It depends on your definition of "outgoing".

If you can define it as mail sent from your own IP addresses, maybe
you can define it by testing $RelayAddr.

Testing by the sender address (which is $Sender not $sender) is
not as good, since anyone might send mail with your domain in the
sender address, including spammers and viruses.

Something like this:

if ($RelayAddr =~ /66\.8\.25\./) {
	# add that attachment
}
