OK - my problem is obviously with something that feeds bin/genaliases.  I was 
interrupted and forgot that this step had problems.  When I run it I get:

Traceback (most recent call last):
  File "bin/genaliases", line 116, in ?
  File "bin/genaliases", line 106, in main
    MTA.create(mlist, nolock=True, quiet=quiet)
  File "/var/mailman/Mailman/MTA/Postfix.py", line 230, in create
    if mlist and mlist.host_name in mm_cfg.POSTFIX_STYLE_VIRTUAL_DOMAINS:
TypeError: 'in <string>' requires character as left operand

In mm_cfg.py:

DEFAULT_URL_HOST   = 'www.univexsystems.com'
DEFAULT_EMAIL_HOST = 'univexhosting.com'
MTA = 'Postfix'

univexhosting.com is in my postfix virtual db and is receiving mail happily.

Does that clarify anything?
