One-way sync will work fine. Two-way sync might be a bit troublesome. For redesigned dsync I've started thinking about kind of a 1,5-way sync. :) That would make sure that all messages from A are copied to B and no messages are deleted from B, but doesn't try to copy new messages from B to A. http://wiki2.dovecot.org/Migration/Dsync anyway has some docs.
