Typical input capacity of a Postfix mail server is over 100 messages
per second (sometimes 10s of messages per second if performing CPU-
intensive content filtering). This includes the cost of writing
the message to disk, and related processing.
The cost of rejecting 1-10 messages per minute is negligible.
