Would it be possible to reduce the spam problem by only accepting mail
for the OpenNIC TLDs and rejecting mail for the ICANN TLDs? Given that
OpenNIC TLDs are not yet as popular as the ICANN TLDs, it would seem
that they would be less likely to get spam.

Also, requiring authentication and limiting the amount of mail per
person that can be sent in one day would reduce the amount of spam sent
further.

I have to use my ISP's smarthost to send mail through port 25. Is DNS
resolution done on my end, or the ISP's?
