What about http://www.spamcannibal.org/?
spamcannibal appears to be a DNSBL that works in concert with a
tarpitting firewall modification. That's nifty, and tarpitting the
connections to the concept under discussion here (which desperately
needs its own thread, as it is a complete departure from assertions),
which could be called mx.nomail.org (nomail.org appears to be
registered by a Czech name reselling service from their whois record,
FWTW) would probably be a good thing. Response time is not that
important; the idea is to draw email connection attempts away when you
don't receive any. Deferring that 550 until the end of the data,
tarpitting and discarding the whole time, could be more effective.
But setting up a mx record to something that does not exist, or to the
wrong mx, for instance mail.ietf.org -- would work just as well, but
would be somewhat rude to the domain you are mxing to.
Collecting the attempts as a spam trap, filter corpus builder?
There's a purpose.
