Perhaps. Although, I don't believe that it would be a resend, since a
spambot just needs to prep the receiver with HELO, MAIL FROM, RCPT TO,
without even planning to send data. Unlike outfits like the ASF, for which
the impact could be significant, unless they were added to whitelists. The
ASF spends over a million e-mails per day, and being widely greylisted would
be an issue, since we'd have to spool real messages and retry them, unlike
spammers, who could just pre-train the intended victim.

Personally, I would support disconnecting from the Internet all countries
that don't police spammers. In many ways, that is already happening, as
countries like China find their entire IP allocation in DNS block lists.
