[Dovecot] LDA bouncing mails after upgrade -- again
by Milan Holzäpfel 09 Sep '07

09 Sep '07

Hi Timo, some time ago (2007-03-24 and following) I asked whether it was intended that Dovecot deliver bounces mails (by terminating with status 89) if the deliver version is older than the rest of the dovecot installation. You replied that it was a bug, and that it had been fixed in <URL:http://dovecot.org/list/dovecot-cvs/2007-March/008346.html>. When I upgraded from Dovecot 1.0.2 to 1.0.3 a few days ago, I found out that this problem probably still exists: | Aug 28 09:38:03 host.example.org deliver(user(a)example.org): Module is for different version 1.0.3: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Aug 28 09:38:03 host.example.org postfix/pipe[18356]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=0.4, delays=0.13/0.09/0/0.18, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") The error message I posted in march was: | Mar 22 20:29:20 host.example.org deliver(user(a)example.org): Module is for different version 1.0.rc27: /usr/lib/dovecot/lda/lib10_quota_plugin.so | Mar 22 20:29:20 host.example.org postfix/pipe[17344]: <ID>: to=<user(a)example.org>, relay=dovecot, delay=1.9, delays=1.5/0/0/0.35, dsn=5.3.0, status=bounced (Command died with status 89: "/usr/libexec/dovecot/postfix-deliver/deliver") I suppose you still want to fix it. Regards, and thanks for all your work, Milan -- Milan Holzaepfel <mail(a)mjh(d)name> <URL:http://mjh.name/> pub 4096R/C790FC23 EB8E 5E81 81E3 53A9 9B74 B895 5179 54C0 C790 FC23

[Dovecot] processing Dovecot maildirs with shell scripts
by M. Fioretti 09 Sep '07

09 Sep '07

Hello, I have a postfix server which uses procmail as its delivery agent to deliver incoming messages to several maildirs. For several reasons, not really relevant here, I need to process/refilter/sort again the content of these mailboxes before delivering the messages to the _other_ maildirs which Dovecot sees and serves to local or remote imap users. Basically, I need to write some shell scripts that, from cron jobs, regularly do this: foreach file in some_incoming_mailbox/new/ do #process the file and/or set some variable according to its content delete the file or mv it to some_other_maildir/new/ where the actual action and value of some_other_maildir is set every time by the "process the file" part of the script. The part that I still miss is guidelines to do these things safely, that is without losing or corrupting messages or doing anything else that would confuse dovecot. For example, under which conditions it is sure to move or delete (the Unix way, with mv or rm) a message from mailbox1/new/ to mailbox2/new, when the latter is served via dovecot to remote users? What is advisable and most efficient? Use locks (how?), only work on file which are at least one minute old? Should I move the messages to tmp instead of new? What else? Tips or pointers about this are very welcome. Ciao, Marco

[Dovecot] Index and Thunderbird
by Jon 09 Sep '07

09 Sep '07

Hi, Whitbox Linux 3 (RHEL) Dovecot 1.0.rc29 Using NFS From time to time does all mail get re-downloaded to Thunderbird. I would believe this has something to do with an index problem. I upgraded to 1.0 a few months ago but that didn't work well so I installed version 1.0.rc29 which worked better but we still get this problem from time to time. DOes anyone know if it is a good idea to install 1.03 or perhaps 1.1alpha? dovecot: Sep 01 04:47:30 Error: IMAP(XXXXXX): rename(/mail2/home/XXXXXX/.Maildir/.Sent/dovecot-uidlist.lock,

[Dovecot] passing quota to deliver via command line
by bill-dovecot＠carpenter.ORG 09 Sep '07

09 Sep '07

Is there any way to pass things like "quota=" for the quota plugin to the deliver LDA via the command line or as an environment variable or whatever? I've got all the info I need in my MTA to avoid a userdb lookup in the LDA, but I still have to do the userdb query to get the per-user quota number (the default quota works fine, of course). -- bill-dovecot(a)carpenter.ORG (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3

[Dovecot] passdb/userdb args
by Daniel L. Miller 09 Sep '07

09 Sep '07

I'm a bit unclear on these - give me a moment to ramble on. I should mention I'm using version 1.0.3, my primary backend is LDAP, and I do NOT want to store user mail folders in my LDAP directory. I currently have the following: default_mail_env = maildir:/var/mail/%d/%n passdb ldap { args = /etc/dovecot/dovecot-ldap.conf } # Instructions for deliver state a userdb is still required if using prefetch userdb ldap { args = /etc/dovecot/dovecot-ldap.conf } userdb prefetch { } My dovecot-ldap.conf is pretty simple - the trimmed version is: hosts = localhost auth_bind = no user_attrs = %d/%n=mail user_filter = (mail=%u) pass_attrs = (&(userPassword=password)(mail=%u)) user_global_uid = 5000 user_global_gid = 8 I recognize that the pass_attrs is incorrect for a prefetch config - but I couldn't get it to work. My mail folder structure is /var/mail/domain/username. If, under 1.0.3, I can't use the %d/%n variables to build the user/home/mail parameters in the LDAP config, can I do it in the configuration stanza? Something like: passdb ldap{ args = home=%dn/%n mail=%d/%n /etc/dovecot/dovecot.conf } -- Daniel

[Dovecot] Timeout while waiting for lock for transaction log file
by Peter Eriksson 09 Sep '07

09 Sep '07

I have a user that gets client timeout errors when he tries to delete/clean up his massive "Spam" folder (many thousands of mail messages). He uses Thunderbird and has it configured to use "Move to Trash" when he deletes messages. I find the following in Dovecot's log file when it happens: Aug 28 10:38:22 ifm.liu.se dovecot: [ID 107833 mail.error] IMAP(bpn): Timeout while waiting for lock for transaction log file /home/bpn/Maildir/.Trash/dovecot.index.log Aug 28 10:38:24 ifm.liu.se dovecot: [ID 107833 mail.info] IMAP(bpn): Disconnected Any suggestions on what I can tuned/fix in Dovecot to solve this issue? We're using Dovecot 1.0.3 with Maildirs. This is the only user (so far) where we are seeing this. - Peter

[Dovecot] BUG REPORT - Stops logging after sleep
by Bruce Bodger 09 Sep '07

09 Sep '07

Version: dovecot --version: 1.0.0 OS: OS X - 10.4.9 Architecture: G5 Dual/1.8Ghz Had a fairly normal time correction last night: May 9 20:56:56 G518X2 ntpd[219]: time set -1.212733 s Which dovecot duly noted: May 9 20:56:56 G518X2 dovecot: auth(default): Time just moved backwards by 1 seconds. I'll sleep now until we're back in present. This morning all of the dovecot processes are running fine but dovecot has stopped logging. (I have modified nothing in dovecot.conf relative to logging: dovecot logs to syslog using the "mail" syslog_facility.) ps -aux | grep dovecot root 53 0.0 -0.0 27772 544 ??

S 7:17AM 0:00.03 imap-login I am starting dovecot via OS X's launchdaemon facility thus the "-F" command line switch requirement. Sending a "kill -HUP" to the process did not get it to start logging.

[Dovecot] trouble with deliver in 1.0.4
by Jack Bailey 09 Sep '07

09 Sep '07

Ok, here's one for the idiot file. I just installed dovecot-1.0.4 on my personal system for testing, a system which has to be the simplest dovecot configuration possible. deliver is barking about something with which version 1.0.3 has no problem. I looked over the wiki, googled, and see nothing wrong. The error: deliver(jjb): Sep 07 21:39:40 Fatal: Failed to create storage for 'jjb' with mail 'mbox:/HOME_DIRECTORY_USED_BUT_NOT_GIVEN_BY_USERDB/:INBOX=/var/mail/jjb' In dovecot.conf: userdb passwd { # [blocking=yes] - By default the lookups are done in the main dovecot-auth # process. This setting causes the lookups to be done in auth worker # processes. Useful with remote NSS lookups that may block. # NOTE: Be sure to use this setting with nss_ldap or users might get # logged in as each others! #args = args = blocking=yes } and mail_location = mbox:~/:INBOX=/var/mail/%u Clues generously accepted, Jack
