I use a slightly modified msmtpq for queuing and I have some hooks that
run profiles to choose SMTP server and other options based on
sender/receiver/last search.  Passwords are plain text but my fs is
encrypted.  If you want, you could encrypt the password file with gpg
and use gpg-agent to grab the password as needed from the file.

Good luck.
