This would result in testing every host that sends you email.
Worse, if such a scheme becomes populare it'll result in every
host that I'm sending a message to testing my server. Not fun
when you're running mailing lists ;)
IMHO such a testing scheme should be distributed, we should
share each other's results so we waste less resources doing
the various tests.

For the positive hits, there already is a distributed system,
it's called the Distributed Server Boycott List, DSBL:
It has a set of testing programs available at
For the negative side of things, ie. determining which servers
have already been tested by others, there doesn't seem to be
anything available yet. You've made me think about the issue
though and I'm convinced now that we'll want something.
Bravely reimplemented by the knights who say "NIH".
