Yes, of course. But a single mailman installation hosting multiple mailing 
lists already has the complete knowledge, does not it?

Yes, absolutely -- the only key is Message-Id. Even if a hash of the message 
body /could/ be used as the key, I think, a different Message-Id means, the 
message should be sent again.

I think, this function is already here. When I first sent message to this 
list, it bounced, because I was not a subscriber. The bounce suggested, that 
I subscribe ALL of my addresses and mark some of them as "NOMAIL". This would 
seem to indicate, that multiple addresses-per-person feature is already 
established.

This is true. But if /most/ duplicates are eliminated by this, then the 
remaining /few/ may be acceptable to allow cross-posting to relevant mailing 
lists.

AFAIU, the message will appear in the search results multiple times -- once 
per mailing list. That is not justified -- the results should contain no 
repetitions...
