Secure wireless email on Mac OS X: “Know what happens to your usernames, passwords, and personal email messages when you use public wireless networks? Know that this data often travels freely through the air in clear text? And do you know how dead simple it is for anyone else on that same network to intercept your information and use it against you? On the flip side, did you know you can scramble this data to make it completely unintelligible, even if someone else does intercept it?”
