It is the appropriate list.
I have an email server based on Matt Simerson's mail toaster
(http://www.tnpi.biz/internet/mail/toaster/) that I've managed to
get IPv6 compliant.
However, I'm having a very hard time determining exactly where the
DNS checks are performed, and how to correct an issue.
In my SA stats, the majority (+90%) of email inbound is classified
as rdns_none.
I have a suspicion that this is due to the IPv6-IPv4 mapped address
being written into the headers when I am speaking to a non-native IPv6 MTA:
Received: from unknown (HELO mail.apache.org)
(::ffff:140.211.11.2) by pearl.ibctech.ca with SMTP; 28 May 2008
09:13:00 -0000
Can someone inform me if this is an SA thing, and if so, where to
begin looking/testing with the source to correct this issue?
According to your header, there is no reverse DNS for that mail server.
If it is within a part of SpamAssassin, I will gladly submit any
patches that identify/rectify my problem.
The Received headers are parsed in Received.pm.
