Filter Email Before SpamAssassin?

Is it possible to apply the email filters before SpamAssassin analyzes the email? I receive a lot of spam and adjusted the scoring to eliminate it. However, some valid messages are being flagged as spam.

The SpamAssassin whitelist won't work in all cases, because the filtering is based on the contents of TO and SUBJECT, not FROM. Therefore, I can enable the email to go through by using filters.

Unfortunately, many of these messages being passed through are flagged as "***SPAM***" in the subject line, even though they are valid messages.

Is there a way to pass these messages through, without having them flagged as spam?

Thank you for your reply. I referred to the white list in my original message. Unless I'm mistaken, the white list only allows you to enter "FROM" addresses or domains. However, I want to pass through messages based on "TO" and "SUBJECT".
