To add entries to the black or white list:


1. Go to the corresponding tab of the Tools & Settings > Spam Filter Settings page.


2. Click Add Addresses.


3. Provide the list of entries you want to add to the list.

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@spammers.net, user?@spammers.net, *@spammers.net. Specifying *@spammers.net will block the entire mail domain spammers.net. If you use a Windows-based server, also specify what to do with messages coming from the specified addresses.


4. Click OK.


To remove entries from the black or white list:
