When a message<\/span><span style=\"font-family: \'Times New Roman\',Times,Georgia,serif; color: #010100;\">\'<\/span><span class=\"f_ControlIndent\">s spam score is greater than or equal to this score it will be rejected completely rather than proceed through the rest of the options and possibly be delivered.

Use &quot;0&quot; in this option if wish to disable scanning during the SMTP process, and if you do not want MDaemon to reject any messages regardless of their scores. If SMTP scanning is disabled then a queue-based scan will still be performed on the messages after they are accepted. The default setting for this option is &quot;12.0&quot;.<\/span><\/p>\n\r<p class=\"p_ControlIndent\"><span class=\"f_ControlIndent\">Example,<\/span><\/p>\n\r<p class=\"p_ControlIndent\"><span class=\"f_ControlIndent\">If you have the spam score threshold set to 5.0 and the rejection threshold set to 10.0, then any message with a spam score that is greater than or equal to 5.0 but less than 10.0 will be considered spam and handled according to the rest of your Spam Filter settings. Any message with a spam score greater than or equal to 10.0 will be rejected by MDaemon during the delivery process.<\/span><\/p>\n\r<div style=\"text-align: left; text-indent: 0; padding: 0 0 0 0; margin: 0 3.0625rem 0.8750rem 3.0000rem;\"><table style=\"background-color:#ffffe6; border:solid thin #000000; border-spacing:0;\">\n\r<tr>\n\r<td style=\"vertical-align:top; width:3.1250rem; height:3.1250rem; padding:0.3125rem; border:none\"><p class=\"p_NoFormat\"><img style=\"margin:0;width:3.1250rem;height:3.1250rem;border:none\" src=\".\/images\/lightbulb_on_50_yback.gif\"\/><\/p>\n\r<\/td>\n\r<td style=\"vertical-align:top; padding:0.3125rem; border:none\"><p class=\"p_Notes\"><span class=\"f_Notes\">You should monitor the spam filter<\/span><span style=\"font-family: \'Times New Roman\',Times,Georgia,serif;\">\'<\/span><span class=\"f_Notes\">s performance over time and refine both the spam and rejection thresholds to suit your need. For most people, however, a spam score threshold of 5.0 will catch most spam, with relatively few false negatives (spam that slips through unrecognized) and rarely any false positives (messages flagged as spam that are not). A rejection threshold of 10-15 will cause only messages that are almost certainly spam to be rejected. It is extremely rare that a legitimate message will have a score that high. The default rejection threshold is 12.<\/span><\/p>\n\r<\/td>\n\r<\/tr>\n\r<\/table>\n\r<\/div>\n\r<p class=\"p_ControlHeading\" style=\"page-break-after: avoid;\"><span class=\"f_ControlHeading\">Show heuristic results within SMTP session logs<\/span><\/p>\n\r<p class=\"p_ControlIndent\"><span class=\"f_ControlIndent\">Click this option to log the results of heuristic processing during SMTP sessions to the <a href=\"log_options.html\" class=\"topiclink\">SMTP session logs<\/a>.<\/span><\/p>\n\r<p class=\"p_ControlHeading\" style=\"page-break-after: avoid;\"><span class=\"f_ControlHeading\">Send heuristic results to SMTP clients<\/span><\/p>\n\r<p class=\"p_ControlIndent\"><span class=\"f_ControlIndent\">Click this option to display heuristic processing results inline with SMTP session transcripts. This option is not available when you have your Spam Score rejection threshold set to &quot;0&quot;, meaning that spam will never be rejected because of its score.

For messages that are accepted MDaemon will then perform another, queue-based, scan and treat the messages accordingly, based on their scores and your spam filter configuration. Click this option if you want MDaemon to omit the queue-based scan and treat the results of the initial Spam Filter scan as definitive. This can potentially significantly decrease CPU usage and increase the efficiency of the AntiSpam system. However, only the default SpamAssassin headers will be added to messages when the queue-based scan is omitted. If you have made any changes to the default SpamAssassin headers or specified custom headers in your <\/span><span style=\"font-size: 1.10rem; font-family: \'Courier New\',Courier,monospace; color: #010100;\">local.cf<\/span><span class=\"f_ControlIndent\"> file, those changes and additions will be ignored.<\/span><\/p>\n\r<p class=\"p_ControlHeading\" style=\"page-break-after: avoid;\"><span class=\"f_ControlHeading\">Refuse to accept message if an error occurs during SMTP scanning<\/span><\/p>\n\r<p class=\"p_ControlIndent\"><span class=\"f_ControlIndent\">Click this option if you want a message to be refused when an error is encountered while it is being scanned during the SMTP process.<\/span><\/p>\n\r<p class=\"p_ControlHeading\" style=\"page-break-after: avoid;\"><span class=\"f_ControlHeading\">Subject tag<\/span><\/p>\n\r<p class=\"p_ControlIndent\"><span class=\"f_ControlIndent\">This tag will be inserted at the beginning of the Subject header of all messages that meet or exceed the required spam score threshold. It can contain information about the spam score, and you can use your IMAP message filters to search for it and filter the message accordingly (assuming that you have the Spam Filter configured to continue delivering spam messages). This is a simple method for automatically routing spam messages to a designated &quot;spam&quot; folder. If you want to dynamically insert the message<\/span><span style=\"font-family: \'Times New Roman\',Times,Georgia,serif; color: #010100;\">\'<\/span><span class=\"f_ControlIndent\">s spam score and the value of the required spam threshold then use the tag &quot;<\/span><span style=\"font-size: 1.10rem; font-family: \'Courier New\',Courier,monospace; color: #010100;\">_HITS_<\/span><span class=\"f_ControlIndent\">&quot; for the message<\/span><span style=\"font-family: \'Times New Roman\',Times,Georgia,serif; color: #010100;\">\'<\/span><span class=\"f_ControlIndent\">s score and &quot;<\/span><span style=\"font-size: 1.10rem; font-family: \'Courier New\',Courier,monospace; color: #010100;\">_REQD_<\/span><span class=\"f_ControlIndent\">&quot; for the required threshold.
