Spam
(unsolicited commercial e-mail) accounts for 35% of all
messages and is rapidly increasing. 1 in 150 messages
contains a virus, costing many billions of dollars around
the world every year.
At
JKAhosting, we take this very seriously. Therefore
we use the latest AntiVirus and AntiSpam filters on our
servers.
Every
web hosting account comes with complete SPAM protection
using three different antiSpam systems
(Mailscanner™, 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.
Each email is checked by this filtering service which
determines if the email is from a known spam source and if
it contains any known viruses. The service gets
information from many spam detecting and filtering
networks so it can perform reliably. We catch around 95%
of all incoming spam and over 98% of all viruses.
 How
does it work?
Our
Spam Filter solution works to minimize 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 organization. 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
- Fully
managed spam prevention system, minimising
administrative overhead for your organisation,
- Constant
checks for consistent spammers against an independent
database of identified spammers,
- Scans
email at the mail server, therefore emails identified
as spam need never reach your desktop,
- 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.
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.
