Spamassassin at the Tech Computer Center

You can add whitelists and blacklists. Use a whitelist to identify the “good guys,” senders that you definitely want to see. Use a blacklist to identify sites you consider spam.

These will assign a -100 and +100 score respectively. Here are some examples:

whitelist_from *.nmt.edu  
blacklist_from spammer@spam.comments

Use the * character as a “wild card” to match parts of the address.

You can change the spam score limit by adding to your .spamassassin/user_prefs a line like this, where the number is the spam score limit value you want:

required_hits 7.5

Your .spamassassin/user_prefs file will have more examples of whitelists and blacklists. See also Section 4.2, “ Example of a user_prefs file ”.
