You can certainly try, and report your findings. Tried the above setup. It does not help. We have much more 421 with this approach than we had with our former setup. We will now try the following transport settings (based on a recent Wietse sugestion): slow unix - - - - - smtp -o syslog_name=postfix-slow -o default_destination_rate_delay=1s -o default_destination_recipient_limit=20 -o smtp_connection_cache_on_demand=no As usual we will be reporting here the results. Thank you for your time and good will. M.
