+#           and the 'du' binary in $ENV{'PATH'} (see below).
+#
+# You will need to modify the postfix DATABASE to add a quota_usage column. 
+# Mysql:
+# 	ALTER TABLE mailbox ADD quota_usage INT(11) NOT NULL DEFAULT '0' AFTER modified, 
+# 	ADD quota_usage_date DATE NOT NULL DEFAULT '0000-00-00' AFTER quota_usage;
+# PostgreSQL:
+# 	ALTER TABLE mailbox ADD COLUMN quota_usage INTEGER NOT NULL DEFAULT 0;
+# 	ALTER TABLE mailbox ADD COLUMN quota_usage_date DATE NOT NULL DEFAULT current_date;
