When that error happens, it recreates the message UIDs. Those UIDs are
also used in POP3's UIDs, so if they change that could explain why the
messages are downloaded again (for users who use "leave mail on server"
option).

What Dovecot version do you use? 1.0-7 doesn't exist, maybe 1.0-test78?

Do you use NFS? Are there other software modifying mboxes than Dovecot
and Postfix?
