This is a Tutorial on How Get Rid of Spam
Once and For All. This guide will help you avoid getting
hundreds or thousands of junk emails (spam, UBE, unwanted commercial
emails) that occur naturally when you open a web site. I’ll
explain why it happens, how spammers find you and some tricks of
the trade that I’ve learned over the years to foil their plans
to barrage you with unwanted commercial advertisements for every
real estate, prescription and scam known to mankind. There are some
techniques that are easy to implement and others that require a
bit of extra effort, often the return is worth the effort. As the
author of a widely used spam blocking program called SpamVault,
I know about spammers and their tricks.
The Easiest Way to Avoid Getting Spammed
One of the best tools to taking control of your
destiny is your own domain name. Not only do you then get your own
web site but you also get some special tools to use to avoid spam.
Simply put the easiest way to avoid spam is to take a pro-active
approach from day one to prevent spammers from getting your email
address. Typically after setting up your domain name, even without
a web site, you can start setting up email addresses. I recommend
that you start with four email addresses. This may seem excessive
at first but when you understand the logic in this you will never
do it any other way.
- Junk Email Address: This address is the one
you put out in the public on you web site, the one you use to
sign up for newsletters, the one you give to any organization
that hasn’t proven that they are not going to be sending
you unwanted emails or selling your address to others. This will
be a very busy email box that people will use until they fall
into one of two categories; 1) Business 2) personal. For this
address I recommend using a name like, email001@yourdomain.com.
This way, if it gets abused, you simply turn it off and change
it to email002@yourdomain.com.
- Business Email Address: This is the email address
you put on your business cards. It should be something easy to
remember but not exactly something personal. You would only provide
this email address to “individuals” who you know through
business. When you do get an individual’s email address,
they then can have your Business Email Address as well. If you
just struck up a relationship with an online advertising agency
who is going to provide your company with a service but don’t
know the individual who you’ll be working with, give them
the Junk Email Address for now.
- Personal Email Address: This one is by far
the most private email address. It’s for friends and family.
You’ll probably find that this is also the most important
email address and therefore keep it private.
- Wildcard Email Address: The COMPANY_NAME email
system allows you to have one address called a ‘default’
address which catches any email sent to your domain that doesn’t
have a formal box set up. The default address then forwards your
email to the box of your choice. I recommend you forward any mis-addressed
email to your Junk Email Address. Using the address wisely is
a great way to figure out who is reselling your email address.
When I shop on line, I never want to give the store or service
my Business or Personal addresses. Even if the purchase is for
business. Instead I give them an address named after their domain
name. For example, if I’m buying something from widgets.com,
I’ll tell them that my email address is widgets.com@mydomain.com.
Then when they send me a confirmation or any further correspondences
it will be directed to my junk mail box by the ‘default’
address. The key here is that if I start getting email sent to
this custom created email address from somewhere other than widgets.com
I’ll know who is selling my email address and then I can
block that address forever more. Note that from day one, spammers
who get a hold of your domain name may/will start sending you
email to addresses that are not your own in hopes that you are
using a wildcard email address. They don’t care if it’s
your junk email box, or if you never read it, their job is to
deliver spam. Any time email doesn’t get rejected, they
get paid.
Obfuscating (encode) Your Email Address
The next challenge is to make it difficult for
spammers to get your email address while making it easy for clients
who need to get a hold of you. To understand how to do this you
need to understand a little about how spammers get your email address
in the first place. Spammers use “spambots”
or programs that troll the internet searching for email addresses
to build huge databases of email addresses. They then offer the
service of mass mailing to unwary or unscrupulous merchants who
wish to help you part with some of your hard earned cash.
Our goal here is to trick the spambots.
How? By encoding (known to propeller heads as "obfuscating")
the email addresses that we put on our web site in such a way that
a spambot won’t recognize it. Here are some good techniques:
- Obfuscation. Here’s
a link to a little program that will encode your email address
in such a way that 90% of the spambots will not recognize but
100% of browsers and humans will. This is my number one recommendation
for avoiding spam. Still, it’s best to use your Junk email
address discussed above even though you can be pretty well assured
of avoiding spammers using this technique.
