  Stunnel or the like does protect your pop3/imap (and sasl?) password 
though (depending on AUTH type you're using), and the client-server
connections are much easier to eavesdrop on (eg. on a wireless or cable
network) than are server-server connections (on internet backbone links,
etc.).  So when doing the fore-mentioned evaluation, definitely don't
deduce that it's next to pointless to have encrypted client connections.
