The value shown is not the limit, it is the observed number of failed cohorts, the question is, why did the transport get throttled... > slow unix - - n - 1 smtp > -o syslog_name=postfix-slow > -o smtp_helo_timeout=10 > -o default_destination_concurrency_failed_cohort_limit=0 This is a queue manager setting, not a delivery agent setting, so no point putting it in master.cf. Wrong variable also. > or in main.cf > slow_destination_concurrency_failed_cohort_limit = 0 This is what you should have in main.cf, however there is a bug in either the implementation or the documentation and the queue manager is looking for: slow_concurrency_failed_cohort_limit not slow_destination_concurrency_failed_cohort_limit This applies also to <transport>_concurrency_positive_feedback <transport>_concurrency_negative_feedback which are documented to be: <transport>_destination_concurrency_positive_feedback <transport>_concurrency_negative_feedback but the "_destination" was left out of the implementation. Sorry about that. Thanks for uncovering the bug. For now you can set both variables: # Temporary alias, to work around 2.5.5 scheduler parameter name bug slow_concurrency_failed_cohort_limit = $slow_destination_concurrency_failed_cohort_limit # Documented interface slow_destination_concurrency_failed_cohort_limit = 0 -- Viktor.
