[Esd-l] Totally Stumped - Sanitizer on an inbound relay

OK, now I'm still stumped but check this out. As I stated earlier, this host
is a relay, so there should be no local deliveries. I went with the rules
below but changed $=w to $=R to read the relay-domains file instead. Now
check out the results of sendmail -bt.  NOTE: bob.com is NOT in my relay
domains file. Really, I don't see why the rule isn't being invoked, unless
it is in the wrong location in the cf file? It's at the tail end of RuleSet
98.

Please keep the advice coming!

My LOCAL_RULE_0 is


R$*<@$=w>$*     $#procmail $@/etc/procmail.d/gateway-filter.procmail
$:$1<@$2.pr
ocmail.>$3
R$*<@$=w.>$*    $#procmail $@/etc/procmail.d/gateway-filter.procmail
$:$1<@$2.pr
ocmail.>$3
R$*<@$*.procmail.>$*    $1<@$2.>$3

Which is quire different - notice the $3 at the end of the lines.

It looks like it isn't rewriting the addresses correctly!
