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. |

[edit] Configuration
[edit] 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
[edit] Subject Tag
Select the subject tag used to mark any messaged deemed to be spam.
