I have a medical office that needs to send encrypted email to comply with HIPAA requirements. I don't want to get sidetracked with all of the HIPAA compliance stuff, I just want to give them what they requested, which is a way to send encrypted emails WITH MINIMAL REQUIREMENTS FOR RECIPIENTS TO RECEIVE AND VIEW SAID EMAILS. That's their emphasis, not mine :-) I looked at free service from sendinc.com, but that requires recipients to create an account. Using the security built into Outlook with a certificate for example, I believe requires the recipient to also have a certificate, which won't work, assuming I have that right. I know this is possible because my own insurance company sends me encrypted emails which I can open without any fuss. I probably had to do something up front to allow this, but I don't recall what it was. The client's environment is Outlook 2007 using godaddy.com domain based pop/imap email. Ideas? Thanks!
