Spam Filtering

What is Spam Filtering?

MailWall scans all inbound email for Spam like characteristics. The technology used for Spam filtering falls into two classes, connection based and message based.

Connection (pre-acceptance) based filtering analyses the source of inbound email and blocks connections from Spam software and known previous sources of Spam. This filtering also protects against Denial of Service (DoS) attacks. Pre-acceptance filtering is permanently enabled on all MailWall domains and is not configurable.

Message based filtering analyses how emails are constructed for signs that they are Spam. This filtering can be fine tuned (or disabled) on a per domain and per user basis.

Spam filtering is enabled by default.
