Anti-Spam issues and Netstar Communications e-mail
If you have an email address, at one point in
time you will receive an unsolicited email also
known as SPAM. And that is not just advertising,
SPAM is used to send viruses, and a new term called
phishing to lure people into websites that look
legitimate but their sole purpose is to steal
SPAM is costly
Security experts say "E-mail is evolving into a hacking tool that
threatens its usefulness for communications and
commerce". An avalanche of junk
e-mail, scams to filch personal information and
sophisticated computer viruses cost more than $15
billion in personal losses and lost workplace
productivity last year, market researchers say.
Our statistics show that only in the last 7 days
(for just one of our servers), there has been over
3.64 million unsolicited email sent to our servers.
Our servers have defeated over 38000 email viruses,
have rejected over 63000 known spammers using
real-time black hole lists and have blocked over
1.85 million spammers attacks trying to steal your email
address from our server.
What is Netstar Communications doing about it?
Numerous Anti-Spam measures have been taken by
Netstar Communications in the past 6 years to stop
this type of email abuse. Our servers employ the
latest slew of technological prevention systems to
defeat these harmful emails. At this time we employ
Bayesian Filtering, SpamAssassin, Challenge-Response
Mechanism, Spam URI Real-time Block list, White and
Black Lists, Email Content Filtering, HTML Filtering
to name a few. To read about every and each of these
filtering technologies, go to
How do we protect your email
from SPAM. But the
most important one, Challenge-Response, is what we
would like to discuss with you today.
What is Challenge-Response?
The best line of defense is a Challenge-Response
mechanism, the most foolproof spam blocking method
known to block 100% of computer-generated spam. If
the SpamAssassin and Bayesian filters cannot
definitively prove that a message is or is not spam,
a challenge message is sent to the message
originator. The sender is presented with an embedded
link in the message. Once the user clicks on this
link and enters the displayed code, their message
and all of their future messages will be allowed.
This method will only do this once for anyone who is
sending you an email. Once they respond to it you
will be able to continue receiving mail from them
with no further intervention from the mail server.
This method will prevent computer generated mail,
which is usually how millions of spam is generated
daily, from reaching your email box.
What if I receive mail from mailing lists or
computer generated lists that I do want to receive?
A well thought of method, usually keeps all the
angles of a situation in mind, in order to become a
solution. This is no different. In order for you to
see who has sent you what and whether they have been
marked for challenge-response, you have the option
of seeing all the awaiting email using your web
browsers. Simply connect to our web mail system with
your username and password, and then click on
settings. In that page click on challenge-response.
You will see a list of all the pending email. You
can either authorize them yourself, or wait for the
sender do his/her part to become authorized to send

generated email that might be important to you.
What if I don't like this feature?
If you decide you do not want this service, there is
another choice available to you. You can also use
our "spam folder mode". What this does is that any
email recognized by our servers as SPAM, can be
moved into a folder called SPAM under your mailbox
on our server. The only way to review these filtered
email, is to log into the webmail service and review
the folder called "Spam folder". By choosing this
service you will receive only email that is not
marked as SPAM by your regular email client, such as
outlook. All other tagged (SPAM) email is stored on
your webmail. This will probably cut about 80% of
your daily SPAM.
Whichever method you will choose, we hope will help
greatly with your email experience and will
definitely help cutting down on the amount of SPAM
