[Mailman-Users] lists within lists

[Spyro Polymiadis]

Hi all,

We're running a site with a mailman 2.1.5 configuration with 40-50 lists
on it, and some lists have a list address as a subscriber to the list..

ie the general@ list might have a bunch of individual addresses and an
otherlist@ address also as a member,  (and the otherlist@ also contains
individual addresses)

So, what happens, is that when an email is sent to the general@ list it
gets subject modified [General] as normal, but the people on the
otherlist@ also get rewritten so they get mail that appears as
"[Otherlist][General] Subject line"..

My question is, is there a way to have mailman not include the 2nd subject
tag when posting to the general@ list (for the otherlist@ subscribers)?
but also still retain it when sending explicitly to otherlist@

Cheers
Spyro
