"WHYNOT.NET" is a common forgery in "Received:" lines. The domain
does not exist. (The "Received:" lines above that forged one
indicate the spam's actual source.) The "Received:" lines starting
from the bottom-most one mentioning ASA's server are read top-down:
] Received: from mail-relay.ubc.ca (mail-relay.ubc.ca [184.108.40.206])

Two internal mailer hand-offs within ENGLISH.UBC.CA.
] Received: from sat1 by english.ubc.ca (Mercury 1.31);
] 13 Jul 98 20:41:43 +1100
"sat1" is neither a fully qualified domain name, nor is it an IP
address, nor does it look like an internal hand-off. ENGLISH.UBC.CA
isn't configured to tell us where it got the mail from, and that is
why the spammer used it to relay the E-mail (to hide his actual ISP
so he won't get kicked off). Every "Received:" line below this point
cannot be trusted and is almost certainly forged.
Complain to "firstname.lastname@example.org" or "email@example.com"
(ubc.ca is the University of British Columbia), and tell them to
fix their mailer so that (1) it reports IP addresses of connections
(so we could tell where the spammer was operating from), and (2) it
doesn't relay (so that the spammer couldn't have reflected the spam
off of it anyway).

Forged. Cues: "mx.whynot.net" is advertised as the inverse-lookup
of 126.96.36.199, but that domain does not exist (and that IP
address doesn't have reverse DNS). EDT is not seven hours behind
Also seen within the spam:
] <A HREF="mailto:email@example.com">
Also complain to USA.NET (firstname.lastname@example.org) and tell them to terminate
the account that the spammer is using to collect replies.
