This should work with the "loops back to myself" message:

myhostname=server1.thecompany.co.uk
mydestination = $myhostname,localhost.$mydomain,thecompany.co.uk,l ocalhost


If it does loop back, until you can find out what's causing it, you could temporarily use:

myhostname=server1
smtp_helo_name=server1.thecompany.co.uk
smtpd_banner = server1.thecompany.co.uk ESMTP $mail_name
