I would myself have interpreted the above data as indicating that the
correct address to complain to in respect of Unsolicited Bulk Email
abuse actually originating from 126.96.36.199/16 is abuse@localhost.
However, it is possible that Niall may be experiencing the same issue in
respect of notifications from spam-rbl.com that we have repeatedly
experienced; that of almost all such notifications having been sent
entirely in error. Examples:
1. Email originating from well known, current insecure open proxies
listed at other DNSBLs, however spam-rbl.com parsing forged
"Received: from" header lines below the line where the insecure
proxy appears (and hence, from which the Unsolicited Bulk Email
actually originated); this is extremely common.
2. Reports concerning bounce undeliverable messages generated by
our own mail infrastructure, and MTAs hosted and operated by our
customers. Again, this is common.
3. Reports concerning email which, by even the strictest definition,
cannot possibly constitute Unsolicited Bulk Email abuse, which
is immediately apparent when such email is read by humans. One
example email reported by spam-rbl.com to us as apparent
Unsolicited Bulk Email abuse was a reply, from one of our
hosting provider customers to one of their customers, requesting
that said customer's customer's domain be transferred elsewhere,
and our customer providing details to their customer of how this
process should be undertaken (explanatory details re: the
Nominet IPS tag process, etc).
The majority of notifications sent to us by spam-rbl.com do not in
fact relate to abuse originating from, or involving, the easynet
network in any way. In fact, I would go so far to suggest that the
greenest newbie spam fighter, having spent a couple of hours or so
parsing a primer on how to read headers, would generate on average
a higher percentage of correctly targetted complaints.
