Thanks for the Per,

bed-11.uk.clara.net seems to host our website, or at least the CNAME
for www.praybourne.co.uk points to this server. Yes we use mailertable
to point praybourne.co.uk to our exchange server [praybourne.local] we
also use procmail to filter spam and archive all incoming email. All
this has not been changed from when we was with our last ISP, and all
worked fine then.

I have done as you suggested, both with our internal DNS servers, and
then using our ISP's (not sure if it would make a difference)

Using internal DNS:
> sendmail -bv david.greenhall@praybourne.co.uk
david.greenhall@praybourne.co.uk... deliverable: mailer procmail,
host /etc/mail/procmailrc-praybourne.co.uk/procmailrc, user
