Delivery Rates
This page contains the options for setting the default rate and concurrency limits for all Postfix
components. These rates can usually be overridden within their respective configuration sections.
Max number of parallel deliveries to the same destination
This option specifies the maximum number of deliveries that Postfix will perform to the same
destination simultaneously. This option correlates to the default_destination_concurrency_limit
directive and defaults to 10.
Max number of recipients per message delivery
Limits the number of recipients per delivery. This option correlates to the default_destination_
recipient_limit directive and defaults to 50.
Initial concurrency level for delivery to the same destination
Specifies the initial number of simultaneous deliveries to the same destination. This limit applies
to all SMTP, local and pipe mailer deliveries. A concurrency of less than two could lead to a single
problem email backing up delivery of other mail to the same destination. This option configures the
initial_destination_concurrency directive and defaults to 5.
Max time (days) in queue before message is undeliverable
Defines the number of days a message will remain queued for delivery in the event of delivery
problems before the message is sent back as undeliverable. This option configures the maximal_
queue_lifetime directive and defaults to 5 days.
Min time (secs) between attempts to deliver a deferred message
In the event of a delivery deferral, Postfix will wait a specified amount of time before reattempting
delivery. This value also specifies the time an unreachable destination will remain in the destination
status cache. This option correlates to the minimal_backoff_time directive and defaults to 1000
seconds.
Max time (secs) between attempts to deliver a deferred message
Specifies the maximum amount of time between delivery attempts in the event of a deferred
delivery. This option configures the maximal_backoff_time directive and defaults to 4000 seconds.
Time (secs) between scanning the deferred queue
Specifies the time in seconds between queue scans by the queue management task. This option
correlates to the queue_run_delay and defaults to 1000 seconds.
Transports that should not be delivered
This field specifies which delivery transports, if any, defined in the Transport Mapping section will
not have their messages sent automatically. Instead, the messages will be queued and delivered
manually using the sendmail -q command. This option correlates to the defer_transports directive
and contains nothing by default.
