In the past, I have talked with spamcop folks about SPF issues. They
may well be willing to make some changes. It may be very possible
that they would be willing to publish "v=spf1 -all" records on the
domains that are used exclusively for spamtraps. I think it is highly
doubtful that they will be willing to stop counting backscatter as a
listable offense.
Ok, I will request that. I wonder if spammers would simple stop forging
domains with -all? I suppose that would be a good thing...
In my book, a DSN is not backscatter if the sender provides no way
to recognize forgeries.
When I reject at SMTP time, legitimate senders never see the entire
error message - because their MTA mangles it. The DSNs are very helpful
to legitimate but clueless senders - and also serve to verify that the
sender actually exists. Of course, if I knew who the legitimate senders were,
I wouldn't need to send a message ...
