"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

the threshold is 1-9  isnt 7 more strict?
sorry your right
When the SCL value for a specific message is equal to or higher than the SCL reject threshold, the Content Filter agent deletes the message and sends a rejection response to the sending system. You can customize the rejection response. In some cases, a non-delivery report (NDR) is sent to the original sender of the message. If the SCL value for a message is lower than the SCL delete and SCL reject threshold values, the Content Filter agent does not delete or reject the message. Instead, the Content Filter agent compares the SCL value to the SCL quarantine threshold.

hello r3nder.  All the settings look fine.    not sure what else  it could be?
I can tell you this - it is something iin the [BODY] of that email and it is something that your filter is seeing as spam. Most of the time it is something you think would not be picket up. but there is something in the email. It could also be as blatent as a yahoo advertisement at the bottom.
My recomendation is get a copy of the email sent to you on another yahoo account so you can see it
