hostname in smtp.helo()

[Emile van Sebille]

The RFC's don't require validation of the domain argument.

Recently, AOL started performing reverse name lookups and
matching to the IP address of the sender.  If this failed,
they rejected the message.  Other than that, the HELO is
more for synching than anything else.
