IIRC, there is a federal law making it illegal to use a computer system if
you are not authorized to use it. It was designed back in the days where
hackers would dial random numbers to find computers to dial into. A message
like "Only employees of Acme Systems are authorized to use this computer
system" would make it illegal for a non-employee to access it.
If the law is still around, I'm certain that a message in the SMTP headers
would do the trick. Although normally a spammer could claim that he didn't
see the headers, if they are targeting multiple SMTP relays simultaneously
to defeat their anti-spam tactics, it is clear that the spammer is aware
that they are doing something unwanted, and a court would likely say that
they knew enough to find out that they were not authorized to use the SMTP
relay.
An example is HotMail's headers:
220-HotMail (NO UCE) ESMTP server ready at Wed Mar 15 08:36:31 2000
220 ESMTP spoken here
The "NO UCE" is almost certainly an attempt to notify potential spammers
that unsolicited commercial E-mail is not authorized, and/or they may do
filtering.
