The server sits on  a private network and is being NATed to the outside.
The adsl router is doing this Netcomm NB1400. Inbound I have let 110/tcp
and 25/tcp through. I have told the router which machine to resolve
these packets to which is my mail server. Anything can get out.

Sorry about being a bit security consicene. But if you would like to try
the ip of the machine in question (well the IP I have being assigned)
203.219.50.38. You well get through on port 110 but not 25.

I was doubtful of the DNS. There is another worry in that I can send
mail to this address and it seems to disappear into a black hole there
is no bounce!

Thankyou for all of your replies.I will try the suggestions tomorrow. 

Jeff
