Finally, there's the MUA (Mail User Agent), which is essentially
end users use to view the mail. There's tons of those, but most common
I've found on Linux are Thunderbird, claws-mail, mutt, Balsa, KDEMail,
etc. Note that it is the MUA that uses protocols such as IMAP4, POP3,
MAPI and the like.
Allow me to mention Evolution, which AFAIK is the default MUA for
Gnome. I don't use Gnome but I have used Evo for many years. It's also
one of the few free MUAs that can talk directly to Exchange (i.e. not
via Outlook Web Access), which I don't use but many people do.
