Modules - Antispam - Quarantine

Overview

The Dspam antispam system tracks e-mail by mailbox. In other words, the antispam system bases its decisions on individual spam databases for each user on the system.

Installation

If you did not select this module to be included during the installation process, you must first install the module.

	Warning!

Since the Dspam antispam solution requires specific details about mailboxes and aliases, the software is not available on systems configured as a mail gateway. For example, a message destined to sales@example.com forwarded to an Exchange server may end up in Mary and David's mailbox. It is not possible for the Dspam system to determine this information in mail gateway mode.

Configuration

Signature Location

The antispam system tracks important elements and statistics on every e-mail message that you receive. This information is then stored as a "signature" -- basically a unique identification number. To train the antispam system (see next section), this signature must be included in an e-mail. You can track these signatures either in the body of the message, or in the message header.

Headers

• advantage: does not clutter the body of e-mail messages
• disadvantage: message must be forwarded as an attachment to train the antispam system

Body

• advantage: message can be forwarded (no attachment) to train the antispam system
• disadvantage: spam signature clutters the body of e-mail messages

Subject Tag

Select the subject tag used to mark any messaged deemed to be spam.
