I did get the upgrade through the link you provided. Thanks!
However, I have not changed my email address and there are no spam blocks keeping MTU email from reaching me. The only thing I can think of is that my ISP will not accept mail if Reverse DNS is not configured for the mail server sending email to us. Could that possibly be the case, I can't think of too many other reasons.
Could a test email link be set up for MTU customers to verify we can communicate with MTU so we can be sure to receive notices for maintenance releases?
And Thanks for all of your support, Hoster is an awesome product!
