Spam mutates at an ever-increasing rate, and the volume
of spam is already more than the volume of legitimate
e-mail. Unsolicited commercial e-mail, or spam, is a productivity-sapping,
resource-draining threat to business collaboration. To
combat the increasingly sophisticated techniques employed
by spammers, organizations need to fight spam with a multi-layered
approach that combines a broad range of techniques to
turn spam’s own objectives, characteristics, and
defenses against itself.
Ipswitch Collaboration Suite stops spam
and reduces false positives with a range of different
strategies, such as:
powered by Mail-Filters
Using a unique approach combining machine and human
intelligence, ICS Premium Anti-Spam stops spam and virtually
eliminates false positives with a single click. ICS Premium Anti-Spam is available with the Premium and ISP/EDU Editions only.
Sender Policy Framework
(SPF) to combat Phishing attacks
Sender Policy Framework is an extension to the DNS system
that enables stronger authentication of the source of
a message. ICS now supports SPF to reduce the incidence
of “Phishing” attacks where spam messages
pose as legitimate correspondence to trick users into
giving up passwords and personal information.
Blackhole Lists (RBLs)
These lists use third-party services that include domain
names and IP addresses of known spammers to block spam.
This technology enables ICS to defeat attempts by spammers
to use HTML formatting tricks to bypass simple content
filters. It removes HTML tags and comments prior to
the statistical analysis of the words in the message,
and detects a wide range of other formatting tactics
including broken MIME headers.
Over time, these filters “learn” to separate
spam from legitimate mail by continuously analyzing
incoming messages and identifying the phrases and attributes
that characterize spam.
Kill lists enable you to block spam coming from specific
domains or email addresses.
IP Addresses and White Lists
These lists of trusted e-mail addresses or IP addresses
minimize false positives.

These techniques are applied at multiple levels including
connection filtering, SMTP filtering, content filtering
and delivery rules. In addition to blocking e-mail spam,
ICS puts a stop to annoying instant messaging spam too,
because the IM namespace and user list is completely under
