Enable user management of spam filtering

If you want to enable user-level management of spam filters in Plesk for all users that have spamassassin enabled, you can use this query:

INSERT INTO Permissions (id,permission,value) 
SELECT perm_id,'manage_spamfilter',true FROM mail WHERE spamfilter = true;
