LYPHA
is pleased to offer all Web Hosting and Email Hosting customers
state-of-the-art Spam/Virus removal software. Every web hosting
account comes with 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 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.
-
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.
