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

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 198.144.207.170 but couldn't resolve
that to a PTR record, therefore `unknown'.
Sure enough,
$ host 198.144.207.170
Host 170.207.144.198.in-addr.arpa. not found: 3(NXDOMAIN)
$
That's from a block owned by Raw Bandwidth Communications.
http://whois.arin.net/rest/net/NET-198-144-192-0-1
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 198.144.207.170. 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.
