To BILL in the UK re FSNavigator

Sorry to use the forum in this way but Bill sent me a normal e-mail today requesting information about FSNavigator.I tried to respond but my server rejected my e-mail response saying the address was an illegal host or domain.I just wanted Bill to know that I did not ignore him and that I tried to respond but was unable to do so to the e-mail address he sent his original message from.Bill - if you can use another address please try to contact me again or check with your provider to see why your address is considered illegal.
