Anti-spam measures

Andres,

You have some very good ideas, which if concensus could be reached
would help a few years down the road.

I think most of your ideas a worth persuing and RIPE would be a
good forum for doing so.

I have been thinking about something much more easily implemented:

Participating ISPs adds a TEXT record in DNS for the IP numbers
of all their dial-in ports which say

	W.X.Y.Z.IN_ADDR.ARPA.	IN	TXT	"NOSMTP"

Sendmails refuse email from such IP#, unless specifically instructed
otherwise (ie: at the home ISP of the ports).

How is that for a short term solution ?

This allows responsible ISPs to clearly signal to the rest of the
net that "Don't trust this guy for SMTP".

If we could get UUnet, sprint, ibm.net, compuserve.com and so on
to add those records, then life would be much easier over here...
