[TriLUG] sendmail header question

[Turnpike Man]

If one wanted to apply this by editing sendmail.mc and using m4 to apply the
change??  And if this can't be done this way, someone want to enlighten me on
why the heck I would have to edit a drunk welch's jibberish to configure an
email server??  And... also the mystery behind people constantly telling me to
never touch the sendmail.cf file directly.

BTW, good to know as I would be running an email server internally using NAT as
well.  I suppose I could do this or to the xinetd thing with port 25.

OH, and that fix someone posted about the aol.com:smtp_server.nc.rr.com ...
that is also a direct edit to sendmail.cf wasn't it!!  ARG I hate that file
already!!

laters,
David M.
