[Mailman-Users] Mailman and virtual mailhosting (postfix)

[Jens Meyer]

Hello Mark,

thank you for your further reply.

The problem are not the virtual hostnames or the "advertisements" of the 
listnames.
My problem is the internal handling:

Is it possible to change Mailman's internal usage (target for internal 
redirections) from @hostname.com to @mail.hostname.com (because 
@hostname.com is used for virtual emails on this server actually).

Kind regards,

      Jens
