Receiving email locked out for security reasons. Need reset.

​?I was receiving security emails from Xfinity but was unable to update my email program before getting locked out.?​

​?Now I can send emails but can't receive emails.  I have sense upgraded to a newer version of the email program that another xfinity user tells me works and that the security check validates as OK. Could someone help me remove the lockout so I can continue to use my email program?   Or at least get back to the state that I can validate the updated email program?​

​Note:  I can still send from the updated email program and when I send to the security test email address the response says it passes the security test. The problem is I have to use another email program to see the response because the mailer is locked out from receiving emails.  I'm really hoping I can get this fixed quickly, please.​
