Thanks for all the replies. I wonder if there are any help files for Spam Assassin. I don't see any in the panel, and I cannot understand the following (from the Spam Assassin configuration page):
"Assign scores (the number of points for a hit) to a given test. Scores can be positive or negative real numbers or integers. "SYM-BOLIC_TEST_NAME" is the symbolic name used by SpamAssassin for that test; for example, 'FROM_ENDS_IN_NU'. If only one valid score is listed, then that score is always used for a test. If four valid scores are listed, then the score that is used depends on how SpamAssassin is being used. The first score is used when both Bayes and network tests are disabled. The second score is used when Bayes is disabled, but network tests are enabled. The third score is used when Bayes is enabled and network tests are disabled. The fourth score is used when Bayes is enabled and net-work tests are enabled. Setting a rule's score to 0 will disable that rule from running."
This obviously wasn't written for laymen like me. Are there any plain English help files available for this and other panel features? Thanks.
