Administrator In Control

Most eMail systems are "black-boxes" with no real-time controls. Merak is vastly better with real time statistics, graphs for several portions of the anti-spam engine and various user and system level alert options. Thus, administrators can reactively engage as needed to highten detection rates and black and white list specific senders or types of events. Detailed reporting and logging is useful after installation to tune the Anti-Spam engine to best performance, without the need for further maintenance.


Quarantine controls integrated in Administration GUI Quarantine can be accessed and managed from remote using Administration GUI, WebAdmin or WebMail Quarantine controls.

Quarantine Management

Users want spam out of their inbox! Merak supports a centrally managed quarantine for each user or for whole domains which is useful to prevent false positives after Anti-Spam deployment. Administrator can inspect the quarantined messages and authorize senders from within Administration interface.
Semi-automatic Quarantine management using Challenge Response can be deployed to build whitelists and then turned off. Why buy $1200-$2000 anti-spam appliances that merely do the same thing but don't give the user a easy to access folder view of their qurantine?

  • Administrator can manage a global Quarantine for all users
  • Domain Administrator can manage Quarantine for whole domain
  • Spam Queue Manager in Administration GUI or WebAdmin: sort, filter, view, control
  • Mutliple actions: Whitelist/Blacklist/Deliver/Delete
  • Semi-automatic management through Challenge Response

SPAM Scoring System

Merak's Anti-Spam module is based on scoring each message. This means that every Anti-Spam method and each option impacts the message score and ups the total message score; and at the end this score is compared with adjustable thresholds. According to this resulting (total) score the message can be marked as spam, quarantined, moved to IMAP spam folder, deleted or a text can be added to its subject. The treshold values are freely adjustable.

  • Settings templates with 3 predefined detection levels
  • Required score adjustable by slider settings
  • Multiple spam actions: reject, delete, quarantine, tag, sort

Powerful Reporting

Reports can be written as X-Headers, attached to the original message or included as Content Analysis to body, so you can immediately see which filters were applied on it within e-mail client. You can define own filters along with a description and fully customize what will appear in the report. Other than that, there are two levels of Anti-Spam logging. This is all of great importantance for tuning of the Anti-Spam settings.

  • X-Header or attachment reports
  • Tests, score, filter results with human readable reasons
  • Two-level logging
  • SpamAssassin rule global hits statistics

Domain Level Spam Administrator

Specific users can be delegated as special administrator(s) who will have access to users' Spam (and only Spam) folders. He can look through the spam for false positives (genuine messages marked as spam) and move them back to the user's Inbox.

  • Access restricted to listed users' Spam folders
  • Can access all domain's users Spam folders
  • Possibility to whitelist senders
  • Can be fully replaced by Quarantine management
