A few other tips:
For added protection, use web based email only, such as hotmail or yahoo, but without the pop3 feature. Not only do they scan email for viruses, but the email resides on their computer, not yours. Additionally, you can access it anywhere from the web while away from your own computer. If you want to save something long term, download it to your computer.
Don't even let Codetel (or any other provider) into your house. If they are so anxious to get at your computer that they refuse to simply take your money and give you the logon information, find another provider. If there is no other and you're stuck, try to find an excuse to make them do it your way. Since Codetel wants to put you off for 3 weeks, for example, tell them that you can't wait that long and will set it up yourself.
Don't run anybody's CD to set up your account, and don't use their pop3 email at all.
Have a throw away email account for "free" offers, internet buying, DR1 profile, etc.
Ask your friends to never ever "forward" anything from you to someone else because it carries with it your address, which you don't want anyone else to know of course. If they like one of your jokes so much, ask them to please cut and paste it into their other email.
