Just don't open the same mailbox with Dovecot and UW-IMAP at the same
time! You may also find that UW-IMAP changes the UIDVALIDITY sometimes,
which will cause Dovecot to complain next time it opens the mailbox, but
Dovecot will be happy again on subsequent opens.

We did this for a couple of months before we migrated to Dovecot.

Best Wishes,
Chris
