GNUPG, or "GNU Privacy Guard", is an open source replacement for PGP (see overview of PGP, and using GNUPG).
mutt is a mail program, a descendant of elm. It is more modern
than elm, and is being actively developed. It also has a reputation
for being less buggy and more secure than pine and elm, but just as
easy to use. Current elm users should have no problem switching to it.
Note that one of the reasons many people dislike our e-mail software is that programs such as mutt or elm use the vi editor by default, and that can be hard on the novices. But most mail programs can be configured to use any text editor!
tkrat is a GUI mail client, somewhat similar to Eudora and Outlook. It handles attachments well and is very customizable.
