Now the HR department wants to be able to send encrypted emails (TLS/SSL) emails amongst themselves and to outside sources. Each of these people are using outlook 2003 as their email clients.

What is needed for the HR department to send the encrypted emails? Currently Enable dedicated ssl listener and enable TLS is enabled for imap, pop3, and smtp.

I've tried many different variations to no avail. We're using a self signed certificate on the email server. I tried installing the certificate (via IE), setting the outlook to ssl on both pop and smtp.

From what I can see, I need to get a digital ID for each of our users that need to encrypt email - correct? And possibly a certificate from a trusted root like Verisign?

An inquiring mind wants to know.
