First off I don't think this is a postfix problem. I'm hoping someone here
has seen something similar and can help me out. Google so far has turned up
nothing for me. :(

I get this same warning from gmail, yahoo & live. The email goes straight
the the junk email folder on all of these systems. :( Makes me very unhappy.

Log snippet: (74.86.26.64 spellwellinc.com is my server)

I assume the warning: 27.86.26.64: address not listed message if from the
far end. I check DNS and see PTR is there. Then check dig -x

kenhat: dig -x 74.86.26.64

So dig finds the correct lookup. I'm stumped on where to go now.

I must have something screwed up in DNS but can't find it. I can post my
zone file if that helps. Anyone out there that can toss me a bone?

I'm only using postfix for outgoing mail. No incoming.

Just in case someone thinks my postconf might help.
