Modify sendmail.cf to use _only_ address-->account mappings found
in virtuser.  Make sure virtuser tables have _all_ email
addresses you want to work.

IIRC,

	R<@> $+			$: $1
	R<!> $+			$: $1

in SParse1 are the offending lines to comment out.  Edit with
caution if you choose to proceed.

"sendmail -bt" is your debugging and testing friend.

These last few lines are a trap for address-harvesting spambots.
Do NOT send mail to <blacklist@xxxxxxxxx>, or you are likely to
be blocked.
