101
Are you
tired of getting spam? We all are, in fact there is a
booming business on fighting spam such as spambully.com. They
filter out mail that comes to you, forward mail to your
phone. Their program lets you create a white list of
people who can send you mail. You can create challenge
emails so that people send you mail can verify that they
are human and then you receive the mail. This integrates
with Outlook and Outlook Express and can help alleviate
some of the headache you space from spam.
What is Spam?
Spam by
definition is "unsolicited email". That means any mail
you did not request or from someone you don't know. If
you sign up for a newsletter and they send you mail then
that would be called an opt-in list, meaning you gave
them permission to send you newsletters and other types
of email, and the would need to provide a link for you
to "opt-out" at any time from their newsletter or email
system.
Point System
Spam
Spam works on a Point System, for
instance a person sends out 5,000 emails with the same
subject, and content this email would receive a high
Spam Point by whatever spam blocking
agent is located on the mail server such as spamassassin.apache.org
Spam assassin can be set to take all spam and send you a
message about it or put it into a default mailbox
typically referred to as the "black hole". If the same
guy sends out one message at a time changing each
message in a different way then these emails would be
assigned a low Spam Point and most
likely get through. Now is this message was sent to
multiple accounts on the same mail server it would
generate a higher Spam Point and most
likely be blocked as Spam.
Mail Spoofing
Have you
received email stating "Sorry but i could not deliver
your message to the mailbox", but can never remember
sending such email at all and upon looking at the email
noticed that it was spam but you never sent it ? This is
called E-Mail spoofing. It means someone sent email and
made it look like it came from you. You would have never
known about it unless someone sent you an email saying
stop sending me spam. The message above is called an NDR
a "non deliverable report" meaning that the email
address to send the mail to could not receive the email
for one reason or another.
