Dovecot replication causing deleted emails to reappear

[Asai]

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?
