Hi Norm,

Do you have trouble following the Received headers, bottom to top?  :-)

    Received: from jad.dad.org (unknown [])
        by mailwash26.pair.com (Postfix) with ESMTP id 8626B1B311
        for <address@hidden>; Fri, 25 May 2012 07:55:23 -0400 (EDT)
    Received: from jad.dad.org (localhost [IPv6:::1])
        by jad.dad.org (Postfix) with ESMTP id 83FA0123457;
        Fri, 25 May 2012 04:55:22 -0700 (PDT)
    Message-Id: <address@hidden>

You passed it to Postfix on your localhost.  Postfix then passed it to
mailwash26.pair.com in order to reach me.  pair added the top `received'
header and said it was speaking to but couldn't resolve
that to a PTR record, therefore `unknown'.

Sure enough,

    $ host
    Host not found: 3(NXDOMAIN)

That's from a block owned by Raw Bandwidth Communications.


Not many of them have reverse PTRs.

You need to ask your contacts "there" how to always have a PTR for your
IP address, currently  It's not a good idea to run a
mail server from a machine without one these days which is why, once
again, I'd have thought you should be using your ISPs smarthost to send
mail to others on your behalf.

Cheers, Ralph.
