Thanks Viralrathod, that worked. 
 
I didn't get a reply for a while and thought I figured it out myself. I did create a new receive connector and tried to run the; 
Get-ReceiveConnector newconnectorname | Add-ADPermission -User &quot;NT AUTHORITY\ANONYMOUS LOGON&quot; -ExtendedRights &quot;ms-Exch-SMTP-Accept-Any-Recipient&quot; 
 
on it but got an error so just disable to connector and hoped someone with al least half a clue would post the answer ;-) thanks.
