Thanks Wietse. I think I will opt for this latter option.
hmm. This didn't work. I'm a bit stuck as to why. I thought that
perhaps it might be running before the Received: header is created, but in
that case, I don't know why the example I linked to earlier that searches
for an authenticated header would work, while this would not.
Geoff.
