       postqueue [-c config_dir] -f
       postqueue [-c config_dir] -p
       postqueue [-c config_dir] -s site


       The  postqueue  program implements the Postfix user inter­
       face for queue management. It implements  operations  that
       are  traditionally  available via the sendmail(1) command.
       See the postsuper(1) command  for  queue  operations  that
       require  super-user  privileges such as deleting a message
       from the queue or changing the status of a message.

       The following options are recognized:

       -c config_dir
              The main.cf configuration  file  is  in  the  named
              directory  instead  of  the  default  configuration
              directory. See  also  the  MAIL_CONFIG  environment
              setting below.

       -f     Flush  the  queue:  attempt  to  deliver all queued

              This option implements the traditional sendmail  -q
              command,  by contacting the Postfix qmgr(8) daemon.

       -p     Produce a traditional sendmail-style queue listing.
              This  option  implements the traditional mailq com­
              mand, by contacting the Postfix showq(8) daemon.

              Each queue entry shows the queue file  ID,  message
              size, arrival time, sender, and the recipients that
              still need to be delivered.  If mail could  not  be
              delivered  upon  the  last  attempt, the reason for
              failure is shown. This mode of operation is  imple­
              mented  by  executing the postqueue(1) command. The
              queue ID string is followed by an  optional  status

              *      The message is in the active queue, i.e. the
                     message is selected for delivery.

              !      The message is in the hold  queue,  i.e.  no
                     further  delivery attempt will be made until
                     the mail is taken off hold.

       -s site
              Schedule immediate delivery of  all  mail  that  is
              queued  for the named site. The site must be eligi­
              ble for the "fast flush" service.  See flush(8) for
              more information about the "fast flush" service.

       Problems  are  logged  to  syslogd(8)  and to the standard
       error stream.


              Directory with the main.cf file.

              In order to  avoid  exploitation  of  set-group  ID
              privileges, it is not possible to specify arbitrary
              directory names.

              A non-standard directory is  allowed  only  if  the
              name is listed in the standard main.cf file, in the
              alternate_config_directories configuration  parame­
              ter value.

              Only  the superuser is allowed to specify arbitrary
              directory names.

              List of names of environment parameters that can be
              imported from non-Postfix processes.

              Top-level  directory  of the Postfix queue. This is
              also the root directory of Postfix daemons that run

              List of domains that will receive "fast flush" ser­
              vice (default: all  domains  that  this  system  is
              willing  to relay mail to). This list specifies the
              domains that  Postfix  accepts  in  the  SMTP  ETRN
              request and in the sendmail -qR command.
