Not the parameters you showed, they are queue-manager parameters, not SMTP client parameters. > Sorry but this was just an example, i put these parameters only to > understand if it possible or not ... The parameters that are relevant to smtp(8) are specified in the smtp(8) manpage: http://www.postfix.org/smtp.8.html > You means that tuning smtp instance is not possible trough " -o" > commandline ? No, tuning queue-manager parameters is not possible through "-o" overrides in the master.cf entry for smtp(8). > SO this kind of settings is not correct ?? > > # > ========================================================================== > # service type private unpriv chroot wakeup maxproc command + args > # (yes) (yes) (yes) (never) (100) > # > ========================================================================== > smtp inet n - n - - smtpd > > slowsmtp unix - - n - - smtp > -o default_destination_concurrency_failed_cohort_limit=1 > -o default_delivery_slot_loan=3 > -o default_delivery_slot_discount=50 > -o default_delivery_slot_cost=5 > -o default_initial_destination_concurrency=5 > -o default_destination_recipient_limit=50 > -o default_destination_concurrency_limit=20 > -o default_destination_rate_delay=5s Indeed this is not correct.

And you are trying to change parameters you really should not be changing. If you can't explain how the "default_delivery_slot_<mumble>" variables achieve your goals, you should not (attempt to) modify these parameters. -- Viktor.
