I am having some issues with a Geotrust certificate that I purchased today...

I have an SSLQuick Premium Certificate, and I am trying to use it to send/receive e-mail securely with Outlook XP. The certificate works fine through the web browser and through Outlook, when I use it as a web browser, but when I use it for mail, I receive a message stating the certificate is not trusted.

Has anyone experienced this problem before? Any suggestions?

Thanks for your help...

QuickSSL is an intermediate certificate, so the intermediate cert needs to be installed properly on the mail server.
What kind of mail server are you connecting to?

The server is running CPanel, so I am assuming it is using sendmail as the mail server.
