This is a edited copy of the headers I have removed all the email addresses for obvious reasons :-), (is it safe to post the full header?)

To avoivd confusion, my setup is
MyDomain.co.uk -> pw at spamcop.net -> MY MAILBOX at ntlworld.com


I've changed :
<MY DOMAIN, WHICH FORWARDS TO MY MAILBOX> = my domain name
<SENDER'S ADDRESS> = well obviouse really.

This is the second time this has happend, needless to say it works on a further re-try.

Messagea is as follows -

Hi. This is the qmail-send program at blade4.cesmail.net.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<pw[at]spamcop.net>:
This message is looping: it already has my Delivered-To line. (#5.4.6)
