Hi Knute,

here are my dovecot config's. It seems to be somehow sometimes for me. I
am not expert of dovecot just started few weeks ago. I have been playing
around and I am not sure what makes mine to work.

I have 2 similar configured servers. Config's are not identical. I had
problem with notification "Error:
open(/var/run/dovecot/replication-notify-fifo) failed: Permission
denied." Still not working perfectly. Replication worked when I used
that users UID in "service aggregator" and "unix_listener
replication-notify." Then the other user was failing ....

I am using only imap part and haven't test other protocols if they work
or not. The other protocols like pop and sieve came by default. I didn't
bother to remove them.

#doveadm sync -A remote:u15dove2 command will sync things but I still
have some problems. Hopefully this might get you to correct track.

One more thing. I copied root's ssh keys as authorized_keys so I can ssh
-lroot other machine without password and visa verse.

So sorry no perfect solution yet avail ....
