Here's an alternative:
Instead of going through all this effort, skip the SMTP security server of FW-1, put
qmail (www.qmail.org) on a Linux box in your DMZ and use tcprules to limit the
networks that are allowed to relay to your own.

Regarding mail anti-relay, FW-1 v4.0 SMTP security server takes into
account source routing (WI-124 Sept 1998). My feeling is that they refer
to an old practice, mentioned page-32 (6.2.7) of famous RFC822. This is
not enough at all to stop spammers using your mail server as a relay.
