Sendmail is an alternative Mail Transport Agent (MTA) for
Debian. It is suitable for handling sophisticated mail
configurations, although this means that its configuration
can also be complex.

Don't try anything fancy in sendmail without using this for guidance.

op.{ps,txt}.gz -- The care and feeding of Sendmail.
