example, a system filter could set a value indicating how likely it is that a
message is junk mail.
-.vitem &$spam_$&&'xxx'&
+.vitem &$spam_score$& &&&
+ &$spam_score_int$& &&&
+ &$spam_bar$& &&&
+ &$spam_report$& &&&
+ &$spam_action$&
A number of variables whose names start with &$spam$& are available when Exim
is compiled with the content-scanning extension. For details, see section
