Dear,
I will be more accurate. My postfix configuration is like this : I use yahoo domain for exemple : Transport : yahoo.com yahoo: yahoo.fr yahoo: Master.cf yahoo unix - - n - 1 smtp Main.cf yahoo_destination_concurrency_limit = 20 yahoo_destination_rate_delay = 10s yahoo_destination_recipient_limit = 20 When I setup the rate delay this force a concurrency of 1. I also try to setup the cache connection to keep the connection open and send more email per open connection. yahoo_connection_cache_reuse_limit = 15s yahoo_connection_reuse_time_limit = 20s yahoo_connection_cache_time_limit = 1s With this configuration my send are send 1 by 1 to yahoo domain. I would like send the email to yahoo domain according with recommendation of yahoo postmaster advice: 20 simultanous connection and 20 messages send per open SMTP connection and finaly no more than 600 connection to yahoo MX per hour. That why I need the rate delay. I hope I'm more accurate.
