Mozilla supports SSL everything, including NNTP, POP3 and IMAP over SSL.
Mozilla also supports the STARTTLS and STLS extensions for in-band SSL
negotiation of IMAP and POP3, respectively. Though, I don't think popa3d
supports in-band negotiation; uw-imap does.

KMail and Evolution also support IMAP and POP3 with SSL in one or both
forms. Mutt support SSL for IMAP and POP3 (not in-band, as far as I know).
Pine might support SSL.
