Replication failing - IMAP_SYNC_CHECKSUM Checksum Failure

[Bron Gondwana]

Sounds like you have been fiddling mailboxes.db entries and/or didn't clean it up properly?

I would recommend sync_reset on the user on the replica for a better cleanup than delete.

Oh yeah, don't create the mailbox on the replica before replicating it in, that's crazy talk - you'll get a new user with a different uniqueid.  You shouldn't be creating users on replicas.
