Increase spamassassin bayes99 score

[Nikolaos Milas]

Hello, After relatively long training of bayes filters, we are consistently getting bayes99 score of 3.5 (on spam mails). It seems this is the max score assigned to bayes99. How/where can we increase this value? Config files are at: /etc/amavisd.conf and at /etc/mail/spamassassin/local.cf Spam mails still get through because a higher total score is needed for them to be auto designated as spam. Here is a typical header of such a mail: X-Spam-Flag: NO X-Spam-Score: 5.153 X-Spam-Level: ***** X-Spam-Status: No, score=5.153 tagged_above=-999 required=5.5     tests=[BAYES_99=3.5, BAYES_999=0.2, DATE_IN_PAST_12_24=1.049,     DKIM_ADSP_CUSTOM_MED=0.001, FREEMAIL_FROM=0.001,     HTML_IMAGE_RATIO_06=0.001, HTML_MESSAGE=0.001, IP_LINK_PLUS=0.012,     NML_ADSP_CUSTOM_MED=0.9, NORMAL_HTTP_TO_IP=0.001,     RP_MATCHES_RCVD=-0.313, SPF_HELO_PASS=-0.1, SPF_PASS=-0.1]     autolearn=disabled How should I best handle the issue? I think that raising max score from 3.5 to e.g. 6.0 might do the trick. Any other options?
