“E-mail is the most widely used means of communication on the
net. Convenient? yes — safe? no. Encryption is what you need to
keep your communications private. This article shows you how you
can use the mail client Mutt and the open source replacement of
PGP, GnuPG, to secure your e-mail.”
“Most of you would have heard of mutt. Mutt is an MUA, a Mail
User Agent, which is the program that you would use to send and
receive mail. So, why use mutt when there are so many other mail
programs available? A bunch of free and not so free mail readers
exist, and each one has its pros and cons. However, apart from pgp
which has add-ons for pgp/gpg support, almost no other client
supports gpg natively. I could be wrong though.”
