That's right. Then the MTA returns a bounce to testlist-bounces for each 
undeliverable address.

If there's a bounce.

Aha! DEFAULT_EMAIL_HOST controls the domain exposed to the world for 
mailing TO Mailman. It has nothing to do with what domain we connect to 
for sending from Mailman. That is controlled by SMTPHOST which defaults 
to 'localhost'. I'm assuming that domainmta1 at domainpriv.gov above is a 
typo and you mean domainmta1.domainpriv.gov or maybe 
domainmta.domainpriv.gov since that's what you seem to actually have for 
DEFAULT_EMAIL_HOST. So assuming the Sendmail you want to send (not 
receive) through is domainmta.domainpriv.gov, you want

SMTPHOST = 'domainmta.domainpriv.gov'

in mm_cfg.py.
