hello,

think i´ve done right but the blacklist does not work for me ?!?

inside MailScanner.conf:
Is Definitely Spam =  %rules-dir%/spam.blacklist.rules

/etc/MailScanner/rules
-rw-r--r--  1 root root  518 Feb  1 11:42 spam.blacklist.rules
-rw-r--r--  1 root root 1106 Feb  1 10:22 spam.whitelist.rules

spam.blacklist.rules:
To:             spam at host.domain12345.de
From:           andreas at domain135.de

host.domain12345.de is the mailscanner host, the other is my personal mail.

nothing will be blocked and im sure the one setting in ms conf is enough, or
not ?

didnt found something in the archive, dont hit me if im to silly to search
;)

greetings
andy
