       The pickup(8) daemon copies mail from file to the cleanup(8) daemon.   It  could  avoid  message  copying
       overhead  by  sending  a  file  descriptor  instead of file data, but then the already complex cleanup(8)
       daemon would have to deal with unfiltered user data.

       As the pickup(8) daemon is a relatively long-running process, up to an hour may  pass  before  a  main.cf
       change takes effect.  Use the command "postfixreload" command to speed up a change.

       The text below provides only a parameter summary. See postconf(5) for more details including examples.

content_filter(empty)
              After the message is queued, send the entire message to the specified transport:destination.

       receive_override_options(empty)
              Enable or disable recipient validation, built-in content filtering, or address mapping.

       The  pickup(8)  daemon  waits  for  hints that new mail has been dropped into the maildrop directory, and
       feeds it into the cleanup(8) daemon.  Ill-formatted files are deleted without notifying  the  originator.
       This program expects to be run from the master(8) process manager.

       Problems and transactions are logged to syslogd(8) or postlogd(8).

       The Secure Mailer license must be distributed with this software.

config_directory(see'postconf-d'output)
              The default location of the Postfix main.cf and master.cf configuration files.

       ipc_timeout(3600s)
              The time limit for sending or receiving information over an internal communication channel.

       line_length_limit(2048)
              Upon  input,  long  lines  are  chopped up into pieces of at most this length; upon delivery, long
              lines are reconstructed.

       max_idle(100s)
              The maximum amount of time that an idle Postfix daemon process waits for  an  incoming  connection
              before terminating voluntarily.

       max_use(100)
              The  maximal  number  of  incoming  connections  that a Postfix daemon process will service before
              terminating voluntarily.

       process_id(read-only)
              The process ID of a Postfix command or daemon process.

       process_name(read-only)
              The process name of a Postfix command or daemon process.

       queue_directory(see'postconf-d'output)
              The location of the Postfix top-level queue directory.

       syslog_facility(mail)
              The syslog facility of Postfix logging.

       syslog_name(see'postconf-d'output)
              A prefix that is prepended to the process name in syslog records, so that,  for  example,  "smtpd"
              becomes "prefix/smtpd".

       Available in Postfix 3.3 and later:

       service_name(read-only)
              The master.cf service name of a Postfix daemon process.

       Available in Postfix 3.5 and later:

       info_log_address_format(external)
              The email address form that will be used in non-debug logging (info, warning, etc.).

       The  pickup(8) daemon is moderately security sensitive. It runs with fixed low privilege and can run in a
       chrooted environment.  However, the program reads files from potentially hostile  users.   The  pickup(8)
       daemon  opens  no  files  for  writing,  is  careful  about what files it opens for reading, and does not
       actually touch any data that is sent to its public service endpoint.
