 -The list server adds a signature.
 -does not remove the existing signature,/
 -does not modify the message

A) the mailing list server adds a signature i= (signer) and "From:" are 
different. The signature may be invalid if the sender SSP does not allow 
third party signature.

That's a good argument why the Lists's signature should not cover
the FROM:  etc. headers with the poster's address, but be limited
to the message headers that identify the List itself.
