Dear list,
I have setup a master-master replication setup. My primairy MX's send
email
over on a DNS loadbalanced way, so DNS is doing some kind of
round-robin
way of sending mail to both master servers.
I found out, that on one of the two machines, the email
synchronisation
is
heavily delayed. Lets assume server A receives a mail from the MX; it
synchronises almost instantly with the other server.
Whenever server B receives the email, it could take up to several
hours
to
synchronise the email, it seems that it is not detected prior.
I have been dealing with this for months.

For a band aid I use this crontab entry. On the 2nd mail server.
*/15 * * * * root /usr/bin/doveadm sync -u "*" remote:mail1

Are you guys using LMTP to deliver from your MX server to the mailbox
server?
Local delivery on the destination server is LMTP but the transport
between
MX and destination server is just plain SMTP.
I could try and revert to dovecot-lda and see what that does?
I don't think that'll help. From what I understand, LMTP is required for
replication on delivery.
Out of curiousity, why do you use SMTP from the MX to the destination
server instead of LMTP?
