Thanks for the correction... "MTA='Postfix'" works
just fine.

However, no change in mailing behaviour after making
this change and
restarting mailman/postfix.  I still can't get
messages out beyond the
local network.

Note that up to this point, I have put the aliases for
mailman lists in
/etc/aliases and have only created lists via
command-line interface. 
Also, I observe that there are no data/aliases or
files.  Do I need to create these?
