Hi List,

I have set up SSL on my exchange server which is sitting behind a DMZ wirewall. Incoming POP3S requests are redirected with a NAT rule to the exchange server. Everything is working fine but when i check mail with Outlook or Outlook express i get a warning message that states "The server that you are connected to is using a security certificate that does not match it's internet address" I have searched technet and must be blind or something because i cannot find an explanation for what is happening. I think it's because i'm using my own enterprise root CA but how do i go about telling my workstations that they can trust this certificate? I have tried importing the certificate into my trusted certificates store in Internet Explorer but that had no effect.

Thanks
