OK .. ran both tests as mailman. First one was fine. Second one, while 
it shown no errors initially, I only received the email that was sent as 
a rcpt (secondary email address). The To: email address did not get 
delivered. The smtp-failure logs do not show a specific error for that 
email transaction but it still shows a ton of the same errors, i.e.:

May 29 16:21:04 2009 (6489) Low level smtp error: (-2, 'Name or service 
not known'), msgid: <mailman.1.1243617046.6486.someone at domain.net>
May 29 16:21:04 2009 (6489) delivery to someone at domain.org failed with 
code -1: (-2, 'Name or service not known')

Both /etc/resolv.conf and /etc/hosts are world readable. I am truly stumped.
