Spam has gone way beyond just an annoyance. It is now a time and productivity thief.

If you use Microsoft's Outlook or Outlook Express for your e-mail, here are three simple "rules" you can put into the program that (at least, for me) trap 39 out of 40 unsolicited e-mail's. With these rules, properly installed, spam simply isn't a problem.

If you don't use Outlook or Outlook Express, something similar can be done with other e-mail programs I am sure. If you have AOL, go here to deal with spam.

How Does It Work?

First of all, almost all spam is sent to you as a "carbon-copy" ("CC") or a "blind carbon-copy" ("BCC") message. The first filter rule therefore is to filter out all e-mail that is "copied" (i.e. not "sent") to you. Let's call this rule the "Not Sent to Me" rule.

Unfortunately, legitimate e-mail is also sent to you this way, and the Not Sent to Me rule will prevent that e-mail from getting to you too. This rule, in other words, filters too well.

So you need to save the filtered-out messages in a folder somewhere so that you can look through them once in a while to see if anything important was filtered out by mistake.

Secondly, if you know in advance you're going to be getting CC mail, this mail can be filtered in before the Not Sent to Me rule has a chance to filter it out.

Thirdly, spam tends to contain certain words in the Subject line. If the first two rules don't catch the spam, the third one might.

That's it in 200 words or so. Got it?

Let's lay out a few more details.

Many people participate in group discussions using e-mail. This e-mail is called "listserv" e-mail or "Yahoo groups" e-mail. Listserv e-mail is always sent as "Blind Carbon-Copy" mail ("BCC") so you won't see the other recipients' e-mail addresses when you get the message. One nice thing about listserv e-mail is the "Subject" line always contains an identifying title, something that says "I'm a message from the 'Sopranos' discussion group!"

If the "Subject" line contains this identifying title, filter it in before applying the Not Sent to Me Rule. We'll call this rule the "Discussion Group" rule.

Finally, the subject line in junk e-mail is often about Viagra or getting bigger body parts. A rule can be created to filter out e-mail with any of these words in it, words such as "mortgage," "debt," "sexy," and others. It's unlikely someone is going to send you a real message about having a larger penis, isn't it? We'll call this rule the "Dirty Words" rule.

That's about it. These three rules work for me just fine. Like I said, they catch 39 out of 40 spam messages. Once in a while they filter out a legitimate message, but since everything goes into a "Junk" folder, I can look through it before deleting and recover any mail filtered by mistake.

What follows is a step-by-step procedure (with pictures!) on how to set up Outlook Express to filter out spam. The procedure for Outlook and other e-mail programs is similar.

Warnings

  1. The rules are simple. The steps to set them up are complicated. Read and follow them carefully. It is highly unlikely you will screw up your e-mail program, but I am not so naive as to say you can't. These steps are provided "as-is." If they don't work, or if you screw up your e-mail program, it is up to you to fix it.
  2. It is unlikely I made a mistake in these instructions, but it is possible. Use them at your own risk. I would be happy to install these rules on your computer for you, if you would be happy to pay me to do it. That's what I do for a living, as you know.
  3. Follow all the steps.
  4. Spammers are an aggressive and clever lot. There's no guarantee the nature of spam e-mail won't change to circumvent these rules. So there is no guarantee as to how long or how well these steps will continue to work, or even if they will work at all for you. Keep coming back to this page for tips as e-mail changes.

You might want to print out this entire page to make it easier to follow the instructions. Check off each small step as you do it. Click here to print this page.

Step 1. Create a "Junk" folder

Outlook Express allows you to create "rules" for handling messages. We are going to create three different kinds. Start Outlook Express.

First, we need to create an e-mail folder to hold the suspected Junk e-mail. That way, any filtered messages can be examined later to make sure a valuable one wasn't removed by mistake.

If your "view" in Outlook Express doesn't show your Folders, click on View -> Layout:

Make sure "Folder List" is checked:

Figure 1

Figure 2

and click "OK".

With the Folders displayed, Right-click on "Local Folders," then left-click on "New Folder...".

Figure 3

Figure 4

Name the new folder "Junk?" and press "OK."

The "Junk?" folder should show up in your folders, under "Local Folders".

Step 2. Creating "Discussion Group" rules

If you don't participate in any e-mail discussion groups, you can skip ahead to Step 3.

You will have to examine your Discussion Group e-mail for the text in the "Subject" line that identifies it as that kind of e-mail. I can't tell you what that text will be, but it will be the same name or words every time you get e-mail from that Discussion Group. One Discussion Group I belong to has the text "[FFC_list]" in the Subject of every e-mail they send me. So I have a rule that says "If the Subject line contains [FFC_list]", put that e-mail in the FFC_Inbox and stop processing any other rules."

You need to get a similar text identifier for each discussion group you belong to, and create a rule for each one. For purposes of this example, let's call that text "[ABC]". What it will actually be is up to the group you belong to.

