Why can I get MailScanner to process some SpamAssassin options?
MailScanner only uses 3 pieces of information returned from SpamAssassin: • The number of hits scored • The threshold above which a message is deemed to be spam • The list of matching rule names So changing SpamAssassin items like the report style (use_terse_report) will have no effect as everything else is discarded. This was coded by design to reduce the number of headers MailScanner has to parse.
