An introduction to spam
4/20/04 - By Frederick Hunter, CEO,

The term "spam" has become a common part of our vocabulary. What started
as humorous slang now describes one of the largest problems
facing all users of Internet email. Spam, otherwise known as unsolicited
commercial
email (UCE) is email sent en-masse
as advertising for a product or service. In a nutshell,
spam is junk mail for your email inbox. As much as paper
junk mail is annoying, so is spam, but with some nasty side effects. Spam,
especially
in large volumes, can keep a user from seeing legitimate
email messages. Spam makes users take time to sift through a mountain
of
email messages just to find the one or two that are legitimate
business or personal emails.
Spam exists because it is cheap to send, and even with low response
rates, very profitable to those who choose to engage in the practice
of spamming. Statistically, if you send out 500,000 emails
and can get %0.01 to respond positively, that is 50 customers. If you
make only $50 per customer that is $2500. Repeat that process once a
week and you have yourself a nice income. Most spammers send many more
than 500,000 messages at a time, and their
response rates can be fairly high, making this a very profitable
business for those who choose to do it.
Statistics vary, but in general the average business email user can
expect to receive 15-20 spam messages per day. Users
whose email addresses are more public can see in excess
of 100 spam messages per day. Each
of those messages must be processed by
the email server, stored for the user, retrieved over the
network by the user, scanned by the user and finally
deleted. The costs in both system resources and lost
user productivity are
staggering. So end users, system administrators and ISP's
are all on a quest to eliminate as much spam as possible
from their networks and
desktops through the use of automated technologies.
The point is clear: it is profitable to send spam, and it is predicted the practice will grow by leaps and bounds over the next few years. It therefore
is a necessity that network operators take steps to stem the tide of spam flowing into their networks. By stopping the flow of spam network administrators can
regain user productivity and save thousands of dollars each year in network operating costs.
