ChoiceMail Free

Due to antispam legislation, unsolicited e-mail isn't as big of a problem as it was a few years ago. Still, spam is prevalent, and it's just as annoying as ever. If you're using Outlook Express as your primary e-mail client, make sure to get your hands on ChoiceMail Free, which blocks spam with a challenge/response methodology. Under this system, all your contacts will have to verify their identities to correspond with your e-mail address. This may initially seem like a hassle, but it's not really a big deal, and it all but guarantees that unsavory bulk e-mailers won't find their way into your in-box.
