Umbrella list behavior - subject_prefix ; undesired result
All --
I hope this is a quick question about Umbrella lists in Mailman 2.1.9 (sorry about that, not my choice).
If I'm using the subject_prefix setting as follows:
umbrella list: subject_prefix="UMBRELLA>" child list1: subject_prefix="Child1>" child list2: subject_prefix="Child2>"
When I post to the umbrella and I am a subscriber to BOTH child lists, I see:
Subject: Child1> UMBRELLA> Test Post Subject: Child2> UMBRELLA> Test Post
It's not really what I want to see, so I wonder if this changed in future versions of mailman?

P.S. What I hoped to see was: Subject: UMBRELLA> Test Post
In other words, since the messsage has already been through Mailman once, I'd prefer that the subject_prefix for the child lists NOT be used at all. There are times when a post will be sent to one or the other child list alone and not the umbrella, so I would still want a subject_prefix on those messages. If that were not true, I could just skip the subject_prefix on the child lists altogether.
P.P.S. I have read the Wiki on methods to eliminate duplicate delivery. I actually not interested in making that happen right now, just playing with the subject line....

No.

Subject prefixing doesn't take into account the fact that the post came through another list. There are no plans to make it do so.

Mark says no, but it can be addressed using a custom Handler. The main logic is
def process:
if is_a_child_list_of(list, umbrella):
subject = subject.subst(list_tag, "")and the handler should be inserted after the subject header is munged (which happens in CookHeaders, IIRC) but before the message is sent. (Sorry, I don't have time to chase down how to look up the child list predicate or the list_tag at runtime. Maybe somebody else knows offhand.)
I don't think it's a good idea to try to address the duplicates issue on the Mailman side. The messages are slightly different in a way that is important in some use cases, such as replying to one child list.
