When you open Mail on your Mac you see a warning message:
Mail can’t verify the identity of “mail.domain.com”.
- Check Always trust “mail.server.com” when connecting to “mail.domain.com”
- Click Connect
This will make the warning message disappear, however the message will appear again when the mail server’s SSL certificates are next updated.
To permanently fix the error change your Mac’s Mail settings to use your Ecenica package’s SSL incoming and outgoing servers for your Ecenica email account.
See How-to Enable SSL Email in Apple Mail for steps.
