I'm on build 9560.  I host multiple domains, primarily for family and family owned businesses.  I do not have a staff to perform detailed analysis.  I tend to try to use content filtering to get through whatever the latest SPAM/Virus/extortion fad is.  It seems to me that the content filtering is not working.

I have multiple rules setup, some looking at headers, some at subjects, some at the message as a whole.  Earlier today I added about two dozen new conditions to existing rules, none using wildcards.  Throughout the afternoon I continue to receive messages that match the phrases I added to "delete message" rules.

What am I doing wrong, or are the content filtering rules not working right for others?
