I have a customer currently on O365.  I will be migrating them to my hosted Smartermail system but I have an issue.  If I create the domain in smartermail in preparation for the migration I can no longer email them as it will deliver locally. Seems odd as you would think it would check for the MX in DNS.  Is there a setting that I am missing that would cause it to deliver locally first and NOT check for the actual mail server IP?

 

Thanks for any assistance.
