Many email apps now enable SSL or TLS encryption by default, ensuring that your email login information and traffic are securely encrypted before being transmitted over the Internet.  This ensures your data cannot be intercepted or tampered with by untrusted third parties.

In order to properly use an encrypted connection, you need to have your email app settings exactly match the names we use on our security certificates.  Some apps, mainly Apple IOS devices, will not allow you to use an encrypted connection unless the settings for your email server hostnames exactly match our certificates.

You can use this guide to look up which server address you need to specify in order to set up a trusted encrypted connection and you then need to update this in your email client/app account settings.
