[Dovecot] dsync and pop3 migration plugin fails for large inbox due to idle timeout
by Nikolai Schupbach 08 Aug '12

08 Aug '12

Timo, There is a problem with the dsync POP3 migration plugin when syncing a large INBOX. What happens is dsync establishes a connection to the POP3 server at the beginning of the sync, but then it sits there idle until it's used to sync the UIDLs. On a very large inbox with many thousands of messages it will be idle for longer than a POP3 server's idle timeout setting. When the UIDL sync occurs dsync produces the following errors (because the connection has been lost due to the POP3 server's inactivity timeout): dsync(first.last(a)test.co.nz): Error: pop3c(pop3.test.com): Server disconnected unexpectedly dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 13: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 15: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 16: Disconnected ... dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14492: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14493: Disconnected dsync(first.last(a)test.co.nz): Error: pop3_migration: Failed to get header for msg 14494: Disconnected Also at the end of the dsync it actually has an exit status of 0, but it shouldn't because the POP3 sync failed, and none of the UIDLs are retained. Dsync should try to keep the POP3 connection alive, by sending a regular 'NOOP' command to the POP3 server, or it should simply reconnect if sees the connection is lost. At the moment the only work around is to increase the POP3 server's idle timeout to a multi hour value, which isn't a good work around as it causes a lot of inactive POP sessions to bank up. Regards, Nikolai.

The problem is solved!!!! In the library "src/lib-sieve/plugins/vacation/cmd-vacation.c", in the package "dovecot-sieve" or "dovecot-pigeonhole" modify: smtp_handle = sieve_smtp_open(senv, reply_to, NULL, &f); smtp_handle = sieve_smtp_open(senv, reply_to, reply_from, &f); You can check the correct operation in your logs. /var/log/maillog postfix/smtpd[27112]: connect from smtp.mydomain.com postfix/smtpd[27112]: A95D2168456: client=smtp.mydomain.com postfix/cleanup[27114]: A95D2168456: message-id=<A5BBC98AAF65424CADBFB6ACF0003E8B03FB4B74(a)example.com> postfix/smtpd[27112]: disconnect from smtp.mydomain.com postfix/qmgr[17010]: A95D2168456: from=<asier.cidon(a)example.com>, size=7274, nrcpt=1 (queue active) postfix/pipe[27115]: A95D2168456: to=<asier.cidon(a)mydomain.com>, relay=dovecot, delay=0.09, delays=0.01/0/0/0.08, dsn=2.0.0, status=sent (delivered via dovecot service) postfix/qmgr[17010]: A95D2168456: removed /var/log/dovecot.log dovecot: auth(default): master out: USER 1 asier.cidon(a)mydomain.com uid=xxx gid=xxx quota_rule=*:bytes=524288000 home=/buzon/asier.cidon dovecot: deliver(asier.cidon(a)mydomain.com): sieve: msgid=<A5BBC98AAF65424CADBFB6ACF0003E8B03FB4B74(a)example.com>: sent vacation response to <asier.cidon(a)example.com> dovecot: deliver(asier.cidon(a)mydomain.com): sieve: msgid=<A5BBC98AAF65424CADBFB6ACF0003E8B03FB4B74(a)example.com>: stored mail into mailbox 'INBOX' /var/log/maillog postfix/pickup[17009]: B221D168458: uid=xxx from=<asier.cidon(a)mydomain.com> postfix/cleanup[27114]: B221D168458: message-id=<dovecot-sieve-1344420404-703760-0(a)mda.mydomain.com> postfix/qmgr[17010]: B221D168458: from=<asier.cidon(a)mydomain.com>, size=661, nrcpt=1 (queue active) postfix/smtp[27195]: B221D168458: to=<asier.cidon(a)example.com>, relay=smtpinterno.mydomain.com, delay=0.04, delays=0.01/0/0.01/0.01, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as A3A092280B3) postfix/qmgr[17010]: B221D168458: removed

[Dovecot] doveadm import is always verbose
by Jürgen Obermann 08 Aug '12

08 Aug '12

Hello, with dovecot versions up to 2.1.9, when I use: doveadm import -u guser mbox:/tmp/mbox/guser/restore_2012-05-08 restore_2012-05-08 all it always sends out info messages for every mail copied like that: doveadm(guser): Info: copy from mymail: box=restore_2012-05-08/mymail, uid=5, msgid=<######>, size=6999462 I had expected to see these info messages only if I add the verbose option to doveadm. And using the option -v with: doveadm -v import -u guser mbox:/tmp/mbox/guser/restore_2012-05-08 restore_2012-05-08 all makes no difference at all, the same messages appear. The verbose option seems to be always on. Is this a bug or intended behaviour?

[Dovecot] Dovecot with Company - level Quota
by Kavish Karkera 08 Aug '12

08 Aug '12

Hi Timo, We are using maildir as quota-backend , and performing user level quota, which is working fine. (using dovecot 2.x ). Now the requirement is to , restrict the quota to client / company level along with user level quota. For. eg. We have a mailbox path like /mail/mailstore/10001/kavish.karkera(a)linoquery.com/Maildir/ where 10001 is Client code (unique number given to very client) instead of domain name. So there would be two quota's one at company level and other user level. Such as 10001(linoquery.com) = 5GB ---> Company Quota kavish.karkera(a)linoquery.com = 0 ? ---> User Quota If the sum of the user quota under 10001/* exceeds the 5GB limit then the mails for that particular domain should get bounced. Please Help , if this is possible. Regards, Kavish Karkera

[Dovecot] replication chain
by Костырев Александр Алексеевич 08 Aug '12

08 Aug '12

good day! I wonder if it is possible to make a chain of replication in dovecot 2.1.9. Now I'm using two way replication(I use proxy to redirect users) and it's working just fine but is it possible to setup replication like this: serverA ---> serverB --> server C <--- I've added additional mail_replica2 on serverB and after restart dovecot didn't complain about errors, with doveconf -n I am able to see two replica's settings but user's mails aren't replicating to server C. no errors in logs. I want to use server C as backup server with lvm snapshots.

Do the same user(s) have this problem and/or do each user have their own mail configuration for their mail readers? If yes, I would also check that the port and security protocol matches (i.e. clear/TLS/SSL on ports 110/110/995 respectively). Mismatched configurations could cause what you describe. Log messages could also be helpful here. Joseph Tam <jtam.home(a)gmail.com>

Re: [Dovecot] redirect actions exceeds policy limit
by Mike Greene 07 Aug '12

07 Aug '12

Thank you David, I saw that in the share/docs but we didn't have the /conf.d/ folder or any of the extra conf files in place. I created that directory, copied the file over, made my changes and all is well again. Not sure why things were setup the way they were, after looking at the other files in conf.d it would appear the previous sysadmin had merged a lot of those bits and pieces into the main dovecot.conf file. Perhaps leftovers from v1.x days. Will likely address that down the road when we update that server. Mike Greene Rock Island Technology Solutions, Inc.
