Good tutorial but its does not make it fully secure. SMTP is an unsecure protocol, so if your host decides or is compelled to sniff the traffic, all emails received or sent could be recorded in plain text. Not to mention emails from senders using 3rd party services are already compromised even before it gets to you. How is it that we still don't have proper support for secure SMTP among most email providers?
