Dear Customer,

As a part of our regular maintenance, we are updating the renewed SSL certificates on our mail servers i.e.,, and Once the new SSL certificates are updated on our server, you need to accept the new certificate in your email clients.

However, on iOS/MAC device, you will receive the pop up message as "Cannot Verify Server Identity" in email client as Apple does not consider the alias names safe when the SSL certificate is installed for server hostname. In order to fix this issue, please refer the KB article here:
