Mon Oct 22 14:33:56 UTC 2001

A query to help educate me. Feel free to flame away;
the week is young.

Every site should accept/respond to "postmaster" -- T/F?

Or is it "Every site running mail"....
Or every box running mail?

IOW: Which of the following are required vice recommended vice
best practives, etc.

a)	postmaster at example.com
b)	postmaster at mail.example.com
c)	postmaster at wizzbang.example.com
d)	postmaster at pop.example.com
e)	postmaster at cisco.example.com

and most important to me: where to I go to justify the
decisions on same?
