When you access your email in Apple Mail on macOS the following error can occur:
The identity of “mail.example.com” cannot be verified.
The certificate for this server is invalid. You might be connecting to a server that is pretending to be “mail.example.com” which could put your confidential information at risk. Do you want to connect to the server anyway?
- When you open or send and receive email from Mail on macOS the error is shown.
Apple Mail cannot verify the SSL certificate of the incoming or outgoing server and create a secure connection. This may be caused by your Apple Mail using incorrect email settings.
Check your incoming and outgoing server names are set correctly in Apple Mail on macOS.
