From fa4c4b138e4723938278f6658f7dcf56ba349604 Mon Sep 17 00:00:00 2001 From: dofl Date: Sun, 9 Jun 2019 07:39:36 +0200 Subject: [PATCH] Update main.cf Added the delay_warning_time (http://www.postfix.org/postconf.5.html#delay_warning_time) with 4 hours as setting. Postfix will inform the user that the e-mail has not been delivered, but that it will try for the next 5 days. There is also a setting called confirm_delay_cleared (http://www.postfix.org/postconf.5.html#confirm_delay_cleared), but according to the Postfix this can lead to a sudden burst of notifications at the end of a prolonged network outage. --- data/conf/postfix/main.cf | 1 + 1 file changed, 1 insertion(+) diff --git a/data/conf/postfix/main.cf b/data/conf/postfix/main.cf index 95301c43..bd8f76ed 100644 --- a/data/conf/postfix/main.cf +++ b/data/conf/postfix/main.cf @@ -20,6 +20,7 @@ broken_sasl_auth_clients = yes disable_vrfy_command = yes maximal_backoff_time = 1800s maximal_queue_lifetime = 5d +delay_warning_time = 4h message_size_limit = 104857600 milter_default_action = accept milter_protocol = 6
