As a practical matter, 'bar.mime-type' had better be a proper DNS entry, or
a lot of places that do a "is the address at least putatively returnable?"
test (which *should* be essentially 100% - does anybody *not* check this?),
they will find it won't go very far.

As a second practical matter, I suspect that all the places that have already
decided that '*.biz' is a cesspool will be even more dubious accepting mail
from 'foo@bar.application.octet-stream'.

I'm still trying to figure out if this was for real, or if it was intended
to be posted 2 weeks ago and ICANN bureaucracy delayed it... ;)
