Ta-Dah! It worked ... finally. I had to add
FEATURE(masquerade_header)
MASQUERADE_AS(mail.sunink.com)
in the sendmail.mc source thingy and run m4 on it, move the
output to sendmail.cf in /etc/mail/, restart sendmail and Voila!
I love Linux.
Now I just have to find out what's blasting every terminal with
mail receipt notifications in a *very* annoying manner, and I'll be
a happy little vegemite!
Cheers.
Jonathan Kelly.
