SPAM FILTERING HOW IT WORKS

Spam & Virus Filtering - How it works 

Getting Started 

The Domain Spam Filter works outstandingly easy:

1. Add your domains to the filtercluster
2. Switch the MX-records of your domains
3. Simply Spam Free!

If you already have added your domains and want to activate the filtering MX-records, please enter the following hostnames in the DNS settings of your domains:

'asf-mx10.mojomonster.com.' (priority 10)
'asf-mx20.mojomonster.com.' (priority 20)

Adminstration & Settings

Administration and settings adjustment for your filtered domains can be done through the user friendly control panel . Domain admins will get access to an overview of all domains and can check on each domain what filtering activities are taking place, which messages got temporarily rejected, which ones were permanently blocked and download raw-logs, set up whitelists, blacklists and the like. Individual users can also log in to their own quarantine and log-search if that is activated through the domain-admin. No good mail can ever get lost!

Learning Mechanisms: Global & per domain IMAP training
  Worldwide user synchronization
Control Mechanisms: - On demand reports with statistics & quarantine release options
  - Domain and user-based online quarantine
  - Raw-log download
  - Online log-search options
  - IMAP based training system
Attachment Blocking: Supported, flexible per extension

User-Locking: Supported (automatic/manual)
Custom Ports: Supported

Installation Requirements

There are no installation requirements. All you need to do in order to activate this hosted spam filter is to add your domain to our cluster and switch its MX-records.

 

Filtering Technologies

Our technology combines both public and internal anti-spam data sources to provide optimal filtering. Thanks to the extensive data processing and gathering, we can keep costs at their lowest for our customers, while sustaining optimal quality of filtering.

The Domain Spam Filter filters e-mail for spam, viruses and all types of malware. It applies more than 50 different technologies. With central databases fed by more than 1 million filtered domains, clients from over 100 countries and countless Desktop users, the latest spam intelligence will always protect your filters.

The filtering itself takes place in two steps: first, the behavior and reputation of the sending mailserver is analyzed which already leads to a 95% detection rate. If an analyzed message passes the first stage, the filters will take a digital fingerprint of the content of the message in stage two and compare it with millions of known spam patterns. After all filtering mechanisms have been applied, a total spam probability is calculated. Below you can find some of the actual technologies the filter utilizes:

Behavioural Checks - Server Analysis

  • Progressive Ratelimiting
  • BATV
  • IP-Analysis
  • SMTP Conversation Verification
  • FROM Restrictions
  • Sender Validity
  • DNS-Records Validity (MX, A)
  • Force Domain Usage
  • SPF
  • Sender Verification
  • E-Mail Flooding Protection
  • Dictionary/Harvesting Attack Detection
  • DDos Attack Protection
  • Botnet Spam Alarm
  • DNS-Based Blacklisting
  • Manual Blacklisting
  • Manual and Automatic Whitelisting

Content Checks - Email Scanning

  • Fingerprint/Hash Detection
  • Anti-Virus
  • Email Size
  • OCR Analysis
  • Statistical Filtering
  • Dynamic Content Analysis
  • Image Conversion
  • PDF & Office Conversion
  • Attachment Analysis
  • Anti-Spyware
  • Anti-Phishing
  • Anti-Virus
