[exim] Ratelimit Clients to Relay host

Hi All,

I have relay server, need to limit number of relayed messages to
2000/hour/Client , need to drop additional mail after that until rate
period ends.

I tried settings below with no luck.

Any ideas

Thanks






acl_check_rcpt:

defer ratelimit = 2000 /1h / strict / $sender_host_address
message = Sender rate exceeds $sender_rate_limit messages per
$sender_rate_period
log_message = Local sender rate limit $sender_rate / $sender_rate_period
