Stopping Spam

Spam is a name given to unwanted or unsolicited e-mail (also sometimes referred to as UCE or Unsolicited Commercial E-mail). This type of e-mail generally contains advertisements for such things as a better mortgage rate, amazing prices on non-prescription drugs, or adult websites.

There are many reasons why you might receive spam. Signing up online to get anything "free" will normally cause you to be added to a spam list. Having your e-mail address available anywhere on the web (like on a web site or message board) can cause you to be added to a spam list as well.

Symptoms of Problems

  • Receiving unwanted e-mail

Recommended Solutions

If you are already receiving a lot of spam, and want a way to filter it out, there are quite a few programs available to help you. Many of the virus scanner companies, including Norton and McAfee, have email spam software built into their Internet suite programs. If you already have one of those suites make sure email filtering is enabled.

A popular and well rated free program for Windows-based computers is Cloudmark Desktop One. The free version is suitable for a single email address, wtih a pro version available for those that need more options. A commonly-used program for the MacIntosh is SpamSieve. Both of these programs are excellent low-cost spam filters that will work with your current e-mail programs to help get rid of unwanted e-mail


Unfortunately there is no way to completely prevent spam; however, there are a few things you can do to slow it down.

  • Only give your e-mail address to people you know. The fewer people to have your e-mail address, the lower your chances are of it ending up on a spam list.
  • Never click on a link to unsubscribe yourself from a spam list. Doing this confirms your e-mail address and tells spammers to send you more unwanted e-mail. Instead, use your email program's filtering abilities to block/delete messages from that sender.
  • There is currently no officially recognized "do not spam" list. Signing up for a supposed do-not-spam list is likely equivalent to saying, "Yes, please send me even more unsolicited mail."
  • Use your company e-mail address for business use only.
  • Never post your email address online where it is visible on an open web page. An example would be posting your email on a forum. A related example would be a forum that shows an email link or your address as a standard part of your posts. Robots scour the web looking for email address to add to their spam databases.
