synchronous replication based on priority
by Sylvain Allemand 18 May '16

18 May '16

Hi, i see in this page (http://blog.dovecot.org/2012/02/dovecot-clustering-with-dsync-based.html) : "Optionally the replication plugin can also support synchronous replication of new mail deliveries. In this way it connects to replication-notify UNIX socket, tells it to replicate the user with sync (=highest) priority and waits until it is done or replication_sync_timeout occurs. The IMAP/LMTP client won't see an "OK" reply until the mail is replicated (or the replication has failed). The synchronous replication probably adds a noticeable delay, so it might not be acceptable for IMAP, but might be for LMTP." is this fonctionnality effective for LMTP ? If so, where is the config ? The wiki says that replication is asynchronous.

doveconf filter broken?
by Tom 18 May '16

18 May '16

I'm running dovecot 2.0.9 According to the man page, the command: # doveconf -f service=imap is supposed to show just the settings for imap. Is this correct? When I issue the command it shows everything. Why?

Reloading dovecot and postfix after updates
by ＠lbutlr 17 May '16

17 May '16

Recently someone used webmin to update dovecot, which went fine. However, after the update no one could login to the mail server because of the mismatch in the versions between what was installed and what postfix was expecting. Other that bapping the person on the head and saying “don’t do that” is there anyway to force a reload of postfix after dovecot reloads? Like adding a postfix reload to the dovecot rc.d script or someway of linking them so that if either version changes they both get reloaded? (I don’t even use webmin myself, so maybe it’s even possible through it?) I mean, it’s unlikely to happen again at this point, but still… -- "...and Digby considered how much he liked salt..."

Errors on Cross-Protocol Locking nbmand (ZFS Solaris)
by Andrew Watkins 17 May '16

17 May '16

Hello, I get the following errors when I move large e-mails (i.e. about 15MB) into mail files. May 17 13:26:48 mailer3 dovecot: [ID 583609 mail.error] imap(andrew): Error: fdatasync() failed with mbox file /home/andrew/Mail/nbmandON/mbox: Permission denied May 17 13:26:48 mailer3 dovecot: [ID 583609 mail.error] imap(andrew): Error: ftruncate() failed with mbox file /home/andrew/Mail/nbmandON/mbox: Permission denied May 17 13:26:48 mailer3 dovecot: [ID 583609 mail.error] imap(andrew): Error: close() failed with mbox file /home/andrew/Mail/nbmandON/mbox: Permission denied Background I am using Solaris 11 ZFS & SMB for my users home files with Solaris SMB protocol mandatory locking (nbmand=on) If I turn nbmand=off then I do not get any errors, so it is to do with SMB locking. I know this may not be a dovecot error, but any pointers why it is doing this so that I can report it to Oracle. I tried creating a small C program to mimic the same problem but no luck, since I know it would make it easier to get Oracle to fix it. # /usr/local/dovecot/sbin/dovecot --version 2.2.24 (a82c823) Thanks for now, Andrew -- Andrew Watkins * Birkbeck, University of London * Computer Science * * http://notallmicrosoft.blogspot.com * * UKOUG Systems SIG Chair * * UKOUG Tech committee * * tel: 020 7631 6720 *

Dovecot configuration: Home dir not found
by Divakar BM 17 May '16

17 May '16

Hi, I've my mail solution configured on Server-A with webmail, Dovecot and Postfix. I'm trying to deploy only Dovecot and postfix on Server-B to reduce IMAP/POP3/SMTP load on server-A. Please note server-B does not mailboxes. It should be mapped to mailboxes on server-A. While the LDAP query from Server-B to Server-A is going successfully, the imap service on Server-B is throwing the below error. imap(user(a)example.com): Debug: Home dir not found: /mail/vmail/**/ I guess imap is looking for *home dir* in server-B. How do I tel the imap that home dir is on server-A and not server-B. Please let me know if there exists a configuration parameter for the above.. Thanks Divakar

Sieve extension for testing for mailbox
by Jon Kristensen 16 May '16

16 May '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi! Which Pigeonhole Sieve extension should I use to process/test a message depending on whether the message is in a particular mailbox? (Is it the mboxmetadata extension by any chance? If so, I would appreciate if someone could tell me what the reason is for it not being enabled by default.) The reason I want to perform this test is that I have configured my MTA to deliver "outgoing" e-mails to my "Sent" IMAP folder, and these messages arrive unread. I would like to mark them as read using Sieve.

Hi, I've tried to upgrade to dovecot 2.2.24. It seems that lucene reindex issue should be fixed. But instead of this dovecot indexer-worker crashes very often for me. I'm attaching backtrace. Please let me know if you need backtrace from binary without optimizations. -- WBR, Dmitry

SSL on doveadm port
by Patrick Domack 15 May '16

15 May '16

I have been attempting to setup ssl on the doveadm port. So far this works fine, as long as the global certificate is used. I wanted to use a different certificate, one that machines the machine name, instead of the generic mail certificate, but I have not been able to figure out how to do this. Attempts to add the certificate in the services section with the ssl = yes option, cause syntax error, and dovecot doesn't start. Creating a protocol doveadm section with it, is ignored, and setting up a local section with it in it, is ignored also.
