Primary to the effectiveness of the MX Logic Email Defense Service is our Stacked Classification Framework® spam detection system, which is powered by patented technology and combines the most effective spam-fighting filters and techniques in the industry. :
-
IP Reputation Connection Manager: This filter operates at the front of the Stacked Classification Framework and rates the reputation of every incoming message, based on IP reputation data collected on an on-going basis by MX Logic. Connections are dropped for all messages which originate from IP addresses that are determined to carry a reputation for sending spam.
- Premium Anti-Spam Multi-Language: This filter provides MX Logic with a global view of spam traffic, which enables us to defend against real-time spam attacks and rapidly identify zero-hour spam, regardless of language. The filter is also effective at identifying image-based spam and phishing emails, and is continually updated based on real-time feedback provided by a global network of users.
- Statistical Filtering: MX Logic's probabilistic filtering utilizes a statistical Bayesian algorithm to determine the probability that an email message is spam based on how often elements in that message have appeared in other spam emails.
- Sender Policy Framework (SPF)/Sender ID - For inbound messages, MX Logic can check if the message has an associated SPF/Sender ID record. If there is an SPF/Sender ID record, it can help determine if the email sender’s domain is from a list of IP addresses authorized to send email from that domain.
- Industry Heuristics: MX Logic incorporates thousands of successful industry-wide spam-fighting rules into its filtering layers.
- Proprietary Heuristics: Our experts write and update thousands of proprietary rules to block spam using real-time data from the MX Logic® Threat Center.
- Reputation Analysis: Like allow and deny lists, reputation analysis blocks spam based on comprehensive information about the source of the message - rating the reputation of the sender based upon the percentage of spam messages sent from that IP address in the past.
- URL filtering: URL filtering works by comparing embedded links found in email messages with URLs associated with identified spam.
- Reputation-based RBL filtering: MX Logic assigns a level of trust to key real-time blackhole lists (RBL), which rates the reputation of the RBL based on its accuracy at blocking spam.
Additional filters increase protection
MX Logic employs other filters to ensure that your email is virtually free of spam including the following domain-level allow and deny lists and distributed black lists:
-
Domain-level allow and deny lists: Specifically designed to protect against spam, inappropriate content, and email attacks, domain-level allow and deny lists filter and block unsolicited messages.
-
Distributed black lists: Distributed black lists comprise a number of real-time subscription services including the Mail Abuse Prevention System (MAPS) and MX Logic's own global deny lists, which include multiple lists of known spammers and their IP addresses.
-
Recipient deny lists (Address): This type of filtering is designed specifically to filter for content and relieve network servers from attempting repeatedly to deliver mail to invalid addresses.
-
User-level allow and deny lists: Through regularly-delivered MX Logic Spam Quarantine Reports, end users have the flexibility to develop their own, personal allow and deny lists.
