A Spam has come in my network. When I looked as Score , it was showing SHA = -15. After checking Mail log , i saw following statement :
System Defined Header Analysis was successful in evaluation of rule(s) for Message ID, with Score details: <msgid:score> -|<11400042:<822-Headers:Missing Headers "To:", "From:", "Subject:">:<3> <822-Headers:Missing "To" "CC">:<3> <Body:Size greater than 500 KB>:<-21>>|
Although in SHA Configuration under AntiSpam option, score of Body size greater than 500 KB = 21 but why it is giving score in negative ?
Kindly confirm urgent
