imo this really isn't something that belongs in mailman, you start getting into all kinds of nasty hueristics ... if you belong to two groups and a message is cross posted which group do you favor and give the message too? It just gets worse as you add groups. Do you addresss that by taking the intersection and making it look like it only comes from one address? Do you let each user decide?
Well, I figure this isn't THAT hugely common, which of course asks, why do it, but regardless... anyway, the user gets the copy that first shows up in th mailsystem... which basically would be whichever one is listed first in the recipients list from the MTA's perspective.
THat's not relevent, underneith it's the same information. You don't munge anything in the headers, you just adjust the recipient list for the outgoing message (RCPT info), and you deal with it again when 2 copies come in again. I don't see any other way to fdo this.
Yes you could decide on a per user basis (make duplicate-supression an option, turned on by default, I suppose).
It would seem better addressed as another list adminisitrator concern. You could help them I suppose, give them the ability to say, "list a and b will not accept crossposts from one another" but generally its probably enough that they gentley remind their users when it occurs excessively.
I think this is a seperate issue, though obviously related. Sometimes you do want x-posts... sometimes you don't, that should be an option.
Just my handwaving Chris
