OR, one of those SMTP on-ramp things like nullmailer. If you feel
strongly that you don't want a full fledged MTA on your machine, you
can use an on-ramp to replace /usr/sbin/sendmail and the send
executable. If you're using an on-ramp, I recommend nullmailer because
it employs a queue, whereas some of its competitors just block until
messages are sent.

Here's some stuff I wrote on nullmailer:
