Hello, I have added an email address in the policyd->whitelist_sender table in my MySQL database however this users email still gets marked as spam, I believe it may be white listed however the test email I am using will score high and is still being flagged as spam.

Creating a custom config file in /etc/mail/spamassassin/ with the line: "score USER_IN_WHITELIST -1000.000" along with "whitelist_from email@address" allows the test spam emails through. However this approach is not satisfactory to me because I will need to add whitelisted emails to the MySQL database. How do I achieve this using the whitelists in the policyd MySQL tables?

Thanks!
