+# This class provides rate-limiting for outgoing SMTP, using postfwd
+# it is configured with some limits that seem reasonable for a generic

+#
+# . 150 recipients at a time
+# . no more than 50 messages in 60 minutes
+# . no more than 250 recipients in 60 minutes.
+#
+# This class could be easily extended to add overrides to these rules,
+# maximum sizes per client, or additional rules
