dovecot - Nov 2014 - Dovecot replication causing deleted emails to reappear

Greetings,

I've set up replication successfully on two Dovecot servers.  I had fully
synced the servers but then took one offline for 2 weeks.  When I restored it,
the servers synced but ended up replacing deleted emails in random people's
inboxes.

I'm using maildir.

Does anyone have any insights as to correcting this issue?

Asai
