[Mailman-Users] Reply-to in umbrella lists

[mailman]

Hello,

is it possible to change "dynamicly" the "Reply-to"-Field to the mail address 
of the umbrella list when the mail is sent to the umbrella list and not 
directly to the sublist ?

That is what I mean:

here is the normal case when I send the mail directly to the sublist:

Subject: [sublist] testmail1
From: testuser at domain
Reply-To: sublist at domain
To: sublist at domain


here is what I get when using the umbrella list:

Subject: [sublist] [umbrellalist] testmail2
From: testuser at domain
Reply-To: sublist at domain
To: umbrellalist at domain


but this whould be much better:

Subject: [sublist] [umbrellalist] testmail3
From: testuser at domain
Reply-To: umbrellalist at domain
To: umbrellalist at domain


Thank you

Martin
