Re: [Asrg] Some data on the validity of MAIL FROM addresses

[Kee Hinckley <[e-mail]>]

Some anecdotal evidence in the "what will they do if you make them 
have a real from" category.

Domain:		netoes.com
Content:	Printer Cartridge Spam
From:		[e-mail]
Return-Path:	[e-mail]

Domain contact has fake phone number
Web page is empty (but has the title e-i1.com, also an empty page)
No PTR lookup on the IP addresses.

The Return-Path does send a 250.  In fact a little testing shows that 
*any* non-relayed address sent to smtp.netoes.com will be accepted.

They appear to have a number of different IP addresses
64.95.116.98, 63.251.54.72, 64.95.116.101...
But they all hang right off of border5.ge4-1-bbnet2.sfo.pnap.net.

So.  There he sits, "validating" every message sent.

Mind you.  I'd still like to see a better way to validate From 
addresses, and I do think it would help the spam situation.  But...

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
