This option sets the "bounce_size_limit" postfix variable.
<tag/Command time limit/
The "Command time limit" option limits the amount of time for
delivery to external commands. This limit is used by the local
delivery agent, and is the default time limit for delivery by the
pipe mailer. This option sets the "command_time_limit" postfix variable.
Note: if you set this time limit to a large value you must update the
global "Ipc timeout" option as well.
<tag/Default process limit/
The "Default process limit" option specifies the default limit
on the number of Postfix child processes that provide a given
service. This option sets the "default_process_limit" postfix
variable.
<tag/Deliver lock attempts/
The "Deliver loack attempts" option limits the number of attempts
to acquire an exclusive lock on a mailbox or other file. This
option sets the "deliver_lock_attempts" postfix variable.
<tag/Deliver lock delay/
The "Deliver lock delay" option limits the time in seconds between
attempts to acquire an exclusive lock. This option sets the
"deliver_lock_delay" postfix variable.
<tag/Duplicate filter limit/
The "Duplicate filter limit" option limits the number of addresses
remembered by the duplicate filter for alias, virtual, etc.

<tag/Fork delay/
The "Fork delay" option specifies the delay in seconds between
fork() attempts. This option sets the "fork_delay postfix variable.
<tag/Header size limit/
The "Header size limit" option limits the amount of memory in
bytes used for processing a message header. If a header is larger,
the remainder of the entire message is treated as message body.
This option sets the "header_size_limit" postfix variable.
<tag/Line length limit/
The "Line length limit" option limits the amount of memory in
bytes used for handling input lines. Longer lines are chopped up
into pieces and reconstructed upon delivery. This option sets
the "line_length_limit" postfix variable.
<tag/Message size limit/
The "Message size limit" option limits the total size in bytes of
a message, including envelope information. This option sets the
"message_size_limit" postfix variable.
<tag/qmgr message active limit/
The "qmgr message active limit" option limits the number of
messages in the active queue.
This option sets the "qmgr_message_active_limit" postfix variable.
<tag/qmgr message recipient limit/
The "qmgr message recipient limit" option limits the number of
in-memory recipients. This option also limits the size of the
short-term, in-memory destination status cache.
This option sets the "qmgr_message_recipient_limit" postfix variable.
<tag/Queue minfree/
The "Queue minfree" option specifies the minimal amount of free
space in bytes in the queue file system. This is currently used by
the SMTP server to decide if it will accept any mail at all.
This option sets the "queue_minfree" postfix variable.
<tag/Stale lock time/
The "Stale lock time" option limits the time after which a stale
lock is removed. This is used for delivery to file or mailbox.
This option sets the "stale_lock_time" postfix variable.
<tag/Transport retry time/
The "Transport retry time" option specifies the time in seconds
between attempts by the queue manager to contact a broken message
delivery transport. This option sets the "transport_retry_time"
postfix variable.
