I want to setup Email Encryption for my company so that I can send encrypted emails out. the company is non-profit org so I would like to not spend any money in setting this up. Also I work with alot of gov/state companies as a result of this I was asked to start using email/attachment encryption. I have an exchange server 2003 and I was thinking of setting up S/mime. I have found lots of pointers but nothing definite. I have tried to setup a CA on the server but I don't l know that i have done this right. Basically Im looking for the easiest and best steps to implement this task. This task.
