- 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.
