FREE !!

If it's free then it will eventually go away.  I've used their free
reporting services and they are great.  Why not pay the meager $12/year and
give them some support?

Isn't this what caused the demise (partly) to the HPe3000?  No money, no
product, no support.

Of course we could regurgitate what's already been said so think before
responding.

Subject: Re: [HP3000-L] OT - new SPAM technique...how's it done?


X-no-Archive:yes
Since Bruce has given a detailed explanation of how this can be done, you
(John Lee) might consider, and might even enjoy, reporting that spam thru
www.spamcop.net using their free reporting service. Be sure to check the
Technical detail reporting check box when you report, and the resulting page
will show you an analysis of the SMTP header.

I've been able to use this information to write some spam filtering rules.
And I keep wondering just how hard it would be for major ISPs to perform
more of this validation. For instance, almost all of the spam I receive at
work first passes thru someone's open relay, with most of these abused
relays being in China, Korea, Japan, and perhaps a few other Asian
countries. So, filtering on those country codes in the headers catches
those. Were it up to me, I would filter those at the server. But I cannot
even get AT&T Broadband, my home ISP, to agree to respond to any spam that
does not originate on their own network. Imagine that. NONE of the spam I
get at home originates on their network. Imagine that.
