SpamAssassin Spam Filter – Configuring Black and White Lists

To add entries to the black or white list:

  1. Go to the Black List or the White List tab of the Tools &
    Settings
    > Spam Filter 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:

Select the entries on the corresponding tab and click Remove.
