Mailing lists for programs are typically full of problem reports. Here is the reverse - the equivalent of a thoroughly happy baby-birth story in the middle of a book on childbirth and all that can go wrong with it.
I have been running SA 2.55 for 17 days on my own account. I have RBL checks turned on and Bayes trained with about 1800 spams and 1800 non-spams, both sets carefully checked manually. This is detailed at: http://www.firstpr.com.au/web-mail/Postfix-SA-Anomy-Maildrop/ This is on Red Hat 7, calling SpamAssassin from Courier Maildrop's .mailfilter file, with all the mailing list messages previously sorted so they don't go through SpamAssassin. Messages which are not deemed to be spam go through Anomy Sanitizer to defang suspect HTML and attachments and to filter out messages with executable attachments. After a week I adjusted the scoring of Bayes mid range and higher scores upwards. I have the threshold set to the default 5.0. Extrapolating those changes back to include the first week, I have this happy result: 0 false positives. 6 false negatives. 630 spams correctly detected. ~350 non-spam emails correctly identified as non-spam. This is a 99.06% success rate. The highest score of the non-spam messages was 3.6 - most scores were negative. The scores of the false negatives, arranged by Bayes score, were: Bayes range Total score 1-10% 3.7 (Just a few lines of invalid-looking HTML which Netscape 7.02 would not render, pointing to spammer's web sites.) 44-50% 2.8 (Base 64 encoded. I will write about this in a separate message.) 44-50% 4.9 (Simple HTML - "exonerate your debt": X-Spam-Status: No, hits=4.9 required=5.0 tests=BAYES_44, CLICK_BELOW, CONSOLIDATE_DEBT, HTML_60_70, HTML_FONT_BIG, HTML_FONT_COLOR_BLUE, HTML_FONT_COLOR_GRAY, HTML_FONT_COLOR_RED, HTML_FONT_COLOR_UNSAFE, HTML_LINK_CLICK_HERE, HTML_SHOUTING3, LOW_PAYMENT, MISSING_MIMEOLE, MISSING_OUTLOOK_NAME, REMOVE_PAGE, SUBJ_YOUR_DEBT ) 50-56% 4.2 ("attractive 43 yr old swf", quoted printable: X-Spam-Status: No, hits=4.2 required=5.0 tests=BAYES_50, CLICK_BELOW, EXCUSE_3, FROM_HAS_MIXED_NUMS, MISSING_MIMEOLE, MISSING_OUTLOOK_NAME, NEVER_ANOTHER, REMOVE_PAGE ) 56-60% 2.4 (Short HTML with two links.) 56-60% 4.4 (Plain text with link to spammer's site. X-Spam-Status: No, hits=4.4 required=5.0 tests=BAYES_56, NO_REAL_NAME, PRIORITY_NO_NAME, SEMIFORGED_HOTMAIL_RCVD ) So only two of the spams were scored below the highest non-spam. I regard this as highly successful and salute all those who contributed to Spam Assassin.