You need to create a folder to hold this "filtered in" e-mail. Follow the steps in Step 1 above to create a folder. Name it something that makes sense to you. For this example, we'll call it "ABC Inbox".

To get to the e-mail rules in Outlook Express, click on Tools -> Message Rules -> Mail...

Figure 6

This opens the Message Rules dialog box:

Click the "New..." button. This brings up the "New Mail Rule" dialog box.

Figure 8

For each "Discussion Group" rule, we want to create a rule that says, "If the Subject of the message contains "your discussion group text", move it to the Discussion Groups folder and stop processing any further rules on it."

Put a checkmark in the "Where the Subject line contains specific words" choice.

Figure 9

Click on the contains specific words link and give it your Discussion Group's particular text. Click "Add." Click "OK".

Figure 10

Back at the New Mail Rule dialog box, put a checkmark in the "Move it to the specified folder" choice.

Figure 11

Click on the specified link and choose the "ABC Inbox" (or whatever folder name) you created at the beginning of this step

Figure 12

Don't Skip This

Scroll down the "Select the actions for your rule" list and put a check next to "Stop processing more rules". This is very important because without it, the Not Sent to Me rule (which you haven't created yet) will filter all these Discussion Group messages into the Junk folder.

Make the name of the rule something that makes sense to you, such as "ABC Group".

Figure 13

Click OK to dismiss the "New Mail Rule" box. Click OK again to dismiss the "Message Rules" dialog box.

Follow the instructions in this Step 2 for each Discussion Group you belong to.

You're done with Step 2 and more than half-way done!

Step 3. Create the "Not Sent to Me" rule

Go back to the Mail Rules section of Outlook Express: click on Tools -> Message Rules -> Mail...

Figure 14

This opens the Message Rules dialog box:

Click the "New..." button. This brings up the "New Mail Rule" dialog box.

Figure 16

For the "Not Sent to Me" rule, we want to create a rule that says, "If the message isn't sent to me, move it to the Junk folder."

Under "Select the Conditions for your rule:", put a checkmark in the "Where the To line contains people" choice.

Figure 17

Click on the contains people link and give it your own e-mail address:

Figure 18

Do not click "Add" or "OK" yet. Click the "Options..." button.

This brings up the "Rule Condition Options" dialog box. Choose the "Message does not contain the people below" choice and click "OK."

Click "OK" to the Select People dialog box.

Figure 20

Back now to the New Mail Rule dialog, in the "Select the Actions for your rule:" list, put a check in the "Move it to the specified folder" box.

Click on the specified link, and choose the "Junk?" folder you created in the first step.

Figure 21

Name this rule "Not Sent to Me" and click the OK button. Your Not Sent to Me rule is done.

Click "OK" to dismiss the New Message Rule dialog box.

Step 4. Dirty Words

"Dirty Words" are words that are likely to mean the e-mail message is spam. I have a few suggestions, and you are invited to come up with some on your own.

Something I've noticed about some of the spam I've seen is it often contains my user name in the subject line, something like "bunkie, how about a lower mortgage rate?" Nobody I know actually calls me by that name, so that's the first "dirty word" I'd search for.

You can be imaginative on the rest, being careful to not over-specify the words to filter out: if you are a urologist, the p-word will actually appear in legitimate e-mail.

Follow the steps as above (e.g. Rule 3) to start building a new e-mail rule. Here's what mine looks like:

Figure 22

Remember to send the e-mail filtered by this rule to the "Junk?" folder you created in Step 1.

Step 5. A Very Important Last Step

You're almost done. The last thing to do is make sure the rules are in the right order. They must be ordered:

  • Discussion Grouprules first, then the
  • Not Sent to Me rule, then the
  • Dirty Words rule.

Using your "new" e-mail program

With all the new folders you've created, things are going to look different in your e-mail program. For example:

Figure 23

Here you see a folder with ABC Discussion Group messages in it entitled "ABC In." There's also a "Junk?" folder with two (2) unread messages in it. You're going to have to click on these folders to see your Discussion Group mail, and you're going to have to look through "Junk?" regularly to see if anything was filtered into there that shouldn't have been.

The "Junk?" folder will get quite full of spam quite quickly. These messages will have to be deleted. Fortunately you don't have to look at all this junk in order to remove it. Simply click on the "Junk?" folder:

Figure 24

...click on any one message there, press Ctrl+A to select all of the messages in the folder, and press the Delete key to delete the whole pack of them.

Again, before deleting all the messages, make sure there isn't something in there that you really want. A quick glance at the "From" and "Subject" should tell you if it's spam or not.

The "Deleted Items" folder will get full doing all this and it must be cleaned up from time to time. Do the same thing with "Deleted Items" as you do with "Junk?":

  • Click on the folder
  • Click on any one message
  • Press Ctrl+A
  • Press Delete

I'll leave the debate on how to rid the world permanently of spam to another forum, but I feel strongly that "your right to wave your arm around ends where my nose begins," and until spam is under control, this will help control it on your own machine.
