$ grep -i 'too many' /var/log/maillog
Fix: update smtpd_client_event_limit_exceptions,
smtpd_client_connection_count_limit, or smtpd_client_connection_rate_limit.
$ grep -i 'stress' /var/log/maillog
Fix: increase the SMTP daemon process limit (in master.cf, or
default_process_limit in main.cf), and do "postfix reload".
