Don't expect too much of it. CF can not handle all unicode encodings,
so cfpop will fail on quite a few emails.

4xx = temporary failure
5xx = permanent failure
The first 80% or so is easy to identify reliably, then it gets harder,
especially with localized mailservers.

You could, but you might also include an identifier header, quite a
few mail servers return all headers.
