This morning I had a bunch of messages rejected with the error "Too much
traffic", logged by this ACL.
deny domains = +sms_domains
ratelimit = 100 / 1h / per_rcpt / leaky / $local_part@$domain
message = Too much traffic to $local_part@$domain\nlimit is
$sender_rate_limit/$sender_rate_period
The problem is that there is no other traffic logged to those addresses in the
last 10 days of logs. If the ACL was working as I would expect, it should not
have rejected any traffic.
I would expect it to allow through the first 100 messages to an address that
had not been used previously, then start rejecting only if the rate exceeded
100 messages per hour to the recipient address. This ACL has been in place for
some time and has appeared to work as expected in the past.
Is there an obvious error that I have missed or a known bug that might have
been triggered?
