[Dovecot] needing UNSELECT to notice new mail?
by Greg Troxel 24 May '07

24 May '07

I am running NetBSD/i386 3.1ish and 4.0ish dovecot 1.0.0 procmail delivering into maildirs gnus from CVS head emacs 21.4 thunderbird 2 gnome mail-notification 4 configured to required SSL. Basically everything works fine except that in gnus typing 'g' in the *Group* buffer, which is supposed to check for new mail and list the number of new messages, fails to notice new mail. Notably, gnus does not do an UNSELECT or CLOSE when it is done with a group. So basically the following sequence of commands SELECT "INBOX" blah blah EXPUNGE STATUS "INBOX" shows no unseen but really there is one With (setq nnimap-need-unselect-to-notice-new-mail t) gnus will do UNSELECT before STATUS, and then things work fine. Another gnus user reports what seems like the same problem with Courier IMAP. So, is dovecot complying with the IMAP spec here? Is there some notion of a transaction bracketed by SELECT/{UNSELECT,CLOSE}, and is that using something like READ COMMITTED isolation so that it doesn't see messages added by other transactions? Or should dovecot be not relying on cached state and revalidate the mailbox on STATUS, even if it is already SELECTED? Further, is it the group's opinion that a well-behaved client would UNSELECT or CLOSE when the user takes an action that indicates being finished with a mailbox? Or is it reasonable to leave a mailbox SELECTed as an optimization. It seems that for Thunderbird, etc., the user sits in INBOX with IDLE, but with gnus I tend to be in *Group* with no mailboxes selected.

Hello, I recently saw these errors in my log, and one of my users complained that Dovecot disconnected him unexpectedly.

[Dovecot] Timeout while waiting for shared lock for index file /var/mail/XXX/Maildir/dovecot.index
by Giannis Zachariadis 24 May '07

24 May '07

Hello, I'm using dovecot v1.0rc23 for about 500 users since february with no particular problems. I'm using Maildir format and ldap authentication. A recently added user can't check his mails any more. In the logs I get May 23 14:35:58 mailsrv deliver(XXXX): [ID 702911 mail.error] Timeout while waiting for shared lock for index file /var/mail/XXXX/Maildir/dovecot.index The user connects with IMAP to retreive his mails. Currently I can login to his account with pop3 and retreive the mails, but when it comes to IMAP I get this error and no mail at all. thanks in advance, -- giannis.

[Dovecot] Updated v1.1 and summer plans
by Timo Sirainen 24 May '07

24 May '07

Webmail.us will be sponsoring my Dovecot development for this summer. Other companies are also welcome to participate in the costs. Participation gets you: - listed in Credits in www.dovecot.org - listed in AUTHORS file - you can tell me how you want to use the feature and I'll make sure that it supports it (within reasonable limits) For already implemented v1.1 features, see http://www.dovecot.org/list/dovecot/2007-April/021974.html Some of those features require some more testing (new SORT and THREAD code especially) and a bit of fixes to mailbox list indexes. Otherwise I think it's working pretty well already, I've been using it for a long time for my own mails. Upcoming v1.1 features, more or less implemented in this order: - Index file optimizations: http://www.dovecot.org/list/dovecot/2007-May/022591.html - Less indexing for POP3 users (both in pop3 and in deliver) - Replace Squat FTS indexes with my new design - Configurable mail_log plugin - Limit number of connections for a user - A combined LIST + STATUS command (or possibly NOTIFY extension? http://tools.ietf.org/html/draft-gulbrandsen-imap-notify-03) - Fully supported shared mailboxes and IMAP ACL extension: http://www.dovecot.org/list/dovecot/2007-April/021624.html - Remote (shared) mailboxes. Automatic proxying, but possibly also support for MAILBOX-REFERRALS extension if it's not much extra trouble (few clients support it, so probably not worth the trouble unless it can be done in a couple of hours) - Remove unused keywords from mailboxes - Some other small things Upcoming v1.1/v1.2/v2.0 features (planned to be implemented at the end of the summer): - virtual mailboxes: http://www.dovecot.org/list/dovecot/2007-May/022828.html - dbox redesign: http://www.dovecot.org/list/dovecot/2007-May/022602.html Implementing the above features will keep me busy for most of the summer, but there have also been requests for replication support (http://www.dovecot.org/list/dovecot/2007-May/022792.html) I'm interested in implementing it as well, but unfortunately it looks like I don't have time for it at least for the next 3 months or so. There's already at least one company that's willing to pay for replication, but if you're also interested please let me know. Perhaps someone else could implement it instead (if you're interested, please let me know), or if not it'll just have to wait until I have time for it.

[Dovecot] Old style qouta to new style convert?
by Mart Pirita 24 May '07

24 May '07

Tere. I'm using Debian, postfix & dovecot, with system quotas and settings in dovecot.conf: default_mail_env = maildir:%h/Maildir:INDEX=/var/spool/dovecot/index/%u:CONTROL=/var/spool/dovecot/control/%u But if system quota is full, users won't get new messages but won't get also any kind information, and also in mail.log is nothing. Is this normal? Should I use dovecot -s own quota with postfix or dovecot own LDA is needed? And how to convert these index and control files into users homedir? Just making changes in dovecot.conf seems not be good idea? Or it is and the control and indexes will be created again? -- Mart

[Dovecot] Courier migrating issues: indexes, maildirsize, update query
by Jan van den Berg 24 May '07

24 May '07

Hi, (my first post to the list) I'm in the process of testing Dovecot to see whether it meets our needs to replace our current Courier setup which serves well over 100.000 mailboxes (pop3 and imap: mysql with NFS) So far dovecot seems pretty straight forward; however I ran into a couple of things that I'm curious about. 1. What's the deal with dovecot.index/dovecot.index.log/dovecot.index.cache. I understand Dovecot uses this for POP3 primarily but this will no doubt cause a lot of overhead on our platform. Also getting this to work with our NFS setup would be a pain (locking etc.). I've been following this discussion: http://www.dovecot.org/list/dovecot/2006-January/thread.html#10758; and it ends with C. Malony suggesting that an disable index option would be in place; but no further action is taken. Basically I want to get rid of the index files (courier also doesn't use any). Any suggestions; will there be a disable-index option? 2. One of the reasons we want to get rid of Courier is because the maildirsize is often incorrect. Whether this is because of a bad Courier implementation or NFS issues or whatever, I haven't figured out yet. But I'd like to test this function in Dovecot; but there seems to be very little documentation. I read the link http://wiki.dovecot.org/Quota/Dict but this info is too scarce. Any pointers on where to go? 3. In our MySQL setup we have a field with the latest poptime and pophost (IP). This info can come in handy when troubleshooting or filtering out inactive mailboxes. With our Courier setup this field gets updated by a rather elaborate script that checks the logs and runs updates queries. I could get this to work for Dovecot; but with Dovecot being more actively in development, I wonder could this be a feature; like after a user_query, another update query? Cheers, Jan

[Dovecot] May 21 09:13:14 mail dovecot: imap-login: No authentication sockets found
by dhottinger＠harrisonburg.k12.va.us 23 May '07

23 May '07

I started getting this message this morning: May 21 09:13:14 mail dovecot: imap-login: No authentication sockets found Ive been runing dovecot on a fc6 dell poweredge 2950 for about 4 weeks now with no issues. Im authenticating against openldap 2.3.27. It appears ok. I restarted ldap, and dovecot, and everything looked fine for a few minutes, then this started again. I have around 720 users. Is there a setting in the dovecot.conf that I can use to fix this? Or is the problem elsewhere? -- Dwayne Hottinger Network Administrator Harrisonburg City Public Schools
