[Scspamcop] Re: Open redirectors, Microsoft ESMTP services and relaying

[Tester]

After 6 days, I got bounces on the me%mydomain at relayserver and
"me at mydomain" in quote marks relay tests I attempted on
mail.go2abs.com [67.124.176.170]) manually using a return-path which I
own.

There was no explanation as to why delivery failed - just

Reporting-MTA: dns;corp.go2abs.com
Received-From-MTA: dns;world
Arrival-Date: Thu, 26 Apr 2007 14:08:58 -0700

Final-Recipient: rfc822;"jmrubin at nerdshack.com"@go2abs.com
Action: failed
Status: 5.1.1

(I gave the SMTP command "helo world" which, of course, is a pun on
the first example in the first "C" programing book.)
