[Mailman-Users] Virtual domains

[Merle Reine]

I have our domain setup via mailman and all of our lists work fine.  I 
can not however figure out how to add a second domain to mailman.  I 
need domain2 to be able to have mailing lists.  I edited the mm_cfg.py 
file as instructed and added to main.cf 
hash:/var/lib/mailman/data/virtual_mailman .  virtual_mailman has: 
domain2 in it.  ran genaliases /postfix reload .

When I go to add a new mailing list in mailman, I see no  option to 
select which domain the list should be on.  I want to create
sales at domain2 as a list but see no option in mailman to choose between 
the various virtual domains for lists.

Any ideas?
