Allowing users to set their archive preference in their list settings is 
a completely different feature.  If someone wants to write a patch that 
does that, it should act on incoming email before mailman processes that 
mail for local archiving so that the local archive honors the user's 
setting.  Then the list archive process would happen after the local 
archive is written.

Personally, I don't see this as a big problem.  If the header is 
inserted at a single specific place in the stream that is OK *as long as 
it's properly documented*.  Then each list server admin or list owner 
can choose to turn this feature on or not, knowing exactly what it will do.

IMHO, the correct place to insert this header is after mailman has 
processed the incoming message and archived it locally.  That way the 
original sender's x-no-archive setting (set in the original incoming 
email or by the *other* x-no-archive patch that might someday be added) 
is correct for the local archive, and the outgoing mail is correct for 
the list's preference.
