Business Class Email
It is estimated that over 95% of all email traffic is spam, and 2% are viruses.
Spam is not only a distraction; it can serve as a vector for viruses, malware, and
phishing attacks. The proliferation of spam has led to millions of euros in lost
productivity and additional infrastructure costs for businesses and service providers.
Businesses that use standard shared email servers are fighting a losing battle against
spam because spammer tactics are constantly evolving. To defeat spam, the defensive
technology and techniques must stay one step ahead of the rapidly changing threat.
Multi-layered Email Spam Filter
Business class email spam filtering systems are continuously updated, multi-layered
processes that eliminates 98% of all spam with near zero false positives.
Layer 1: The Gateway Scan
As soon as an email arrives, the sending IP address is compared to an aggregated
spam blacklist compiled from multiple spammer tracking systems. The gateway servers
also analyze the email message in the context of other arriving mail. If a large
number of emails are coming simultaneously from a single IP or are addressed to
random addresses that do not exist in the system, it could signify a spam attack
and the email will be blocked. If the sending address is from a domain in the system
but the mailbox does not exist, the email will be blocked. This last case is called
"spoofing" and it is the reason you may have received spam from your own
email address or domain.
Layer 2: Cloudmark Scan
All email is scanned by Cloudmark's industry leading spam detection software. Cloudmark
uses Advanced Message Fingerprinting™ to detect spam, phishing, and viruses.
Instead of relying on a spam blacklist, Advanced Message Fingerprinting examines
algorithm patterns that expose spam across all languages and character formats.
These patterns are updated every 60 seconds based on worldwide feedback loops and
the latest spammer tactics.
Layer 3: The Message Sniffer Scan
Email is then scanned with Message Sniffer from ARM Research Labs. Message Sniffer
relies on pattern recognition and machine learning technology to detect spam and
malware. It searches the entire message for spam, virus, and malware features including
unusual headers, structural artifacts, message source behaviors, obfuscation techniques,
email and URL targets, binary and image signatures, unusual code fragments, and
even coding styles.
