Yow. What a nightmare. I can think of several techniques for gate
crashers. The most trivial, and the one you are probably looking for,
is to get an alias in one domain or another. There are a lot of
systems on the Internet where you can get an account fairly easily,
often for free.
Also likely is a collaborator on your list that happens to be in good
standing is sending him copies of postings.
The worst case is if he has su access to a system that handles a lot
of Internet mail, including acting as a gateway for *your* system. There
are all sorts of games a hacker can play with "catching" mail, corrupting
it, and re-sending it, making it impossible to trace. If he is doing
this, you may have a case to take to the police. This kind of hacking
is against the law and its possible the owner of the system he is using
is not even aware of it.
Good luck,
