Two options:
A) Assuming that you use the "relay" transport in master.cf
(which you should if relaying mail from outside):
/etc/postfix/master.cf:
relay unix - - n - - smtp
-o smtp_fallback_relay=[1.2.3.4]
B) In the transport map, specify a hostname that resolves to TWO
IP addresses. Make up your own DNS or /etc/hosts entry if you
need to.
