Why don't you use email encryption?
mdasen: Why don't we use HTTPS for everything we send over the internet?  Why don't we have locks on on all our mailboxes?  In fact, the post is just terribly insecure.  Heck, plenty of people who live in more rural areas don't even lock the doors to their house.There are lots of reasons, but when you get down to it, we just don't care that much about security.
