I haven't played with the latest release sendmail, but if SSL and SASL are easier to turn on, that's a great start. I don't think anyone with a brain has been sending unencrypted email across the Internet, except possibly iPhone users, for whom installing a self-signed certificate seems to be impossible (if anyone knows a method that's simple enough for a fanboi to understand, please tell me!)
