Thanks for all the replies.
To respond to some points made...
The IP is dynamic, and has changes twice in 8 years. So an hours
TTL is OK. And yes, I did find problems sending email from jupiter
because its a dynamic IP.
From - ian(a)ianhobson.com
To: ian(a)ianhobson.co.uk
This is the critical section of my log file... (which I don't understand).

It appears to show that my email address was bounced because it does not
exist (it does) and then it can't deliver the bounce! I'm out of my depth.
I can find nothing in the logs on jupiter that matches. qmail has
nothing to match. All maillogs are empty.
Suggestions anyone?
Ian
