My company recently had to update our web cert with geotrust and the format was webmail.mycompany.com
however we had some internal dns names linked in with the cert and due to legislation we were told that internal fqdn were not allowed. we now have all over the place the following error ( picture attached).
External access to the email server is fine but the errors are all internal.
Help Would very much appreciate instruction on how to maybe reissue the internal certs ..
