How do I tell the LPL spam filter to always tag messages from certain senders as spam (create a blacklist)?

ssh to an LPL solaris server 
Use your favorite editor (e.g., vi or pico) to edit this file: 
/home/yourusername/.spamassassin/user_prefs 
and add a "blacklist_from sender-address" line for each address or class of addresses.

Here are a few examples:

blacklist_from somespammer@spamsite.com 
blacklist_from anotherone@spam.domain.edu 
blacklist_from *@spamalot.com

If you do not know how to use a unix editor (e.g., vi or pico) to make that type of change, send email to sys to request that it be done for you.
