[Mailman-Users] adding list on virtual domain

[Anne Ramey]

I want to change a list I added to the main domain on the list server to 
  the equivalent of having added the list as listname at www.myotherdomain.com
I would have thought this was the preferred domain variable in the 
general options, but it's still taking me to 
http://maindomain.com/mailman/admin/listname/members etc instead of
http://www.myotherdomain.com/mailman/admin/listname/members

?
