Hi
is there any error in the log?
Can you show some evidence or an example? ie some email delivery in the master but not on the slave?
Can you be sure to check both new and cur subdirectories on master and slave?

There's precisely nothing in the log. The new mail arrives on the master, and it is as though dovecot completely ignores it for the purposes of replication.
However, I think I have solved the problem by enabling LMTP and forcing postfix to go through that rather than writing to the maildir directly. Perhaps LMTP is required for replication and I just didn't realize it. End result is (I think) it is working properly.

Sorry for empty mail, butterfingers...
Anyways, since replication is triggered by "replication" plugin, you need to involve either dovecot-lda or lmtp to the delivery process. Dovecot *will not* pick up replication need if you just drop files into the maildir as nothing will trigger dovecot code.

Thanks for confirming. Seems to be working OK using LMTP now.
