Not really - postfix processes stay around "max_idle" seconds (default
100) waiting for further work before exiting. If requests exceed the
available number of service processes, they are typically queued
anyway. Even the smtpd process - while the TCP connection requests
won't be serviced immediately, the remote TCP stack will keep retrying
for around 2 minutes, and the remote process will retry for typically 5
days. You really only need to worry if you are continuously up against
the process limit.
