Due to the Heartbleed bug we have changed the SSL certificates used on all our servers recently. If you used the mail (e.g. mail.example.com) subdomain when configuring your email client, because the certificates have changed, you will see a notification prompting you to accept or trust the certificate; just like when you setup your email client. Your Email Client (Mail, Outlook, Thunderbird, ect. ) will show you an error similar to:
"The server you are connected to is using a security certificate that could not be verified. A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider. Do you want to continue using this server?"
There are two ways to resolve the issue, you will either need to trust the SSL Certificate or use the servers hostname as your server, e.g host7.server.ae (depending on your hostname).
