   Demon show the full details of their receiving gateway, and immediately
below that is the authenticated sending IP address, together with any
details, forged or valid, as supplied by the sender. A whois search on the
true IP address supplies the sender's ISP details, which usually include an
abuse at address, and I include the true IP address and date received in the
subject line when I forward the entire junk mail complete with header and
all attatchments to the ISP.
   The amount of junk received has been reduced by Demon starting to use
Brightmail filtering, it reduced even more when I started forwarding junk to
ISPs, and I have not received any since I mentioned what I was doing on this
newsgroup. Perhaps our mail is being read by one of the senders.
