Postfix logs: "timeout after xxx from host[address]" where xxx is a the last protocol state. Where do your connections time out? The Postfix SMTP sever by default times out after 300s (5 minutes). https://www.postfix.org/postconf.5.html#smtpd_timeout Shorter timeouts may happen in firewalls, NATs, and so on. Under overload, That time limit reduces to 10s, is enforced for receiving an entire command. Also, under overload Postfix enforces a minimum data rate (smtpd_min_data_rate). https://www.postfix.org/STRESS_README.html#adapt https://www.postfix.org/postconf.5.html#smtpd_per_request_deadline https://www.postfix.org/postconf.5.html#smtpd_min_data_rate Wietse _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
