FWIW, I'd suggest using UW IMAP over dovecot.
I tried moving to dovecot, given that UW IMAP is no longer supported
or supplied with Fedora (which my mail server runs), but:
- it doesn't support as much in the way of secure login mechanisms,
in particular it doesn't support GSS-API (which I like to use)
(I can't remember if it supports SASL, but if it doesn't then the
only secure mechs Dovecot supports is plain-over-TLS or TLS certs,
one of which I find problematic, as clients sometimes silently
fall back to non-TLS if TLS fails - boom there goes your
password, and the latter is completely icky and unacceptable to me)
- Dovecot doesn't support as many IMAP search criteria (iirc), makes
searching through mail noticeably slower (iirc)
- Dovecot is noticeably, nay *infuriatingly*, slow compared to
UW-IMAP, particularly on large mailboxes.
(this is despite dovecot maintaining reusable indices on-disk, yet
still manages to be slower than UW-IMAP, which does not keep them
The latter was the tipping point and made me go back to UW-IMAP,
*despite* the extra bother of having to track UW-IMAP releases myself
and make FC RPMs, over dovecot which is maintained in FC.

What makes the universe so hard to comprehend is that there's nothing
to compare it with.
