SPAM
Filtering/Blocking System
MRM Hosting
is pleased to offer all Web Hosting and Email Hosting
customers state-of-the-art Spam/Virus removal software.
We offer complete SPAM protection using three
different antiSpam systems (Internal MailGuard™ logic
system, SpamAssassin™, and user definable rules-based
spam filtering). The use of these various systems is
designed to help you eliminate and remove up-to 98% of
junk mail and viruses from your inbox.
How does it work?
Our Spam Filter solution works to minimise the damage
spam does to your business. The spam filter system scans
every email sent to your account verifying the
legitimacy of the email and determining the likelihood
of the email containing spam. The system is deployed and
administered on the mail server and managed by us
ensuring there is no administrative overhead for your
organisation. The anti spam application works to
identify spam emails before they reach your email box.
Emails are scanned using our internal spam detection and
filtering network and SpamAssassin™ a server based mail
filtering system. Furthermore, an additional layer of
Spam protection can be utilized from enabling the custom
spam filters available from your control panel. This
multi-pronged approach ensures maximum efficiency in
reducing spam to your email box and can reduce spam
levels by up-to 98%. Depending on your specific
requirements the spam filter can manage email identified
as spam in one of two ways:
-
Automatic Deletion
Once a particular email has been identified as spam
it can automatically be deleted ensuring your staff
are never inconvenienced by spam in the workplace.
The emails are erased by the mail server and are
never delivered to the end user dramatically
reducing the presence of spam in your mail box.
-
Automatic Tagging and Filtering
The filtering application can be set to
automatically tag suspected spam emails, once tagged
the email will be delivered to the end user where
the Email Programme (such as Microsoft Outlook or
Outlook Express) will identify the tag and move the
email to your junk folder. In this way emails are
never lost but are simply relocated to the users
junk folder. The user is then able to browse through
the folder on a daily or weekly basis retrieving any
emails that maybe of interest or use.
Benefits of Spam Filter

-
Real-time detection and identification of suspected
emails,

Scalability - from 1 to thousands of mailboxes!
The spam-identification tactics used include:
-
header analysis: spammers use a
number of tricks to mask their identities, fool you
into thinking they've sent a valid mail, or fool you
into thinking you must have subscribed at some
stage. Our Spam filters tries to spot these.
-
text analysis: again, spam mails
often have a characteristic style (to put it
politely), and some characteristic disclaimers and
CYA text. Our Spam filters can spot these, too.
-
blacklists: SpamAssassin™ supports
many useful existing blacklists, such as
mail-abuse.org,
ordb.org or others.
-
Razor:
Vipul's Razor is a collaborative spam-tracking
database, which works by taking a signature of spam
messages. Since spam typically operates by sending
an identical message to hundreds of people, Razor
short-circuits this by allowing the first person to
receive a spam to add it to the database -- at which
point everyone else will automatically block it.
SpamAssassin™ requires very little configuration; you do
not need to continually update it with details of your
mail accounts, mailing list memberships, etc. It
accomplishes filtering without this knowledge, as much
as possible. |
