[Mailman-Users] Mailman Changing real_name Variable in welcome message subject !

[Nuno Gonçalves]

Hi all,
 
I am looking a way in order to change the subject of the welcome message.
In the file in [Mailman home directory/Mailman/Deliverer.py] (line 79) there
is a line :
_('Welcome to the "%(realname)s" mailing list%(digmode)s')
 
Is there anyway of subtituting the variable realname for one in the
acceptable aliases list (the firts one for instance)?
Is there any variable acceptable_aliases (confs/list.conf) accessable in the
Deliverer.py ?
 
The objective here is that the list address alias is in the subject line
instead of the list realname.
 
Any hint is appreciated
 
best regards to you all
