Hello,
I'm using dovecot 2.3.10 in OpenSUSE and I have configured a master/master replication between two backends, it works well but I have found an issue with the replication of the HIGHESTMODSEQ. When I move a set of message from a mailbox to other, e.g. move 3 messages from INBOX to Junk, the HIGHESTMODSEQ get different on each server, with no errors in the log:
[Borrador] 34:34 [Sent] 63:63 [Drafts] 12:12 [Trash] 146:146 [Junk] 219:218 [INBOX] 1133:1130
It can be fixed executing a full sync: $ sudo doveadm -D -v sync -u user@test.priv -d -l 30 -U
But it is not a solution because it happens all the time that a user move messages.
I'm using ActiveSync and the ActiveSync server use the HIGHESTMODSEQ as part of the synchronization key (sync_key), so in that situation the server detect changes on the mailbox if it connects to the backend with a different HIGHESTMODSEQ that it previously cached, causing a loop beetween the ActiveSync server and the the email client, where the server constantly inform email client about nonexistent changes.
Could it be a bug in Dovecot replication? How can I solve it?
