MailEnable Enterprise Guide
Message Filtering Overview

MailEnable has two types of filters; global message filters and mailbox message filters.

  1. Global message filters are processed by the MTA service andapply to all sent and received mail passing through the mail server. Global message filters are configurable by Administrators under the MailEnable Messaging Manager. 
  2. Mailbox message filters are processed by the post office connector service andapply to a message before it is delivered to a mailbox. These filters have a more limited selection of criteria and actions that can be applied. Mailbox filters can be configured in the administration program, or users can configure their own mailbox filters via web mail.
