Hi,
Some time ago I posted the below but never got a reponse that I could work with.
So i am retrying now in the hope that there might be a better idea/suggestion on
how to approach this.
Situation;
I have two nodes, which should replicate to eachother. My main machine receives
most mail and the other one receives mostly system messages and should get
replicated. (This used to be delivered on both machines, but given the issues
below I had to make sure that the customer email at least arrives on machine A,
as detailed below).
When a mail arrives on main machine (A) everything is fine and things are
synchronised asap. Customers can see the email directly via webmail/imap.
When a mail arrives on the secondary machine (B) the replication is not issued
until machine A starts a sync session. Customers do not see the email on machine
A via webmail/imap.
When a mail arrives on A, the synchronisation occurs, and all messages on B, not
yet on A, are synchronised as well. Customers can now see the email on machine A
as well via webmail/imap. Sadly this can mean that emails that became visible
are hours late (read: were delivered hours before, but not visible for the
customer).
Both machines are configured through puppet, only individual settings like IP
addresses and certificates are different because well, they have to. I included
the difference below, and both ?doveconf -n?s. If someone has a suggestion on
seeing why machine B is not issueing (or does not seem to issue) replication,
let me know. I verified that I can connect to the remote machines via IPv4 and
IPv6 (for doveadm / replication purposes).
Difference between configurations;
