SPF Blocks SPAM, not sun's rays

Sat, 03 Apr 2004 12:00:00 GMT

A new technique known as Sender Policy Framework (SPF for short) may be the tool to get rid of those bounces that appear to come from you but really come from either a virus or a SPAM twerp that has your address. SPF works by having a domain publish (in their public DNS) a list of valid mail servers from which mail from that domain could be sent. SPF-conforming MTAs will shut down mail that couldn't have really come from the given domain. Find out more about SPF.

It seems that even SPAM PERPs - the ultimate parasites of the networked world - follow Gilmore's Dictum, "The Net treats censorship as damage and routes around it." In fact, on the same site, you'll find John Gilmore's grokmail, which he views as a better alternative than all of the anti-spam measures to date (note: grokmail is not released yet).

SPAM perps flog anti-SPAM tools

The funniest thing I've seen in a long time is SPAM from obvious SPAM perps, offering to save me from the menace of SPAM! As if I hadn't already told everybody who'll listen to never buy anything from a SPAM perp, not even once, the very notion of trusting software from an unknown software house to guard against this malignancy just had me rolling on the floor laughing. Of course the laughter stopped after the tenth or fifteenth copy I got...
This won't help MS-Windows users, but if you run a UNIX host with the ubiquitous Sendmail, or your ISP does, you or they should check out this nice simple mail filter milter-regex.
