We have linuxed based qmail email server and are using secure pop mail. I created a certificate using my own ca for this. To avoid users getting the annoying message about a certificate from an untrusted authority when then check their email from outlook I have been physically going to each machine to install our CA's certificate as a "Trusted Root Certification Authority". Is there some way to automatically push this through the domain using group policy or some other way so that I don't have to go to each machine and be signed on as the user and import the certificate?
We use Window 2003 Server for our domain controller and we also have SMS.
