Not to mention how would you prove they are spoofing their domain?
Here's where for the past 2 years (until a few days ago) my mail was
hosted by me. Never in two years did I have a whisper of a complaint filed
against me for spam or any other kind of abuse. I did it with the full
knowledge and consent of my provider. In fact, I'm pretty miffed I can't keep
them through a 2nd move.
{grey@dmiyu:~} host teleute.dmiyu.org
teleute.dmiyu.org A 66.51.217.42
{grey@dmiyu:~} host 66.51.217.42
Name: adsl-66.51.217.42.dslextreme.com
Address: 66.51.217.42
One would think that would be rejected since I've "spoofed" my domain and
clearly am not sending mail for dslextreme.com. In truth I just didn't want
to bother them with a request for a reverse record.
On a tangent in those 2 years only one message was ever refused because my
forward and reverse DNS didn't match. Ironically enough it was a complaint to
abuse@??? about one of their customers spamming. :/ I'd hate to see for
the practice to rise even though it would no longer affect me.
