#### Configuring Spam Filter

To configure the spam filter for a mailbox:

1. On your Home page, click Mail in the Services group.
2. Click the e-mail address you need.
3. Click Spam Filter in the Tools group. Configure the following settings as desired:
   - Use server wide settings. Select this option if your provider or server administrator has prepared black and/or white lists of e-mail addresses that you would like to use together with your own restrictions. Black list, shown under Black list group, includes e-mail addresses of spammers, and White list, shown under White list group, includes e-mail addresses of trustworthy correspondents or entities. If the Use server wide settings check box is grayed out, i.e. not selectable, this means that there are no preconfigured spam filter settings on the server.
   - Hits required for spam. This setting adjusts spam filter sensitivity. SpamAssassin performs a number of different tests on contents and subject line of each message. As a result, each message scores a number of points. The higher the number, the more likely a message is spam. For example, a message containing the text string "BUY VIAGRA AT LOW PRICE!!!" in Subject line and message body scores 8.3 points. By default, the filter sensitivity is set so that all messages that score 7 or more points are classified as spam.
   - If you receive lots of spam messages with the current setting, to make filter more sensitive, try setting a lesser value in the Hits required for spam box; for example, 6.
   - If you are missing your e-mails because your spam filter thinks they are junk, try reducing filter sensitivity by setting a higher value in the Hits required for spam box.

     Note: To further improve spam filter accuracy, you may want to train your spam filter on e-mail messages you receive (see the instructions on improving accuracy of spam detection below).

   - What to do with spam mail. If you are sure that your spam filter is accurate, you may want to set the filter to automatically delete all incoming messages recognized as spam. To do this, select the Delete option. If you wish to filter mail with the software on your local computer, select the Mark as spam and store in mailbox option, and then specify how spam filter should mark the messages recognized as spam. "X-Spam-Flag: YES" and "X-Spam-Status: Yes" headers are added to the message source by default, and if you want, the spam filter will also include a specific text string to the beginning of Subject line.
4. To save your changes, click OK.
5. If you do not want to receive e-mail from specific senders, add their e-mail addresses to the spam filter's black list.
   - To add an entry to the black list, under Black list group, type an e-mail address into the E-mail pattern box. For example: address@spammers.net, *@spammers.net. An asterisk (*) means any combination of symbols. Click Add.
   - To remove an entry from the black list, select it and click Remove.
6. If you want to be sure that you will not miss e-mail from specific senders, add their e-mail addresses to the spam filter's white list.
   - To add an entry to the white list, under White list group, type an e-mail address into the E-mail pattern box. For example: address@mycompany.com, *@mycompany.com. An asterisk (*) means any combination of symbols. Click Add.
   - To remove an entry from the black list, select it and click Remove.
7. If you want spam filter to consider some networks to be trusted:
   - Select the Trusted Networks tab.
   - To add an entry to the list, enter a network address into the fields next to Network/Mask and click Add.

     A network is specified by its starting IP address in the first four fields of the Network/Mask field group. The fifth field is for specifying network mask. It should be a number ranging from 1 to 32, which shows how many higher bits set to '1' the mask contains. For example, for the mask 255.255.255.0 you should specify 24 as the fifth parameter.

   - To remove an entry from the list, select a network and click Remove.

   The relay hosts on trusted networks are considered not to be potentially operated by spammers, open relays, or open proxies. A trusted host could conceivably relay spam, but will not originate it, and will not forge header data. DNS blacklist checks will never query for hosts on these networks.
