I've read most of the OSIRUSOFT and when I disabled these setting: score RCVD_IN_OSIRUSOFT_COM 0 score X_OSIRU_DUL 0 score X_OSIRU_DUL_FH 0 score X_OSIRU_OPEN_RELAY 0 score X_OSIRU_SPAMWARE_SITE 0 score X_OSIRU_SPAM_SRC 0 I notice an increase of spam not being flaged. Should I have increase/decrease the spam score? thanks, Lou.
