Like many documents, it's both good and bad.  The author gives an excellent
(and complete) description of setuid/gid, permissions, and flags ... but then
he goes on to arbitrarily announce that you should increase both send and
receive TCP buffers to 64k, with no explanation.  Jacking these values up
is not always a good idea, and I doubt if it's a good idea with a mail
server.
