Actually, encrypting outgoing email is automatic if the proper plugin is enabled on your email client...like Voltage for MS Outlook.
You do not have to be very tech savvy, there is not much to it. I don’t know specifically about the IRS but if you are using a DoD computer, encrypting your email is very easy using your CAC. I believe that it is an option with any gubmint computer.
