I have a Windows 2000 / XP network. I use Eudora as mail client and SLMail as mail server.
I need to implement an sMime encryption on 5 machines (not all). I have found that Eudora does not support this feature, neither there is any graphical plugin that a standard user could easily employ (command line plugins are not useful in this situation). I do not want to move towards Outlook / Exchange: there are cost and security concerns involved. I would like to install some kind of solution that could allow the users to selectively encrypt mails, and add a certificate to them (I cannot encrypt every mail, because I do not know if the adressee would be able to decrypt them).
Do you know of any way to add encryption + certificates to my current configuration?
Additionally, I have a related issue. As I only need 5 certificates, I have contacted VeriSign and Thawte. VeriSign told me that they only issue certificates in pack of 10 or more. Thawte give the certificates for free, but the kind of certificates given is absurd. It is a personnal certificate that somebody else must check in what they call "circle of trust" (or something similar). Obviously, this is not the kind of certificate that a company could use.
What can I do? Any ideas would be appreciated
