Hello Gavin,

Thank you for using Apple Support Communities.

I understand that you are getting the message "cannot verify server identity" error message on your Mac mini. I would refer you to the following support page from the Mail User Guide addressing how to verify this info.

Best regards.

So, there isn't any possibility to check and trust any license or certification 😟
