on its MX.  the majority is spam, but there's always a handful of messages
from people who mistype "" as "", either when sending mail or
when signing themselves up for services (who usually don't do verification).

spamtrapping legitimate personal e-mail that happens to have a mistyped
destination address seems antisocial.  but with's population
numbering in the apparent millions, error theory tells us how many such
mistyped destinataion addresses to expect.  (and it's true in this case.)

therefore before you use whole-domain spamtrapping, i recommend looking VERY
carefully at the flows so that you can be sure that "i" isn't adjacent to
"o" on the qwerty keyboard, or some other such problem.
