so, hmm the way i understand that is, if i don't specify relayhost on the
backup, and the primary MX is down..the backup MX gets an email, and it
will try and forward it directly to it's destination..so it will lookup
the MX for zaphaz.com, find the primary, see that it's down for sending
(else we the backup wouldn't have got the email in the first place),
and loop right back to the backup MX..wouldn't that then cause a infinite
loop?
