You might want to consider using TLS/SSL for IMAP. That's more work to
set up on the server, and less work to use on the client. I use IMAP
with TLS/SSL, and a "nearby" SMTP server (the server of the
university/work/ISP, etc. depending on location) and I find it very
convenient. I use webmail over HTTPS if I have to read my mail on a
public computer, and ssh and putty on slow connections

vulnerability prone than mine.
Anyway, the choice is yours :)
