PGP Encryption

Did you know that anyone can find your name, address, and phone number, with nothing but a simple whois search for your domain?

Pop-based e-mail is inherently insecure, since it is sent over the Internet as what is called "plain text," meaning that anyone that happens to be between you and the server, or between our server and the recipient's server, or between them and their server, can read your message, regardless of whether or not you logged in securely. There is an option:

PGP encryption- uses a series of keys and codes to convert your readable message into absolute gibberish, so that even if someone captures and reads your message, all they'll get will be an unreadable string of random-seeming garbage. The person receiving your message then uses another key, which you already sent them (this really only needs to be done once, since your key is pretty much a permanent thing,) to decode the message and read what you sent. The problem with this method is that it only works as long as both you and the person to whom you send the message are using a program that is capable of using PGP encryption; at this time, Outlook doesn't natively support OpenPGP (the free, open-source version), although you can purchase a certificate from several providers that Microsoft has partnered with; you can see this by opening the Options window and looking at the Security tab within outlook. You can read more about PGP and mail clients/ad-ons that support it at the referenced links.
