Legitimate Emails Fall Prey To Spam Filters
Spammers Advancing Techniques Blurring The Line Between What's Real And What's Spam
CEDAR RAPIDS, IA - March 3, 2004 /Send2Press Newswire/ -- Spammers continue to improve their ability to
deceive the readers by changing the format of their spam. Spam filters attempt to automate the task of
separating spam from email by looking at key words, phrases and other key characteristics of spam. As
spam more closely resembles real emails of interest from friends or co-workers, filtering systems will
eventually have to block more legitimate emails or let more spam through. Such filtering problems are
not an issue with Mail Unknown Anti-Spam software (www.mailunknown.com) from Matrix Productions, Inc.
"Filtering and global block lists were just a few methods discussed when we began development of our
Mail Unknown Anti-spam software in mid 2001. They were quickly thrown out because they posed a high risk
of mistaking valid emails for spam, better known today as a false positive," says Matrix Productions,
Inc. President Dennis Turkington. "Now, almost a year and a half later, we know we made the right
choice. We see an increasing number of people posting in forums, news groups and even reporting directly
to us that they fear using spam filtering applications because of false positives."
Mail Unknown first verifies that the senders email address is real. Fake addresses are blocked
immediately. Real addresses are sent an Authorization Request email. All the sender is required to do
is reply to the request. Once Mail Unknown receives this reply the user is prompted to authorize or
block that sender. This Verify then Validate technology gives Mail Unknown users full control. Mail
Unknown users can look through the emails currently blocked or pending inside Mail Unknown if they think
they have missed an email. This method achieves fewer false positives, less undetected spam and full
control by the user.
"Although Spam filters continue to improve, only a 'verify and validate' method will continue to work
effectively as spammers step up their attack," concludes Turkington. "Inevitably spammers will find
ways around filters and more filters will mark valid emails as spam."
