I tried to set slow_destination_concurrency_failed_cohort_limit = 0, and send
20 messages with number of recipients is 5 for each message (I used a self
made JAVA program, and re-establish SMTP connection to my Postfix server for
each message), slow_destination_rate_delay = 300s, the first message has
been deferred but the rest of the messages in the active queue just been
deferred, the rest messages of the have also been deferred at once. Pls find
my configuration and logs below. Thx.
# master.cf
slow unix - - n - 1 smtp
-o syslog_name=postfix-slow
-o smtp_helo_timeout=10
# main.cf
slow_destination_rate_delay = 300
slow_destination_concurrency_limit = 2
slow_destination_recipient_limit = 5
slow_connection_cache_destinations =
!yahoo.com,!yahoo.com.hk,!yahoo.com.cn,!yahoo.com.tw
slow_destination_concurrency_failed_cohort_limit = 0
slow_connection_cache_time_limit = 0
slow_never_send_ehlo = yes
slow_helo_timeout = 10
slow_connect_timeout = 5
