Mail can't verify the identity of the server macbook
A common issue!
When your MacBook can't verify the identity of the server, it's usually due to a certificate issue. Here are some steps to help you resolve the problem:
- Check the server's certificate: Ensure that the server's certificate is valid and trusted. You can do this by:
- Opening the Keychain Access app on your MacBook.
- Selecting "Certificates" in the top menu bar.
- Looking for the server's certificate in the list.
- Checking the certificate's expiration date, issuer, and subject.
- Verify the server's identity: Make sure you're connecting to the correct server and that the server's identity is correct. You can do this by:
- Checking the server's hostname or IP address.
- Verifying that the server's certificate matches the expected identity.
- Update your system's trust settings: If the server's certificate is not trusted, you can update your system's trust settings to include the certificate. You can do this by:
- Opening the Keychain Access app.
- Selecting "Certificates" in the top menu bar.
- Right-clicking (or control-clicking) on the untrusted certificate.
- Selecting "Get Info" from the context menu.
- Clicking the "Trust" tab.
- Selecting "Always Trust" from the "When using this certificate" dropdown menu.
- Check for certificate revocation: Ensure that the server's certificate has not been revoked. You can do this by:
- Opening the Keychain Access app.
- Selecting "Certificates" in the top menu bar.
- Looking for the server's certificate in the list.
- Checking the "Revocation Information" section.
- Reset the System Keychain: If none of the above steps work, you can try resetting the System Keychain. This will remove all certificates and trust settings, so be sure to re-add any important certificates after resetting. You can do this by:
- Opening the Keychain Access app.
- Selecting "Keychain Access" in the top menu bar.
- Clicking "Reset the Keychain" from the "Keychain" menu.
- Contact the server administrator: If none of the above steps resolve the issue, it's possible that the server administrator needs to update the server's certificate or configure the server to use a trusted certificate authority.
By following these steps, you should be able to resolve the issue and verify the identity of the server on your MacBook.
