# DO NOT EDIT THIS FILE. EDIT THE MAIN.CF FILE INSTEAD. THE STUFF # HERE JUST SERVES AS AN EXAMPLE. # # This file contains example settings of general Postfix resource # control parameters. # # Controls that are specific to message delivery transports are # described in the respective sample-transportname.cf file. # The bounce_size_limit parameter limits the amount of original # message context in bytes that is sent in a non-delivery notification. # bounce_size_limit = 50000 # The command_time_limit parameter 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. # # Note: if you set this time limit to a large value you must update the # global ipc_timeout parameter as well. See sample-misc.cf for details. # command_time_limit = 1000 # The default_process_limit parameter specifies the default limit # on the number of Postfix child processes that provide a given # service. # default_process_limit = 50 # The deliver_lock_attempts parameter limits the number of attempts # to acquire an exclusive lock on a mailbox or other file. # deliver_lock_attempts = 5 # The deliver_lock_delay parameter specifies the time between attempts # to acquire an exclusive lock. # # Time units: s (seconds), m (minutes), h (hours), d (days), w (weeks). # The default time unit is s (seconds). # deliver_lock_delay = 1s # The duplicate_filter_limit parameter limits the number of addresses # remembered by the duplicate filter for alias, virtual, etc. # expansion. # duplicate_filter_limit = 1000 # The fork_attempts parameter limits the number of attempts to # fork() a process. # fork_attempts = 5 # The fork_delay parameter specifies the delay between attempts to # fork() an external process. # # Time units: s (seconds), m (minutes), h (hours), d (days), w (weeks). # The default time unit is s (seconds). # fork_delay = 1s # The header_size_limit parameter limits the amount of memory in # bytes used for storing a message header. If a header is larger, # the remainder of the header is descarded. # header_size_limit = 102400 # The header_address_token_limit limits the amount of memory that # Postfix will spend while rewriting addresses in message headers. # The limit is expressed as a token count. Tokens beyond the limit # are discarded. # header_address_token_limit = 10240 # The line_length_limit parameter limits the amount of memory in # bytes used for handling input lines. Longer lines are chopped up # into pieces and reconstructed upon delivery. # line_length_limit = 2048 # The message_size_limit parameter limits the total size in bytes of # a message, including envelope information. # message_size_limit = 10240000 # The qmgr_message_active_limit parameter limits the number of # messages in the active queue. # qmgr_message_active_limit = 1000 # The qmgr_message_recipient_limit parameter limits the number of # in-memory recipients. This parameter also limits the size of the # short-term, in-memory destination status cache. # qmgr_message_recipient_limit = 1000 # The queue_minfree parameter 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. # queue_minfree = 0 # The stale_lock_time parameter limits the time after which a stale # lock is removed. This is used for delivery to file or mailbox. # # Time units: s (seconds), m (minutes), h (hours), d (days), w (weeks). # The default time unit is s (seconds). # stale_lock_time = 500s # The transport_retry_time parameter specifies the time between # attempts by the queue manager to contact a broken message delivery # transport. # # Time units: s (seconds), m (minutes), h (hours), d (days), w (weeks). # The default time unit is s (seconds). # transport_retry_time = 60s
