[Dovecot] Read-only mail folders
by Chris Wakelin 24 May '05

24 May '05

Is it possible to have folders on read-only partitions in Dovecot 1.0-stable? We have a NetApp fileserver which would probably be accessed via NFS (though iSCSI is possible) and which stores readonly "snapshots" of every directory accessible as .snapshot (but usually hidden from the operating system). It would be very nice to set up a "snapshot" namespace something like :- namespace public { separator = / prefix = "#snapshot/" location = maildir:%h/Maildir/.snapshot/nightly.0 hidden = yes } so that users could recover messages from say yesterday's version of their mailbox. Unfortunately, Dovecot always seems to want to write to the directory, even when indexes are stored elsewhere (as recommended with NFS anyway, I think) using INDEX=whatever in the location line.

Hi all I just compiled Dovecot v1.0-test70 and i tried using the dovecot-example.conf for a quick test to see if the daemon would work. But I keep getting the following error message in me /var/log/messages: May 17 12:33:46 mail dovecot: Dovecot v1.0-test70 starting up May 17 12:33:47 mail dovecot: Auth process died too early - shutting down May 17 12:33:47 mail dovecot: auth(default): No password databases set May 17 12:33:47 mail dovecot: child 29405 (auth) returned error 89 This is is a section in my conf file. auth default { mechanisms = plain auth_userdb = passwd auth_passdb = pam #auth_userdb = passwd #auth_passdb = pam #userdb = /etc/passwd #passdb = /etc/passwd # passdb pam { # Service name or * as parameter. * means the authenticating service name # is used, eg. pop3 or imap. #args = dovecot # args= /etc/passwd # } # /etc/passwd or similar, using getpwnam() # In many systems nowadays this uses Name Service Switch, which is # configured in /etc/nsswitch.conf. # passdb passwd { # args= /etc/passwd # } # /etc/shadow or similiar, using getspnam().

[Dovecot] Stability
by Casey Allen Shobe 24 May '05

24 May '05

I am currently using Dovecot 0.99.14-r1 as provided by Gentoo, in a Qmail + VPopmail configuration. I am curious as to how to configure it to ensure the most stability, as it serves >1000 clients. I would rather disable any indexing that give small speed improvements if they are not known to be stable. Advice?

[Dovecot] 1.0-stable loses flag changes sometimes?
by Chris Wakelin 24 May '05

24 May '05

I've been struggling with an odd bug in the latest 1.0-stable (20050427) release. Sometimes Dovecot seems to forget that a message has been read or deleted and marks it unread (or not deleted). As far as I've been able to determine, it seems to happen when 1) There have been several recent deliveries 2) Possibly some of those deliveries are of multiple messages 3) Possibly they are read very quickly (say only a second for each message) 4) Folder is an mbox (haven't tried Maildir) I've seen it with Thunderbird mostly, but did manage to recreate it once in "telnet" - the debug IMAP client ;) - using "IDLE" "FETCH" and "STORE msgid +FLAGS (\Seen)" commands. I managed to catch it in the act with one Thunderbird session, and it seemed to occur when Thunderbird, for some reason, issued an IMAP "CHECK" command. In this case it issued an extra "* 710 FETCH (FLAGS (\Recent))" response (the new messages had been msgid 711-715). Incidentally, Thunderbird seems to do a "STORE .. +FLAGS (\Seen)" command even though this is implicit the "FETCH .. BODY[..]" command (and it gets informed of the flag change in the response). I've tried and tried to find a "formula" for re-creating the problem "on demand", but it only goes wrong occassionaly. My guess is it's some sort of timing thing with mbox sync (BTW we have "mbox_dirty_syncs = yes" and "mbox_very_dirty_syncs = no"). Has anybody else seen this? I'm hoping to roll out this version to our wider group of testers soon and would like to get this issue solved first if possible (it counts as an annoyance rather than a serious problem).

[Dovecot] Info request
by Filip Cristian 23 May '05

23 May '05

Hello, I'am Filip Cristian System Administrator at Astral Telecom and i'am using on our email servers dovecot for pop*, imap* auth with mysql suport. I have noticed that in the 1.0-test* release you have support for multiple password databases. From what i have tested this it's working but only if you want to fallback to another supported password databases different that the privios. Is there a posibility to use multiple mysql authentication ? I mean to use two or more mysql hosts on wich to connect and search for the username if the user it's not in the first database? Best regards, -- Cristian Filip Network Administrator Astral Telecom Dostoievski 28, Cluj-Napoca Tel: 0364-100106 Fax: 0264-414688 http://www.astral.ro !DSPAM:4291eb3c217031927099527!

Hi I'm have problems with dovecot and the php imap_open function. Can't seem to get it to work. I just get a "Aborted login [127.0.0.1]" in the dovecot logs. The php error is: [client 192.168.1.254] PHP Warning: imap_open(): Couldn't open stream {127.0.0.1:110/pop3/notls/norsh/novalidate-cert}INBOX in /var/www/html/mail/auth.php on line 89, referer: [client 192.168.1.254] PHP Notice: (null)(): Can't open mailbox {127.0.0.1:110/pop3/notls/norsh/novalidate-cert}INBOX: invalid remote specification (errflg=2) in Unknown on line 0, referer: Same type of error with ether imap or pop3. Anyone have a trick around this? Thanks for any help. Regards Daniel

Hi all I have just finished installing / configuring my dovecot IMAP server. Im seeing something weird happing. It seems my Winblows Outlook users are experiencing a problem whereby when they delete an email, Outlook puts a line though the email, but the mail does not delete. Im not sure if this is a an outlook problem or a dovecot IMAP problem. I cant see anything in the conf file to suggest that it is a IMAP problem. If anyone has any tips or advice, it would greatfully be appreciated. Kind Regards Brent Clark
