Actually I did reduce the smtpd_client_connection_count_limit and
smtpd_client_connection_rate_limit values, but server still unable to
handle those traffic, and the problem was getting worse since legitimate
email also became delayed. But there is one thing that I suspect, before
I tuned sysctl configuration, the server still can handle the traffic,
but after I change the value of kern.maxfiles, kern.maxfilesperproc,
kern.ipc.somaxconn and net.inet.tcp.inflight.enable, after that server
got rebooted. Is there any chances I misconfigured those values?
