Implementing the best email filter for Microsoft Exchange is the ideal way to eliminate the unwanted spam still allowed through by Microsoft´s product - even with “Exchange Online Protection” (EOP). A supplementary exchange email filter can provide better protection against email-borne threats and ensures email continuity throughout the network during downtime.

How the Microsoft Exchange Email Filter Works

The Microsoft Exchange email filter - like most other email filters - uses multi-layered mechanisms to rate each incoming email and assign it a spam confidence level. Incoming emails are compared to a blacklist of known spam sources and analyzed for compliance with sender policy frameworks.

Any incoming email that exceeds a preset spam confidence level is flagged and either quarantined, deleted, or forwarded to its recipient tagged as spam. The Exchange email filter reports on all quarantined, deleted or tagged emails, so that those flagged in error can be reinstated and the email sender included on a whitelist.

How the Best Email Filter for Microsoft Exchange Differs

Before illustrating how the best email filter for Microsoft Exchange differs from the default Exchange email filter- or more accurately enhances the default Exchange email filter - it is important to understand some of the issues with Microsoft Exchange and its premium EOP service.

When Exchange 2013 was launched, the premium service replaced Microsoft´s “Forefront Protection for Exchange”. Only supplied as a cloud-hosted service, EOP does not support sandboxing, real-time dynamic link following, and “greylisting” - a mechanism that helps detect previously unknown sources spam.

How the best email filter for Microsoft Exchange differs is that it has a choice of deployment options and the mechanisms needed to deliver in excess of 99% spam detection. Furthermore, whereas Microsoft Exchange and its EOP service has a high maintenance overhead, the best email filter for Microsoft Exchange focuses on usability rather than complex configuration options.

SpamTitan checks every URL in an email against known blacklists - with 100% active web coverage.
