CipherTrust's lastest version of the IronMail secure
e-mail gateway contains a "genetic" algorithm for spotting
unsolicited commercial e-mail, or spam, which will adapt to changes
in spam e-mail content.
IronMail 4.0 should reduce the need for customers to modify the
product's settings to increase accuracy or decrease the number of
false positives, and is one of a handful of new anti-spam tools
added to the IronMail product, CipherTrust said.
The genetic algorithm analyses incoming spam e-mail for 900
different message characteristics, detecting subtle changes in
message content and format.
Based on trends that turn up in the spam message flow, the
algorithm then automatically changes the way the IronMail
correlation engine, named the Enterprise Spam Profiler, weighs
those characteristics so as to best stop spam and permit valid
e-mail correspondence.
In addition to the algorithm, IronMail 4.0 adds latest security
features such as URL filtering and domain blacklists to its list of
tools. The product now has 12 different anti-spam technologies.
URL filtering and domain blacklist features, which scan e-mail
messages for forbidden URLs or web domains, can be used to stop
inbound spam and also to create security policies that are applied
to outgoing e-mail, according to Paul Judge, chief technology
officer at CipherTrust.
The IronMail 4.0 also allows organisations to assign anti-spam
rules by network user, group or network domain.
