[Mailman-Users] List From Name

[James Becker]

I have setup mailing lists for my company to use for regular digests this is
all working fine however my bosses hate the long from name that the emails
come from, I'm talking about the "on behalf of..." part of the from name.
 
I understand that xxx-bounces[at]xxx.com is needed to route back to mailman
but how do I get rid of the "on behalf of..." as in this instance it's not
needed.
 
Cheers
James
