If you're on Linux, you might find the msmtp-gnome package useful. It allows you to store your password in the gnome-keyring. It's better than storing passwords in clear text in config files, but I don't know enough to tell if it'll satisfy folks who are serious about security. I use offlineimap for "incoming" mail, and that uses the gnome keyring too, but that is probably irrelevant to your needs. HTH, mandar.
