E-Mail
Spoofing
Have
you ever received a bounce-back e-mail
about a message you sent that could
not be received by the recipient,
but you never sent that e-mail out?
This is called E-Mail Spoofing.
What usually happens is you send a
normal e-mail to a customer and their
system has a worm or virus, not yours.
Then their worm or virus looks into
their address book and sends out junk
mail to everyone in their list and
assigns your e-mail address and even
ones from your domain that do not
exist. The recipient may have a sophisticated
e-mail program that detects the problem
and bounces the message back to you.
So with this scenario, changing your
e-mail address will do nothing because
the worm or virus will just use your
new address.
As another note, since we have installed
our Spam Filter, we see an average
of 10,000 messages going through the
system every day and only about 1,000
are valid. The system rejects 9,000
messages per day. Per recommendations
from the manufacturer, we do not have
the bounce back message turned on
as it would create a large amount
of traffic and send messages to people
who have had the same thing happen
as you did. We just reject the junk
and it eventually stops from that
source.
