Identified
Users who have mail clients on Apple devices are likely to encounter an SSL Certificate Trust Warning when connecting to our mail servers using an aliased name such as `mail.youdomain.com`. This may be preventing you from connecting our mail servers to send/receive emails.

To get around this, you should connect to your mail server using its actual hostname, which will be something like `mail123.extendcp.co.uk`. This can be found in your control panel.

Alternatively, you can add an exception to the SSL Certificate via Keychain.