- Whenever you post your email address in newsgroups or other
public places where spambots can find/will find them, add some
spaces in the address so that people can see the address but spambots
will probably get it wrong or won’t recognize at all. Example:
myemail @ mydomain.com. Note the spaces around the “@”
symbol. Again, always use your junk address in public places.
But What If I'm Already Getting Spam?
Following the suggestions above will help you
avoid 99% of spam if you’re domain name is
new. And for those of us who receive hundreds of thousands of spams
per month, it is worth the effort, but what about those who are
already getting spammed to death. Don’t worry there’s
hope.
Avoiding spam once your email address is out
there is a bit more challenging. In some cases the email box you’ve
known and loved is beyond hope. It might be better to simply block
that address and start using a new one. Before this happens, why
not try the following techniques.
Use SpamVault to block Spam
AceOfSpace.com offers
a great program for blocking spam called SpamVault. I originally
wrote SpamVault as a little project to help curb my own spam problem.
I run a small association for hosting companies (my competition)
and I soon discovered that I was not alone in getting a lot of junk
mail. In fact, others were getting deluged with junk mail far worse
than I was. Over the years I’ve developed SpamVault for my
clients and then I began providing copies of SpamVault to other
hosts to help them and their clients block spam. Now my little project
has taken on a life of its own and is available to over a 1,000,000
users world wide and has blocked untold millions of unwanted junk
mails and viruses.
SpamVault will block email based on several criteria
within the email including where it came from, what is in the subject
or body, what’s attached to the email, and even does pattern
matching to foil many of the tricks played by spammers to bypass
filtering software such as SpamVault. One of the strongest features
in SpamVault is it’s white list capabilities where you can
make a list of friends who can write to you, and everyone else is
blocked.
On of the advantages of SpamVault over programs
that work on your computer is that since SpamVault works at the
server level, the email is vaporized before you download it. This
will save you time and money because you don’t have to wait
for junk emails to be downloaded, you in turn don’t have to
read the junk emails, and your data transfer usage is reduced.
For clients hosted at AceOfSpace.com,
you have the advantage of using the latest version of SpamVault
to block junk mail.
Here's a resource that will teach you more about
where the spam is coming from.
By viewing the header of an email you can learn a lot about it's
source.
Bayesian Email Filters
A newer technique for blocking spam is to use
a program that ‘learns’ what is and what is not spam
based on your own opinions. These programs use a special algorithm
called Bayes'
Theorem. Many people swear by these programs, however, the results
I’ve seen are similar to filtering programs like SpamVault.
More important than comparing the programs, I suggest using every
tool at your disposal to create a spam blocking arsenal.
Do We Still Get Spam?
Sure, we're not immune. I run a web hosting
company like AceOfSpace.com
that is constantly putting its domain and email addresses on line
for the world to see. In fact, I have several email addresses that
are spam-magnets which I use to test SpamVault. However, I have
many email addresses that never get any spam at all. Those that
do get spam are those that have been around long before I started
learning the techniques I’m sharing with you here.
Start Avoiding and Blocking Spam Today
If you start using these techniques today,
I promise that you can avoid 95% to 99.9% of spam in the near future.
I wish you well.
Added Value of AceOfSpace.com
In addition to these suggestions, AceOfSpace.com
provides a three-pronged approach to blocking spam on all of our
servers
1- We provide each account with SpamVault a program
designed to filter email. This $60 value is free with every account.
2- We utilize serverwide spam blocking for the
most obvious spams such as emails with "viagra" in the
subject line.
3- We subscribe to several internet watchdog groups
that provide access to their database of known spammers and exploited
computers.
4- We are always looking for new ways to block
spam. Our most recent addition is the use of special black lists
of spammers.
