Administrator Guide
split files out to a number of subdirectories to keep lookups fast. This option correlates to the hash_
queue_depth directive and defaults to 2, which is suitable for most moderate and even relatively
large installations. Because the number of directories in use increases the search time for object
seeks, using too high a value here can be harmful to performance.
Name of queue dirs split across subdirs
Postfix uses a number of queues to organize messages with varying states and destinations.
Each of these queues can be configured to use hashed subdirectories. If a queue is selected
here, it will be stored in a hashed subdirectory. In some cases, a queue must not be listed here
as performance will be severely impacted, specifically the world-writable mail drop directory. The
defer log file directory, on the other hand, must be stored in hashed directories or performance
will suffer. This option corresponds to the hash_queue_names directive and defaults to
incoming,active,deferred,bounce,defer,flush and is rarely necessary or beneficial to alter this
configuration.
Max number of Received: headers
A message that contains more Received: headers than this will bounce. An extremely large number
may indicate a mail loop or a misconfigured mail server somewhere in the path of this message.
This option correlates to the hopcount_limit directive and defaults to 50. This value rarely needs to
be altered from its default.
Time in hours before sending a warning for no delivery
If a message cannot be delivered immediately, it will be queued for later delivery. After this number
of hours, if the message still cannot be delivered, a warning will be sent to the sender notifying them
that the server has been unable to send the message for a specified time. This correlates to the
delay_warning_time directive and defaults to not sending a warning.
Network interfaces for receiving mail
This option configures the network addresses on which Postfic will accept mail deliveries. By
default, Postfix will accept mail on every active interface. Here, Postfix will accept the variables
discussed earlier. This option configures the inet_interfaces directive.
Idle time after internal IPC client disconnects
This option sets the time in seconds when an internal IPC client will disconnect. This allows servers
to terminate voluntarily. This feature is used by the address resolution and rewriting clients. This
option correlates to the idle_time directive and defaults to 100 seconds. This option should never
need to be altered under normal circumstances.
Timeout for I/O on internal comm channels
This option determines the amount of time in seconds the server will wait for I/O on internal
communication channels before breaking. If the timeout is exceeded, the server aborts with a fatal
error. This directive corresponds to the ipc_timeout directive and defaults to 3,600 second (60
minutes).
