Does the "lost connection" happen because Postfix makes multiple connections at the same time? Try this example: /etc/postfix/main.cf: transport_maps = hash:/etc/postfix/transport slow_destination_concurrency_limit = 1 slow_initial_destination_concurrency = 1 slow_destination_concurrency_failed_cohort_limit = 10 /etc/postfix/transport: example.com slow: /etc/postfix/master.cf: # service type private unpriv chroot wakeup maxproc command slow unix - - n - - smtp -o smtp_connection_cache_on_demand=no for "example.com" specify the problem domain name (not hostname or IP address).
