Hi Zhang!

Server has been running great for about a year.  I am trying (for the first time) to use throttling.  The plugin is being loaded:

2017-09-13 23:19:26 INFO Starting iRedAPD (version: 1.9.0, backend: mysql), listening on 127.0.0.1:7777.

2017-09-13 23:19:26 INFO Loading plugin: sql_alias_access_policy
2017-09-13 23:19:26 INFO Loading plugin: amavisd_wblist

Other iRedAPD features are working, such as greylisting and amavis.

I have another server that uses my iredmail server as a relayhost.  I added the other server's IP to postfix mynetworks and to iredapd MYNETWORKS. Relay works fine.

I want to throttle emails coming from the other server, for example, 50 msgs per hour. So I did:

INSERT INTO throttle (account, kind, priority, period, msg_size, max_msgs, max_quota)
VALUES ('other server ip address', 'external', 10, 3600, 0, 50, 0);

However, when messages are relayed from the other server, I don't see anything about throttling in the iredapd.log.  I don't see any entries being created in the throttle_tracking table.

How can I tell whether throttle is working?

Does being in MYNETWORKS exempt that host from throttling?

PS - I just tried dropping the msg limit down to 3 and then sending multiple test msgs. They all went through so I'm not getting any throttling yet.
