You are using VERP - every message will be sent with one recipient only, so you can safely remove this setting. > slow_destination_concurrency_limit = 2 > > slow_destination_concurrency_failed_cohort_limit = 4 You are limiting yourself to eight temporary failures before Yahoo! is declared dead. A higher failed_cohort_limit (e.g. 2000) would allow far more temporary failures before delivery to Yahoo is suspended. I suggest you give it a try once and compare the results. I further suggest checking you logs and looking for scache entries (conn_use=x in delivery lines and it's own scache entries).
