Spam detection is performed by the Anti-spam component which analyses the contents of e-mail messages and defines whether it is spam or not according to the spam-rate value summed up from various criteria (the spam message is also related to a certain category according to how likely it is that the message contains spam: Certainly spam, Probably spam or Unlikely spam). For each category you can specify a certain action (see below for description of Anti-spam settings).
The Anti-spam component is available only with the “Anti-virus + Anti-spam” version of Dr.Web for IBM Lotus Domino. If your key file supports the Anti-spam component then spam detection should be enabled by default.

If all the settings in the Anti-spam frame are disabled then it is likely that your license key file does not support the Anti-spam component (see License Key File). To check this, you can open the key file (/local/notesdata/drweb32.key) with a text editor and look for the following string: LotusSpamFilter=No. |
To set up the Anti-spam for a profile:
| 1. | Make sure that your version of the program includes the Anti-spam component. |
| 2. | Choose the necessary profile in the hierarchical menu and click the Anti-spam item. |
| 3. | By default, the Anti-spam component is enabled. If it is not, you can enable the component by selecting the Enable check box. |
| 4. | If you want a prefix to be added to the subject fields of spam messages, select the Change subject check box. You can edit the prefix itself in the Subject prefix entry field (by default, it is set to [SPAM]). |
| 5. | Besides adding a prefix to the subject of spam messages, you can select actions for various categories: |
| • | Move to database for spam - means that the spam message will be moved to the database specified in the Database for spam text box (if the specified database is not found, the spam message will be passed on to the receiver). You can also specify a certain folder inside the database in the Folder text box and the spam message will be moved to this folder (if this folder is not found in the database, the spam message will still be moved to the database but not inside a folder). |
| • | Reject message - means that the spam message will be received by the server and deleted without passing it on to the receiver. However, a document for this incident will be created in the Quarantine.nsf database. |
| • | None - means that no action will be applied to the message and it will be passed on to the receiver (the subject will still be changed if the Change subject check box is selected for this category). |
|
To keep spam-messages, use any of the Notes databases, based on the standard postal template, for example, Mail7.ntf. Besides, DrWebSpam.nsf database is supplied with Dr.Web plug-in. DrWebSpam.nsf is installed in the Drweb subfolder of the Lotus Domino server data folder. This database is based on the template, similar to quarantine and incidents database, and it provides some extra functions, which can be useful for spam processing: several types of filters, blocking from removal, automatic removal of old messages, delivery of the messages, that were wrongly classified as spam, to user. It also allows to add senders to white or black list. |
| 6. | When you finish adjusting the Anti-spam component, click Save. |

If the spam filter regards certain messages as spam by mistake, you are advised to forward such messages to special e-mail addresses for analysis. Messages which are wrongly regarded as spam should be forwarded to vrnonspam@drweb.com, and unblocked spam messages should be forwarded to vrspam@drweb.com. Forward messages as attachments; do not include them to the message body. |
