IIRC uw-imapd went from keeping the mailbox locked (low/no corruption, but
clients error out a lot because they reasonably expect concurrent access)
to locking only when "necessary" (gets it wrong a lot, partly due to
concurrent delivery by MTAs, high corruption), as email volume increased
from the fairly low levels when it was first written. In either mode it's a
pretty lousy server even for single user use. BITD it was acceptable, but
email is much higher volume these days and there are much more appropriate
IMAP servers.

Yes, you can get lucky for a while. No, past performance is no guarantee
whatsoever of future results.
