Spam continues to be the most significant challenge facing email
administrators today. Enterprise administrators consistently report
levels of spam that well exceed half of the incoming email and in
some cases approaching nearly 90% of all incoming email. Legal
actions have proven difficult if not impossible to enforce and
little progress has been made in reducing the amount of spam in the
Internet today. While there does not seem to be any effective legal
or other solution forthcoming, it is possible to manage the level of
spam activity by implementing effective software and hardware
filters that will identify and block spam before it enters the
The most effective products are those that use a variety of
techniques to identify and block spam; most enterprise class
products today use a combination of reputation services such as
various Real Time Black lists and country specific IP address
blocking. A variety of other techniques are employed, the most
effective of which employ zero-day protection frameworks.
In addition to spam blocking, there is an increase in demand for
content filtering to help achieve a number of compliance
requirements both inbound and outbound. Lastly, email continues to
be a primary vehicle for transporting other types of network malware
threats such as viruses and spyware.
The most effective products will include a spam component, a
content filtering component to help achieve compliance and a
security component to identify and neutralize threats such as
viruses, malware, spyware and other email borne threats.
