James Craig Burley claims copyright on the qmail-isoc patch. For
more details, see COPYRIGHT.

Apart from James' copyrights, no other copyright is claimed by the
distributors of netqmail for changes from qmail 1.03 to netqmail 1.05.
Daniel J. Bernstein has abandoned copyright for qmail 1.03.
D. J. Bernstein did not participate in, nor has he been asked to
approve of this distribution.

With this distribution, we thank Daniel Bernstein for his dedication
of qmail to the public domain.  We have taken advantage of this event
to remove the need to apply a patch.  We will distribute a Netqmail 1.07
shortly which includes enhancements.

Netqmail 1.06 is produced by this motley krewe:

qmail is a secure, reliable, efficient, simple message transfer agent.
It is meant as a replacement for the entire sendmail-binmail system on
typical Internet-connected UNIX hosts. See BLURB, BLURB2, BLURB3, and
BLURB4 for more detailed advertisements.

INSTALL says how to set up and test qmail. If you're upgrading from a
previous version, read UPGRADE instead.

See PIC.* for some ``end-to-end'' pictures of mail flowing through the
qmail system.

See http://pobox.com/~djb/qmail.html for other qmail-related software
and a pointer to the qmail mailing list.

Other documentation: http://pobox.com/~djb/proto.html shows solutions to
several Internet mail problems; many of these solutions are implemented
in qmail. CHANGES and THANKS show how qmail has changed since it was
first released. SECURITY, INTERNALS, THOUGHTS, and TODO record many of
the qmail design decisions.

The rest of this file is a list of systypes where various versions of
qmail have been reported to work. 0.96 was the final gamma version; 1.00
had exactly the same code as 0.96. To see your systype, make systype;
cat systype.
