Hi Jeff, You've understood me corectly. I made a few phone calls 
yesterday and discovered that the people who own the domain have 
apparently failed to renew it. Its no longer a valid domain name.

Before I discovered that I thought that there -may- have been a DNS 
failure and it -may- have been possible to address the mail to their IP 
address bypassing the DNS. I was sending mail from my account to the 
address name@[my ISP's SMTP IP address], not their ISP's SMTP IP 
address, which I cannot obtain anyway. My MTA sent the mail OK but it 
bounced back with the error I posted earlier.

I haven't achieved my objective, for obvious reasons, but I have learned 
a lot thanks to everyone who helped me. Who said you cannot teach an old 
dog new tricks?

Thank you to everybody.
