I think you need to take your biases and go someplace else. If you don't like MySQL because of some personal bias, then don't use it. Anyone halfway competent can build Dovecot themselves and not rely on some third-party RPM's that have dependencies. This is a discussion list for Dovecot. Please try and stay on topic...

[Dovecot] Headers "missing" in new CVS version
by Todd Burroughs 13 Jul '05

13 Jul '05

We're experiencing an odd problem with dovecot "losing" headers. This started happening with the CVS release as of July 4 and still happens with July 12. It was working properly June 28. It does not happen using pine or thunderbird. It happens using webmail (twig). When you open the inbox, you see subject, etc. When you open a mail, all of the headers are gone. Returning to the inbox, all the headers are missing. It seems to cache this as well. After returning to the older dovecot, all of the headers are missing. Deleting the cache files fixes this and there does not seem to be any mbox corruption. It does not log any errors or crash. Todd Burroughs

[Dovecot] separate SSL certificates for pop3s and imaps
by Michael Weiser 13 Jul '05

13 Jul '05

Hi, I'm migrating a uw-imap installation to dovecot. With uw-imap I had different SSL certificates and keys for ipop3d and imapd. How can I configure dovecot to do the same with its pop3s and imaps services?

[Dovecot] add inotify support to dovecot
by Johannes Berg 13 Jul '05

13 Jul '05

Hi, attached patch against test76 adds inotify support and the --with-notify=... configure option that defaults to the current check for dnotify using no special method if dnotify cannot be compiled, and can be set to none, dnotify and inotify. If it is set to dnotify or inotify, failure to compile a test program results in an error. Also, it adds | file change notification method ..... : <method> to the output at the end of configure. The only thing I don't like about this patch is the fact that I had to add a field notify_context to struct io, but I didn't see a different way to handle this. Also, the patch doesn't support the condition parameter, it simply always asks for all the relevant changes. I don't really see that it is useful for in the context of file system notifications anyway. I modeled this after ioloop-notify-dn.c with my other patch applied to it, if you don't like the other patch you'll want to "revert" that change in the new ioloop-notify-inotify.c file as well. Oh, and obviously I didn't include patches to configure and all the Makefiles, so of course you'll have to run automake. But you already knew that :) I only tested this with maildir. I did add IN_MODIFY so I think it should work with mbox too, but someone should probably verify. Have fun, johannes

[Dovecot] sorting question
by Johannes Berg 13 Jul '05

13 Jul '05

Hi, If I understand the thread sorting algorithm correctly (from draft-ietf-imapext-sort-17.txt and the code), it will sort like this (where I use numbers instead of dates with higher numbers being newer mails) 4 10 3 11 2 12 1 13 etc into all the lower levels. Thunderbird will actually sort this like this: 1 13 2 12 3 11 4 10 where threads are sorted by the newest child in them. Now, I am thinking that evolution simply uses dovecot's THREAD feature and doesn't implement anything itself, so that if I wanted to have that kind of threading, I'd have to implement it in dovecot. Would this be easy? I'm thinking that I should just treat all nodes as if they were dummy nodes in sort_root_nodes, but that only fixes the first level afaict, because later dates are not propagated up. Essentially, I think what the algorithm tb uses does is not use a nodes date as it's sorting criterion, but it's newest child, and apply this rule recursively. Does anyone else think this feature would be useful? I regularly end up almost missing mail because it is sorted at such a low position and I don't see the thread at all.. johannes

[Dovecot] Dovecot runs as ...
by Matt Juszczak 13 Jul '05

13 Jul '05

Hi all, We're using LDAP 100% for everything ... So does that mean that for the following user, I can put another user, like nobody? user = root I guess that user still has to be able to access /var/mail and such, correct?

[Dovecot] 1.0-test77
by Timo Sirainen 13 Jul '05

13 Jul '05

http://dovecot.org/ It's hot in here. Something like 25-30c for many days now. My brains don't work in that heat. So, this is still not an 1.0-alpha1. I'll put it out when I think the release will actually be fully working :) Changes since test76: - Fixes to FETCHing MIME body parts, especially with message/rfc822 attachments. We hadn't been handling this entirely correctly ever (this part of IMAP spec was pretty difficult for me to understand earlier..). This also caused Dovecot to sometimes disconnect clients fetching [n.MIME] body parts earlier, if someone had that problem. - Maildir: Several bugs fixed with APPEND/COPYing mails - mbox: Keywords weren't stored to index with APPEND - inotify patch by Johannes Berg (and possibly broken by me). Can be enabled with --with-notify=inotify parameter to configure. - SEARCH now doesn't fail if a messageset outside valid range is given to it. Some mobile IMAP client was broken because this didn't work. - Cache mail headers when saving mails to mbox. We should cache everything, but this is a start.. - And other cache file fixes/optimizations

[Dovecot] PERMANENTFLAGS bug?
by Nils Henrik Tvetene 12 Jul '05

12 Jul '05

Hi, Im new to the list, so might be a FAQ allthough I havent found it anywhere: When I try to connect to dovecot/imap from snappermail (palm), I get a IMAP protocol error. The complaint is about: OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft ) \*)] Flags permitted. As you can see, theres an extra " )" after "Draft". Any clues on how to fix/bypass this? Regards, Nils Henrik Tvetene

[Dovecot] Dovecot 1.0-stable mbox performance and disconnections
by Chris Wakelin 12 Jul '05

12 Jul '05

I've got some of our busiest users now using Dovecot instead of UW-IMAP with mbox-format mailboxes and predominantly Outlook Express as the client. Doing some perfomance monitoring (with Solaris 8 process accounting), it looks like Dovecot needing to read only 30-50% of the disk blocks needed by UW-IMAP, but I was hoping for better! What seems to happen, is that most of the connections use only a small number of blocks (due to Dovecot indexes, presumably) but occassionally a process will read lots of blocks, sometimes even more than a UW-IMAP session. Is this expected, or is something going wrong with the index updates? I have the default sync settings, I think (mbox_dirty_syncs = yes, mbox_very_dirty_syncs = no, mbox_lazy_writes = yes) My INBOX is an extreme example with ~10,000 messages and most processes reading a few hundred blocks but a couple using 20,000 or so! Also, Dovecot seems to be dropping connections, sometimes, for no good reason (putting some extra i_info lines suggests for "inactivity"). Thunderbird tends to reconnect automatically, though. It seems it may be happening at the end of an IDLE command, something like:- 4 IDLE + idling * 1005 EXISTS DONE * 1005 EXPUNGE but then the expected 4 OK Idle completed never comes. Has anybody else seen this?
