How Cloudmark Server Edition works

CSE communicates with the Microsoft Exchange Server through the Microsoft Messaging Application Programming Interface (MAPI) to receive notifications when messages arrive and to perform various pre-concerted actions on messages that are determined to be spam.

How Cloudmark Server Edition Works
  1. Email arrives at the Exchange Server.
  2. CSE computes a unique fingerprint — which does not contain message content and cannot be decoded — for each message.
  3. CSE sends the fingerprints to the Cloudmark Global Threat Network for evaluation.
  4. The Cloudmark Global Threat Network sends a response to the CSE server indicating whether the message is spam or legitimate.
  5. Depending on how you've configured CSE, it either tags the message as spam, moves it to a designated spam folder, or deletes it.

Cloudmark Server Edition does not block the regular flow of messages, so its operation has no impact on throughput.
