Thanks for the reply and explanation.  The user had sent a message to the address, and it was automatically added to the user's friends list.  The the user added a filter to reject messages from that address, but it didn't work.  I then tried to globally block the domain, but that didn't work, either.  Now I know why.  :-)

I removed the address from the user's friends list and disabled automatically adding outgoing addresses.
