When using the email verifier email address's with the suffix .co.uk .com .org .net all work fine. When an email suffix is .fr .de etc the nslookup doesn't see it as a qualified domain name and adds .co.uk to the lookup which returns a false result to the email verifier. I have been tried to use an external DNS as I am on a domain but when this is tried the external domain only sees our domain and also returns a false result. I am unsure of how to resolve this issue as the nslookup is doing what it's supposed to for an unqualified domain name. Is there anything that can be done to resolve this.
