 Very common in Windows...
when using a self signed certificate because the CA that created the certificate is not in the Root Certificate store in Windows. Since it can't verify the CA it is warning you. It doesn't mean there is anything wrong with your certificate. It may be possible to obtain the CA's certificate from the Zimbra install and import it into the Root Store. This worked in version 4.x.x of Zimbra but I have had trouble doing it with 5.x.x . So I just live with the warning. |
