[Mailman-Users] Defaults.py doco bug

# If you set MTA='Postfix', then you also want to set the following 
variable,
# depending on whether you're using virtual domains in Postfix, and which
# style of virtual domain you're using.  Set this flag to false if you're 
not
# using virtual domains in Postfix, ...

Actually it has to be an empty list, not false (or False).  I wondered
if that was wrong since false wasn't capitalized, but I decided it
must be a typo and tried False.  Which of course doesn't work.
