Pine and UW imapd both support STARTTLS for all relevant protocols
(SMTP/IMAP/POP/LDAP client for Pine, IMAP/POP server for imapd).  They
also support Kerberos authentication and datastream encryption for all
these protocols.

Evolution does?  I tried out the Evolution 1.0.3 that comes with my RedHat
7.3 distribution, and it appeared not to support STARTTLS for IMAP or
SMTP.  When I told it to "use secure connection (SSL)" for SMTP it tried
to connect to port 465 (the deprecated smtps port) and failed.
