I apologize if this topic seems basic or I'm missing something obvious here, but after much googling and looking to Ralph's book for answers, I am still unclear on this...
Despite creating a slow transport for yahoo and verifying that the unix socket 'slow' exists, it seems that it's not being used. Our connections to yahoo are still occurring at a rate faster than specified here in main.cf params and there is no 'postfix-slow' anywhere in my maillogs. This is true for mail originating from the postfix host sent from CLI and for mail accepted for relay (from another local trusted machine) bound for yahoo. master.cf:: slow unix - - n - 1 smtp -o syslog_name=postfix-slow main.cf:: slow_destination_rate_delay = 120 slow_destination_concurrency_limit = 1 slow_destination_recipient_limit = 2 slow_connection_cache_time_limit = 0 slow_never_send_ehlo = yes slow_connect_timeout = 5 Thank you for any help. - Andrew
