Re: Possible bug in handling IPv6 mapped IPv4

Here is another area

Received: from unknown ([::ffff:x.x.x.x] helo=[]) by

Where x.x.x.x is a valid public IPv4 address with reverse PTR. But ASSP is
failing to strip out the IPv4 portion and do a lookup on that. Thus it shows
unknown rather than the PTR for the IPv4.

Example  (not my ip got this via google  "comcast ffff")

Do a host lookup on the IPv4 portion you get a PTR. But ASSP is not capable of
such when ::ffff: is present.
