If the server is handing out its hostname, then it's fine. You just need
to set a proper hostname (fully-qualified and one that exists in DNS).

Also, FYI, Norton anti-virus gateways need to be sandwiched between two
regular servers. They can not handle MUAs or Internet MTAs on either
side. This is one of the major reasons we switched off our Norton
filtering solution a couple years ago.

If he's blocking because the domain you're sending *isn't fully
qualified*, he's fine. You're broken.

If he's blocking because the domain you're sending *doesn't resolve*,
he's fine. You're broken.

If he's blocking because the domain you're sending *doesn't resolve to
the IP address of your machine*, he's broken. You *might* also be
broken.
