[Asrg] Feedback to MTA



Hi,
I recently subscribed to this list because spam is increasing. Some weeks ago some 
idiots started sending mails to johndoe at <mydomain>. Now about 50 to 100
per day. Easy to filter these invented addresses but nevertheless my money
as long as I don't have a flatrate.
Please apologize if I have wrong ideas sometimes because I'm just beginning
to have a look at this whole mail problem.

I recently was also thinking along these lines to give feedback because AFAIK
the IP of the sending MTA is nearly the single information in a mailheader I
can trust.
OTOH it's probably not enough. If this is a zombie the reject will go to the
zombie which doesn't care.
Perhaps every mail should have a <abuse-to> field which must contain an
"abuse" MTA name which I can report abuse to. And to make things for spammers
harder this MTA must match the sending MTA in the first 3 octets.
And if I reject a valid mail because it doesn't has a valid <abuse-to> this
will go back to the real sender who can then select an ISP which follows this
protocol.
And in addition governments could set up some let's say <federal-to> addresses
to which a spamreport (Being spam decided by the receiver) which consists just of the
header data, will go.
Wouldn't that be a nice idea for George W. B. and Gerhard Schröder ?
Just some ideas. Tell me please why it won't work :-)

Cheers, Edgar
