRTY) == 0) Backtraces from the two cores in hand are attached. I can do further poking at the cores if that would help. Jeff Earickson Colby College

[Dovecot] 1.0 beta3 not preserving X-Keyword header?
by Gregory K. Ruiz-Ade 18 Jun '06

18 Jun '06

We've been putting 1.0 Beta 3 through the paces on our test system, and one of our users pointed out to me that Thunderbird's "labels" behave strangely on the new server. In fact, there used to be a header added to the message via IMAP when Thunderbird placed a label on a message, but as of the switch from 0.99.11 to 1.0beta3, this label header is no longer placed in the message. Specifically, Thunderbird adds the "X-Keyword: $LabelN" header when you add a label to the message in tbird, where "N" is [1-9]. This works on dovecot 0.99.11 (RHEL4), but not on 1.0beta3. 1.0b3 doesn't seem to add this header at all, but rather seems to keep this information somewhere else. Perhaps in the .imap indexes? We're using mbox stores on the server. This was tested with both Thunderbird 1.0.7 (most widely deployed) and Thunderbird 1.5. Aditionally, we've found that if the .imap index directories are removed, all the Thunderbird labels on messages seem to get "confused", too. I.e., if the user uses multiple machines throughout the day, changes in one client may not be reflected in another, when the user moves to a different system. I'm still trying to get more details from the users, but have been doing preliminary testing that verifies this. One of the users complaining about this is my manager, who makes extensive use of Thunderbird's "Label" feature, so he's a bit nervous. :\ Another thing we've noticed is the potential for bad behavior if a use switches from the old dovecot to the new dovecot, which seems to be resolved if the .imap indexes are removed... Let me know what other information is needed, and I'll do my best to collect it. Gregory -- Gregory K.

[Dovecot] RHEL 3 and quota problems...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've just installed 1.0beta9 on my RHEL 3 system and am still getting the problems with the quota-fs returning "invalid argument".

by Roy Marples 18 Jun '06

18 Jun '06

Hi List! Attached is a patch to configure.in to test that epoll, poll, inotify, kqueue and dnotify actually work. It also attempts to select the best one for you if none specified. This supercedes my previous patch in the re beta9 thread. Hopefully get this in Gentoo's beta9 ebuild soon.

[Dovecot] Plain and MD5 passwd for the same user?
by M. Fioretti 18 Jun '06

18 Jun '06

Hello, I'm running dovecot 1.0-0_12.beta8. Since I have only a very small number of user on that server, I have their names and password in text files, no databases. imap works both via webmail and via Kmail Is it possible to have, for the same user, a plain unencrypted password when connecting via imap on the local interface (needed, as I understand it, to be squirrelmail compatible) and a DIGEST-MD5 one when connecting via pop3s or imaps remotely? TIA, Marco -- Marco Fioretti mfioretti, at the server mclink.it Fedora Core 3 for low memory http://www.rule-project.org/ We are drowning in information but starved for knowledge. -- John Naisbitt, Megatrends

[Dovecot] Server CommonName mismatch: localhost.localdomain

Hello, I have seen via google that this very problem was already discussed on this and other lists some months ago, but the archives report no solution. I have dovecot 1.0-0_12.beta8 on Centos 4.3. IMAP works just fine: I can read email from both Squirrelmail via web and Kmail. Now I have created an ssl certificate and I'm trying to use it via pop3.

[Dovecot] APPEND command truncates message
by Chris Rodgers 18 Jun '06

18 Jun '06

Hi, I have been debugging a small perl script (see ShowBug2) that I use. In doing so, I think that I may have uncovered a problem with the dovecot IMAP server. Attached are two packet traces for connections to two different IMAP servers. On both servers I run the script: i.e. I login, select a folder, search for messages and append a message. On the fvs5 server (Courier IMAP?), everything works as expected. However, on the dovecot server, the message that is saved into my mailbox has been truncated at the end of the line containing "26". I attach a copy of the saved message in MessageAsOnIMAPServer.txt. I hope that this report might be useful. Please let me know if you require any further information.
