Tip of the trade: e-mail encryption
When you send a clear text, unencrypted e-mail, you are saying "I don't care who reads the contents of this message, I don't care if someone possibly alters the contents, and I don't care if someone else pretends to be me." Doubtless it is not your intention to say these things, but it is an unfortunate fact of life that this is the result.
Ordinary clear text e-mails can be intercepted and read by anyone with access to the wires between you and your recipient. This could be snoopy sysadmins, or anyone who has successfully compromised a server, router or network. Sometimes getting onto a network is easy - unsecured, poorly-secured and rogue wireless access points are big fat red welcome mats for all the wrong people. Did you know that inside jobs, just like in old-time industries like retail and manufacturing, represent the largest percentage of thefts and unauthorized snooping in computer networks? The numbers given vary, but it's safe to say it's a sizable majority.
