Hmm tobe honest it seems that the mail adress list is skiped totaly
This works since it reads the STORE_OWNER_EMAIL_ADDRESS and not from the email list...
tep_mail(STORE_OWNER, STORE_OWNER_EMAIL_ADDRESS, $emailsubject, $enquiry, $name, $email_address);
BUT
There is no Email Subject: (from the list) as subject it only says "Enquiry from THE COMPANY NAME"
