        I had a situation several months ago where a member of the list
started spamming one of my lists because he was having problems
unsubscribing.  After contacting his ISP, I initially had problems with
them because they flatly denied that the mail was originating from
their host.  I introduced a minor modification into the SMTP server
which logged the IP address as well as the host name.  This provided
the evidence that the mail was indeed originating from their host, and
they took the appropriate action.
