Replacing the local mailer is conceptually simpler than what you're doing.

The user specification is incorrect on the second rule: you're missing
the brackets, the period before "procmail", and $3 (without $3 all route
addresses would be completely hosed).  I would also suggest being more
explicit in what you're expecting to match with the first rule:

S99
R$*<@$+.procmail>$*	$@ $1<@$2>$3	# procmail has already looked at this.
R$*<@$+>$*		$#procmail $@/etc/mail/procmail.rc $:$1<@$2.procmail>$3

That should make it more clear what is going on.

When you save the message to /var/log/SPAM you're losing the envelope
address info.  You should save it in a header:

	SENDER = $1
	RECIPT = $2
	:0:
	* ^Subject: Make Money Fast
	|formail -I"X-Envelope-Addressing: $SENDER $RECIPT" >>/var/log/SPAM


and no, you can't just place $* or $@ in the quotes, because the above
will be executed by the shell.  $@ wouldn't be correct anyway (it would
create more arugments for formail) and procmail doesn't expand $*.
