Antispam Tools

Category: Spam

Spam is a huge problem on the Internet. For many years now, well over half of all email traffic has been spam. Spam wastes much of the Net's bandwidth, slowing down legitimate traffic. On the personal level, few things irritate users more than unwanted sales pitches. Many spam emails are dangerous bait containing links to malware sites that can steal your identity. You need all the antispam protection you can get. Here are some effective anti-spam tools...

Spam Blockers and Filters

Your email service provider is the first line of defense against spam, and the easiest antispam tool to implement. Spam is filtered out at the email server without ever being delivered to your inbox. It's like filling out a form at the Post Office saying no, thanks, don't deliver any junk mail to my address.

Unlike the Post Office, which makes money by delivering junk mail, email providers are very happy to enable antispam tools because they don't want to waste their resources delivering junk mail to you. So antispam filtering is usually enabled by default on all email accounts you set up. But not always. Some email providers charge a small fee to enable antispam tools. They figure a spam-free inbox is worth some money to you.

What's in YOUR Spam Folder?

If you have a Spam, Bulk or Junk folder that contains junk mail messages, that's a sign that your email provider is doing spam filtering. If not, check with your provider to see what options they offer for spam blocking.

It's a good idea to check the Spam/Junk/Bulk folder periodically to ensure that no mail you really want is getting shuffled off to that antispam pit. If someone says, "Did you get my email?" and you didn't, check the junk mail folder to see if it's there and add that sender to your address book or whitelist. Most email systems that do spam filtering will consider a message to be legitimate if the sender is in your address book.

"False positives" can be a problem with any antispam tool. A false positive is when an email is labeled spam when it really isn't. You can minimize false positives by "whitelisting" the email addresses of people from whom you want to receive mail. Whitelisting tells your antispam tools that this address - or even the entire domain from which desired mail originates - is legitimate and should not be blocked.

Other Anti-Spam Tools

spam filter If you have antispam tools enabled on your email account but you still get too much spam, or if your email provider doesn't offer any antispam tools, consider switching email providers. Google's GMail has one of the best antispam tools available. It automatically traps most spam and lets the legitimate email through.

Most email programs that manage mail on your computer have antispam tools built into them, too. This is your second line of defense. Desktop email programs like Outlook, Eudora, and Thunderbird allow you to create filters that can block email from specific addresses, or block messages that contain certain keywords. Most web-based email providers such as Hotmail, Yahoo and Gmail have filters as well.

For most people, two sets of antispam tools are quite enough. A small percentage of spam mail may still slip through to your inbox, but it's a rare annoyance and not a constant tidal wave of spam.

There are commercial antispam tools, such as Spam Bully, and SpamButcher, which claim to do an even better job of blocking spam. If you have your own server, SpamAssassin is popular free tool that can be installed at the server level to block spam. It's a little geeky, but highly configurable and very effective.

I have been using gmail for several years and find their spam filters very good. I find the odd good (none spam) e-mail in the spam bucket and move it into my good mail, and dump the rest.

I have several email accounts. I have Gmail download them all for me thus consolidating all my accounts into one download and it's easy as I only have to check one web mail account when I'm at a public PC. And as for spam: Gmail filters out all those accounts for me this way.

Spam Assassin link is not working above. I have that on the server level and even though I asked it to discard email that is is still in my inbox...just marked. Makes for easy deleting, but not what I wanted.

The best spam program (for a email program) is POPFile. Plus it is free.

I am currently a paid member of SPAMCOP.NET. It has an excellent Realtime Blocking List (RBL). It is extremely agressive, but with the use of a 'safelist' it can be tailored.

You also have the option of reporting SPAM, which helps both the effectiveness of the list, and to shut down spammers!

KnujOn ( is a great way to shut down spammers. You simply forward all your spam to KnujOn and they take care of the rest. If you use Gmail, make sure you look at GKnujOn ( which completely automates the process of forwarding your Gmail spam to KnujOn.
