Website Administrator Information Error

When I accessed the website editor today I received the following error message.  The address in the site has been the same for two years.  It is a working email address that I use frequently as my primary email address. I had to enter a dummy address in order to update the website.

You have errors in your form below. Please scroll down and correct the following:

1. Administrator Info Tab - You have entered an invalid or non-working e-mail address. (No advertised SMTP servers are accepting mail.) One email address only please, in the form of name@address.com.

If the current address can't be used permanently, we'll need your club number and the email address that isn't working.
 

Club 2015
Email address is info@fayeyoungevents.com

It is the same email address I have been using for years.

The IP address for your email server has been blocked because of hack attempts on the server and the block will not be removed.
