# Default-Stop: 1
# Short-Description: powerful, efficient, and scalable Mail Transport Agent
# Description: 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. Fortunately, simple
# thing can be done easily, and complex thing are possible,
# even if not easily understood ;) Sendmail is the *ONLY*
# MTA with a Turing complete language to control *ALL*
# aspects of delivery!
