How can I disable MX verification?

[jplethier]

I am getting an error that when I try to verify a valid email from crepelocks.com.br,(eg [email protected]) I get NoMailServerException, but this is ocurring because the crepelocks dns was configured in a wrong way, but the email is real and exists. I already send an email to this and it works, and using http://www.verifyemailaddress.org/ the verification says to me that this email is valid.
