	are you using m4 to create your .cf files?
	S98 is the result of LOCAL_RULE_0.
	why not use the virtusertable feature?
	ti will reroute mail for user@host to someone@somewhere.
	the mapping is repeated till no additional changes result.
	beware loops!  sendmail s trying after 50 mappings.
	this rewrites the user,host part of the user,host,mailer
	triple only.  

	lookup key is "user@host"
	if that fails
		lookup key is "host"
	if that fails too
		no write takes place.
