We are considering using smtpd_client_message_rate_limit on our central (internal) mail servers to protect against mail floods when some departmental server goes crazy. Since normal mail from any particular client sometimes comes in bursts, I am considering increasing anvil_rate_time_unit. Are there any side effects to increasing this parameter? I am thinking about 10 minutes instead of 1 minute.
We are running Postfix 3.2.0 on RHEL6. Thanks, Larry M. Rosenbaum Oak Ridge National Laboratory
