# 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 Postfix parameters that # control the fast flush service, which is the code that implements # fast ETRN and fast "sendmail -qR". # The fast_flush_domains parameter specifies what destinations are # eligible for per-destination logfiles with mail that is queued to # those destinations. # # When a destination is eligible for "fast flush" logfiles, ETRN and # "sendmail -qR" are implemented by delivering only messages that # are listed in the logfile for that destination (in fact, Postfix # will deliver to all recipients of those messages, regardless of # their destination, but that is not an issue when you relay mail # for an eligible site). # # When a destination is not eligible for "fast flush" logfiles, ETRN # and "sendmail -qR" are implemented simply by attempting to deliver # all queued mail. That's the slow service that Postfix used to # implement before 20001005. # # By default, Postfix maintains "fast flush" logfiles only for # destinations that the Postfix SMTP server is willing to relay to # (see the relay_domains parameter in sample-smtpd.cf). # # Specify "fast_flush_domains =" to disable the feature altogether. # fast_flush_domains = $relay_domains #fast_flush_domains = # The fast_flush_purge_time parameter controls how long an empty # per-destination "fast flush" logfile is allowed to live. # # You can specify the time as a number, or as a number followed by # a letter that indicates the time unit: s=seconds, m=minutes, h=hours, # d=days, w=weeks. The default time unit is days. # fast_flush_purge_time = 7d # The fast_flush_refresh_time parameter controls how long a non-empty # per-destination "fast flush" logfile is allowed to remain unread # before its contents need to be refreshed. The contents of a logfile # are refreshed by requesting delivery of messages listed in the # logfile. # # You can specify the time as a number, or as a number followed by # a letter that indicates the time unit: s=seconds, m=minutes, h=hours, # d=days, w=weeks. The default time unit is hours. # fast_flush_refresh_time = 12h
