You need to do a DNS MX lookup.  There's nothing in the Python stdlib
which provides this functionality.  There are several libraries available
which do this, though (Twisted among them ;).  You can probably find them
with a little googling.  Beyond that, the rules for processing MX records
are simple and it's not much work to pick the right host once you can do
the MX lookups.
