Hello, Some of the biggest french provider are using CSI “cloudmark sender intelligence” : the big problem wih CSI cloudmark is that they don’t accept many simultaneous connexions.
i always get a log like “too many connexion, slow down”.... so i made the following configuration : In /etc/postfix.transport wanadoo.com slow: wanadoo.fr slow: In /etc/postfix/master.cf slow unix – - n – 5 smtp -o syslog_name=postfix-slow -o smtp_destination_concurrency_limit=3 -o slow_destination_rate_delay=1 In /etc/postfix/main.cf transport_maps = /etc/postfix/transport slow_destination_recipient_limit = 20 slow_destination_concurrency_limit = 2 but i keep have some trouble in my logs... In the CSI advice, they says : if you have 100 Messages to deliver to this server, the better way is to open 1 connection and send 100 messages instead of opening 100 connexions delivering 1 message each... do i have to change the slow_destination_recipient_limit parametter to follow this advice ? Thanks in advance Nico Angenon
