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 188.8.131.52 but couldn't resolve
that to a PTR record, therefore `unknown'.
$ host 184.108.40.206
Host 220.127.116.11.in-addr.arpa. 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 18.104.22.168. 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.
