I have also run into this problem. My solution was to edit /etc/init.d/clamav-milter to chmod g+w the $SOCKET_PATH after startup (and of course add postfix to the clamav group).
It would be nice if when I upgrade clamav-milter a couple years from now this problem is solved, so I dont spend a day or two wondering what is going on. :) Micah -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
