There is one standardized feature for virus and other bounce messages, (which 
isn't mentioned in the original proposal), which I believe would really help:

A bounce should *always* include a MIME attachment of type 
message/rfc822-headers which contains the full headers from the original 
mail. This makes it relatively easy to check on the receiving side if the 
original "Received: from" headers are valid, and simply drop bounces that 
relate to messages that were originally sent with forged headers.


Outstanding idea.  If you (or anyone else on the list) already have a
tested procmail recipe for this, please share.  If not, let's make one
and share it around...


thanks

    Subtlety is the art of saying what you think,
    and getting out of the way before it is understood
