[Cialug] New SPAM source!

[L. V. Lammert]

Has anyone noticed the new SPAM process - create a trivial domain name
(e.g. enclavetcc.com, firgrovemotel.com, chaddsfordchiropractor,
beautyswapper, and many others), setup valid reverse DNS, and, Viola' - a
way to send SPAM and get through to a lot of recipients!

Don't really understand the goal, however, as the test of the email does
not *appear* malicioius, and the SA score is normal. Often the embedded
links appear to be valid (e.g. cancer.gov)!

Any thoughts on identifying and blocking?
