I think that statement should be qualified with "...if you're an ISP or have
an complex multi-domain site."
Otherwise, it's trivial in the case of sendmail. It took me maybe 10 minutes.
(Copy a ruleset from either the sendmail.org or spam.abuse.net Web page
into sendmail.cf, add a couple of domains to a config file, kill and restart
the daemon. Done. And test... another couple of minutes.)
I really can't think of anything that would be simpler except a hypothetical
mailer that one configured by screen forms, and "permit relaying" was a yes/no
check box.
