Hi
I noted that postfix is writing headers with "unknown" instead of the IPv6
reverse DNS that I know exists.
e.g.
Received: from merboo.mamista.net (unknown [IPv6:2001:470:1f0b:1055::1])
by tigger.mamista.net (Postfix) with ESMTP id 581F21100B4
for <[email protected]>; Mon, 22 Mar 2010 02:18:00 +1100 (EST)
$ dig -x 2001:470:1f0b:1055::1 +short
merboo.mamista.net.
I'm still convinced the problem is not with postfix but is there a way to
imitate it's IPv6 reverse DNS lookups so I can get closer to the cause of
the problem?
cheers
Marty
