I see two related problems with your DNS setup:
dan> dns_getcanonname: trying m20.example.org. (A)
dan> ;; res_querydomain(m20.example.org, , 1, 1)
dan> ;; res_query(m20.example.org., 1, 1)
dan> ;; res_mkquery(0, m20.example.org., 1, 1)
dan> ;; res_send()

dan> m20.example.org. 1M IN A 216.187.106.227
dan> example.org. 1M IN NS xeon.example.org.org.
^^^^^^^^^^^^^^^^^^^^^
dan> xeon.example.org.org. 5S IN A 127.0.0.1
^^^^^^^^^^^^^^^^^^^^^
example.org's DNS zone has a mistake if it has an NS record pointing to a
bogus hostname like that (and what's worse the bogus hostname resolves).
dan> dns_getcanonname: trying localhost.example.org (AAAA)
dan> ;; res_querydomain(localhost, example.org, 1, 28)
...
dan> dan@m20.example.org... Connecting to xeon.example.org. via relay...
localhost.example.org appears to map to xeon.example.org, perhaps via
/etc/hosts?
My first suggestion would be to fix your DNS zone as mentioned above.
Then, try the test again with more debugging:
echo 'hi there' | /usr/sbin/sendmail -v -d8.8,16.10,61.11 dan@m20.example.org
