I got that a valid DNS name isn't present. What do I do about it. Does
this mean that I need to submit something to my ISP or use one of my
existing email accounts for a name or stick in something from the
returns I get from running host. I know what them problem is. I just
don't know how to fix it. I use Verizon Fios with an M1424WR router if
that is any help.

Well, you were correct about the authentication being a problem. I fixed
it but still no joy. I ran the swaks testing program with: swaks --auth
--to *...@verizon.net --server outgoing.verizon.net.
This asked for the usual login and returned a long list of things. The
last lines were:
<- 235 2.7.0 LOGIN authentication successful.
-> MAIL FROM:<r...@*mycomputer*.domain>
<** 550 5.1.8 invalid/host-not-in-DNS return address not allowed
-> QUIT
<- 221 2.3.0 Bye received. Goodbye.
I understand that my ISP is trying to validate me as a source but am not
sure what to do to fix it.
Host-not-in-DNS means that you have no valid DNS name and when
destination mail system is doing DNS lookup can not verify you, thus
rejecting emails from this source.
Provide valid entry in dns for your mail server and then it should work.
