Which will probably be a valid host name and resolve to an IP. So the
email shouldn't "bounce with configuration complaints about a
non resolvable domain name."

His email didn't indicate that the problem was having an hostname that
resolved to an IP that resolved to a different hostname (like the paranoid
tcp_wrapper check). Of course, he didn't provide an example of the exact
error message either.

If using a valid hostname (via a dynamic DNS) and valid IP (as assigned
by his ISP) which resolves to some hostname, it seems like everything
should be okay. (At least, that has worked for me on a couple systems for
over a year.)
