You'll probably be familiar with the twin menaces of email-borne viruses
and unsolicited email, commonly referred to as spam. You'll understand the
annoyance caused by that avalanche of junk email which somehow finds its
way uninvited into your inbox, destroying the efficiency of your email system,
consuming expensive bandwidth and wasting your valuable time.
filters unwanted and harmful email messages out of your inbox on the server.
This means it doesn't get downloaded to your computer, thus saving your
time and money.
It is estimated by that more than half of email messages transmitted on
the Internet today are spam and most analysts predict that this will continue
A Gartner survey in 2002 revealed that staff were already spending an
average of 49 minutes per day (10% of their time) managing their email.
Further, the IT department is increasingly occupied supporting users with
spam issues and dealing with the fallout from virus infections, rather
than working on productive projects.
Downloading unwanted email costs money in telephone and data transfer
charges. The bandwidth consumed means your Internet connection runs slower,
destroying the efficiency of your entire operation as commerce becomes
ever more reliant on Internet applications. European commission figures
put the cost of spam to European businesses in connection charges alone
at £6.4bn per year.
A significant proportion of unsolicited email messages contain pornographic
content causing distress to the recipient and creating dangers for younger
users. Additionally, a number of employees have already successfully sued
their employers for failing to provide adequate protection from pornographic
Fraud & Identify Theft
Emails using social engineering techniques and spoofed web sites to dupe
the reader into disclosing confidential information such as online banking
access details, addresses and credit card numbers are a growing trend.
There is also the infamous Nigerian 419 scam in which a deposed African
dictator offers a cut of millions of dollars for your help transferring
it from a secret account in Africa to yours. People were stung for an
estimated £8.4 million last year in the UK alone through advanced
fee and other forms of online fraud.
The convergence of virus and spam technology means that the problem will
only get worse. Recent virus attacks such as the Sobig and Klez worms
have brought corporate email systems to a halt, clogged inboxes with useless
mails, cost industry billions in clean up costs and have the potential
to inflict terminal damage on today's online businesses.
SPAM Bouncer is a unique product utilising advanced
technology to rid your inbox of irritating spam and harmful viruses. You
no longer have to download and filter junk messages, saving your time
SPAM Bouncer operates server-side. Every email destined for your mailbox
is scanned and checked by a number of different processes at the point
of entry into our network.
Thousands of tests check the message headers and content for tell tale
signs of spam. The originating mail server and sender's address are verified
to prevent spoofing. We proactively monitor and adapt the tests used by
SPAM Bouncer to any new techniques the spammers employ.
Bayesian Probability Algorithms
Bayesian algorithms are used to build up a database of the characteristics
of unwanted mail and the characteristics of legitimate mail. The database
can then be consulted to determine the likelihood of any particular message
being spam. Furthermore, through continually analysing messages the database
is actively updated as the nature of spam changes, creating a form of
self evolving intelligence.
Any message has a unique checksum, as users report unsolicited mail messages,
their checksums are added to a database. Several collaborative checksum
databases are consulted to ascertain whether the message concerned matches
one previously identified as spam by another Internet user.
Real Time Blackhole Lists
Several real time blackhole lists (RBLs) are maintained on the Internet
which catalog known sources of spam. SPAM Bouncer checks for the presence
of the originating mail servers in any of these lists.
All our hosting accounts include virus scanning as standard, a feature
which operates in unison with SPAM Bouncer. Virus definitions are checked
for and updated automatically ensuring that you are protected against
threats as they emerge. The virus scanner is capable of detecting all
known virus types, including polymorphic or self-encrypting viruses, it
is even capable of scanning the contents of compressed archives such as
zip and rar files ensuring that no virus bearing email can make it to
Each positive test assigns a weighted score to the incoming message.
The final score is used to determine whether or not the message is spam.
This scoring system combined with the quantity and diversity of tests
performed means that unlike most competing products, the likelihood of
SPAM Bouncer incorrectly identifying a message as spam is negligible and
makes it nigh on impossible for spammers and virus writers to craft their
messages to bypass the filters.
You have complete control over the handling of any mail identified as
spam. Choose from the following options:
- Reject Return the message to the sender with an informative message
detailing why their message was rejected.
- Tag Add headers or text to the message subject enabling you to filter
all unwanted email into a specified folder using rules in your email
- Quarantine Send it to a mailbox you specify in which you can view
and verify suspect messages or archive them should they be required
in the future.
From the moment you activate SPAM Bouncer on your mailbox you can expect
to see all virus bearing mail and upwards of 98% of unsolicited mail eradicated
from your inbox. However you can tune the sensitivity of SPAM Bouncer
as well as add addresses and domains to your block and allow lists to

We can't guarantee that every spam email will be detected. It will often
be necessary to receive a message and add the address to your SPAM Bouncer
block list to prevent further messages from being delivered. Therefore,
SPAM Bouncer should be used to complement not replace firewall and virus
detection programs that you may be running locally on your computer systems.
We strongly recommend not only installing such products but also wnsuring
that the virus definition files are checked and updated as necessary on
a daily basis.
