How use Spamassassin to blacklist an email address.
1. Log on to the UNIX system.
2. Enter 'cd .spamassassin'.
3. Enter 'pico user_prefs'.
4. Cursor down below the comments about whitelists and blacklists and
enter 'blacklist_from james@geri.duke.edu'. That's a tab between
'from' and 'james'.
5. Add more 'blacklist_from address' entries, each on a separate line, as
needed.
6. Press ctrl-x to exit the editor.
7. Enter 'y' to save the changes.
8. Press 'Enter' to use the existing file name.
9. Log off the geri system.
Note, if email that you wish to see is consistently getting marked as
spam, you can whitelist addresses in the same way you do the blacklist.
