[Mailman-Users] host vs alias (CNAME) and listinfo

[Marek Kozlowski]

:-)
If you compare:
http://alpha.mini.pw.edu.pl/mailman/listinfo
http://www.mini.pw.edu.pl/mailman/listinfo
you will see different public lists. The "www" is a CNAME od "alpha" so 
this is the same host. When creating a new list there is no hostname 
choice (AFAIK). In the administration panel I can't see this option too. 
What is the source of this difference?
Best ragards,
