I have a client that I would like to upgrade to SBS2k8. They are bound by HIPPA and I would like to know the best approach to securing email with Exchange 2007. Of course, it needs to be as transparent to the users as well as the email recipients as possible. I have noticed a lot of threads on the INternet about S/MIME messages using a purchased certificate from thawte or godaddy etc.
And I'm fine with encrypting all email.
