SUMMARY = "Postfix Mail Transport Agent"
DESCRIPTION = "Postfix is Wietse Venema's mail server that started life at \
IBM research as an alternative to the widely-used Sendmail program. \
Postfix attempts to be fast, easy to administer, and secure. The outsidei \
has a definite Sendmail-ish flavor, but the inside is completely different."
