Hello,

this sounds like the replication problem that occured after 2.2.33.2:

As far as I remember there is no fix yet.

Best regards Gerald

Hello,

Thanks for the info and workaround!

I found and have the same problems after read your mail :-(.

Hello!

I noticed these in the logs since upgrading from 2.3.6. to 2.3.7:

Jul 13 11:52:10 turin dovecot: doveadm: Error: dsync-remote(reio@mrstuudio.ee): Error: Exporting mailbox INBOX failed: Mailbox attribute vendor/vendor.dovecot/pvt/server/sieve/files/MR lookup failed: Mailbox attributes not enabled Jul 13 11:52:11 turin dovecot: doveadm: Error: dsync-remote(reio@mrstuudio.ee): Error: Exporting mailbox INBOX failed: Mailbox attribute vendor/vendor.dovecot/pvt/server/sieve/files/MR lookup failed: Mailbox attributes not enabled

After turning on mailbox attributes these errors went away:

mail_attribute_dict = file:~/Maildir/dovecot-attributes

protocol imap { imap_metadata = yes }

But now the errors are replaced with (when deleting mail):

Jul 13 12:04:32 turin dovecot: imap(reio@mrstuudio.ee): Warning: /home/vmail/mrstuudio.ee/reio/Maildir/dovecot-uidlist: Duplicate file entry at line 2: 1563008644.M18534P25946.orc.mrstuudio.ee,S=4180,W=4262 (uid 23030 -> 23031) - retrying by re-reading from beginning Jul 13 12:04:32 turin dovecot: imap(reio@mrstuudio.ee): Warning: Maildir /home/vmail/mrstuudio.ee/reio/Maildir: Expunged message reappeared, giving a new UID (old uid=23030, file=1563008644.M18534P25946.orc.mrstuudio.ee,S=4180,W=4262:2,S)

The mail message reappears on the other side of dsync and eventually I end up with 3 identical messages in trash after I've deleted them on both sides.

Thanks for any advice, Reio

Same here (in my case: on OpenBSD -current, mdbox, pigeonhole 0.5.7). I have backed out to 2.3.6 + pigeonhole 0.5.6 and it's happy again.

Instead of downgrading, you could've attempted

mail_attribute_dict = file:%h/dovecot-attributes

to enable mailbox attributes. This should fix sieve script replication too.

Perhaps, but when dealing with mailboxes out of sync between the two replicated machines the first thought is to backout the change that triggered the problem, rather than guess things that might help, especially when they aren't mentioned in the release notes (actually the only thing I find in either NEWS or ChangeLog relating to attributes/metadata at all since the last release is adding methods to access this via lua API?).

So after adding "mail_attribute_dict = file:%h/dovecot-attributes" (alone, I have not configured to use the METADATA extension and the file is not being created) and going back to 2.3.7, syncs are now working and I see no more "lookup failed: Mailbox attributes not enabled".

Prior to adding mail_attribute_dict, with a two server dsync setup, new mail was syncing from A->B ok but new mail arriving on B didn't sync to A.

I'm happy that things are now functioning ok on this setup but given the limited information about what's happening and no information about config changes needed for 2.3.6->2.3.7 I'm a bit twitchy about 2.3.7 in OS packages (I reverted it to 2.3.6 in OpenBSD after running into the problem) so it would be nice to know a little more about what's going on here.
