OK. I've finally found the last problem.
I had, for some strange reason, set LUSER_RELAY in the sendmail.mc on 
the internal server, to point to the external server. Once that was 
removed, and I added the renaming host line as previously suggested, all 
was well.

Thanks everyone for all the assistance.

Cheers
