How can I adjust my spam filter?

In order to adjust your spam filter go to the following link :

Login and enter your full email address and password in the “Email Login” section. (refer to How to check your email online). Click on Permissions and make sure ‘spam filter management’ is set to ‘Yes’.

Then click on ‘Spam Filter’ button

1. If you wish to adjust the spam filter’s sensitivity, type the desired value in the “The score that a message must receive to qualify as spam” box.

SpamAssassin performs a number of different tests on the 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 MEDICATION AT LOW PRICE!!!” in the 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 your users receive lots of spam messages with the current setting and you want to make the filter more sensitive, try setting a lesser value in the The score that a message must receive to qualify as spam box; for example, 6.

When your users are missing e-mails because your spam filter thinks they are junk, try reducing the filter sensitivity by setting a higher value in the “The score that a message must receive to qualify as spam” box.

2. Specify how to mark messages recognized as spam.

To add a desired combination of symbols or words to a message subject to identify it as spam, type it into the “Add the following text to the beginning of subject of each message recognized as spam” box. If you do not want the spam filter to modify the message subject, leave this box blank. If you want to include the number of points that the messages score in the subject line, type _SCORE_ in this box.

3. If you do not want to receive e-mail from specific domains or individual senders, click the Black List tab and then add the respective entries to the spam filter’s black list:

To add entries to the black list, click Add Addresses. If you have a list of entries stored in a file, click Browse to specify it, and then click OK. Otherwise, select the From List option, and type the e-mail addresses into the E-mail addresses box. Place each address in one row, or separate addresses with a comma or a white space. You can use an asterisk (*) as a substitute for a number of letters and a question mark (?) as a substitute for a single letter.

For example: address@spammers.net, user?@spammers.net, *@spammers.net. Specifying *@spammers.net will block the entire mail domain spammers.net. To save the entries you added, click OK, then confirm adding, and click OK again.
To remove entries from the black list, under the Black List tab, select the entries and click Remove Selected. Confirm removal and click OK.

4. If you want to be sure that you will not miss e-mail from specific senders, click the White List tab, and then add e-mail addresses or entire domains to the spam filter’s white list:

To add entries to the white list, click Add Addresses. If you have a list of entries stored in a file, click Browse to specify it, and then click OK. Otherwise, select the From List option, and type the e-mail addresses into the E-mail addresses box. Place each address in one row, or separate addresses with a comma, a colon, or a white space. You can use an asterisk (*) as a substitute for a number of letters, and question mark (?) as a substitute for a single letter.

For example: address@mycompany.com, user?@mycompany.com, *@mycompany.com. Specifying *@mycompany.com will add to the white list all e-mail addresses that are under the mycompany.com mail domain. To save the entries you added, click OK, then confirm adding, and click OK again.
To remove entries from the white list, under the White List tab, select the entries and click Remove Selected. Confirm removal and click OK.

Once finished with setting up the spam filter, click OK. If the spam filter is still off, you will see the ‘Switch On’ button, so click the Switch On icon, and then OK.

Now all the incoming mail will be filtered on the server side. Please note that, by default, the spam filter does not delete spam mail, it only adds the “X-Spam-Flag: YES” and “X-Spam-Status: Yes” headers to the message, and “*****SPAM*****” text string to the beginning of Subject line of each message recognized as spam.
