I am running CentOS 5.3 x86. I have Courier-imap, postfix, and amavis setup. It's working just fine, and has been for a couple of months. However, instead of using client side filters, I want to switch to a server side filter. Already, spam is being marked as ***SPAM*** (In the subject line). Now I would like all spam to get moved to a user's spam directory. Spam should go to this directory: /home/vmail/domain.tld/username/.Spam How can I do this? I have maildrop installed under /usr/local/bin/maildrop Postfix is setup via MySQL Virtual Users similar to this tutorial: http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-centos-5.3-x86_64 However it was a while ago that I did this, and I forget which tutorial I used.
