Hello- I followed the 'Virtual Users And Domains With Postfix, Courier And MySQL (Fedora Core 5)' howto, and added maildrop mail filtering to move messages marked as spam to each user's Junk folder. Now I would like to whitelist senders that I have placed in a mysql database. There are some guides on the web, but since the howto does not create teh same tables as those in other guides I am unsure how to proceed. Any help would be appreciated. Thank you in advance for your time.
