NAME

       pfqueue - A queue realtime scanner for MTA

SYNOPSIS

       pfqueue     [-ehvn] [-b postfix1|postfix2|exim] [-q queue#] [-m maxmsg]
       [-s seconds] [-l seconds] [-B backends_path]
       [-p executables_path] [-c config_path] [-d seconds]

DESCRIPTION

       pfqueue is a simple console tool for managing MTA (Mail Transfer Agent)
       message queues. It handles queues through  ’backends’,  libraries  that
       interact  with  the  MTA,  and displays informations through a console,
       ncurses based ’frontend’.
       Currently, pfqueue has backends for Postfix (both 1.x and 2.x) and Exim
       (both version 3 and 4).

EXIT STATUS

       pfqueue returns 0 if everything goes fine, or:

       -1 if pfqueue library cannot be initialized

       -2 if frontend cannot be initialized

       -3 if you are not root

       -4 if pfqueue library cannot be started

OPTIONS

       pfqueue accepts the following options, which are common to any backend:

       -B backends_path
              Tell  pfqueue  where  backends  are  located.  They  should   be
              automatically  found, since your installation should have placed
              them in a standard lib dir. If not so, use this option to  force
              it.

       -b backend
              Load  a  given backend. It can be autodetect, postfix1, postfix2
              or  exim.  Backends  are  libraries  named   pfq_backendname.so,
              located in the installation library path (except for autodetect,
              which is only a virtual backend that will try to guess what kind
              of  MTA  is  installed  on  the  machine, and to load the proper
              backend).

       -v     Show version.

       -h     Show usage.

       -c config
              Use a  custom  MTA  configuration;  note  that  the  meaning  of
              ’configuration’   may   vary:   for  example,  postfix  needs  a
              directory, exim needs a file.

       -m max Set the maximum number of messages shown in a queue. The default
              is 200.

       -s seconds
              Set the display autorefresh rate in seconds. Default is 1.

       -e     Start  reading  from/to  fields from message envelope instead of
              headers, if the backend (and MTA) supports it.

       -p directory
              Set MTA executables path.

       -q queue_num
              Start by scanning the queue number queue_num: 1 for deferred,  2
              for  active,  3 for incoming, 4 for hold, whatever the MTA calls
              them. Some backends may not support all of these queues.

       -l limit
              Make pfqueue limit the time for scanning the queue tree and  for
              retreiving messages informations to this number of seconds; time
              is not that accurate, since blocking I/O  operations  may  cause
              lags,  but it shouldn’t go too far.  Obviously, limiting process
              run time may lead to uncomplete results.  Use this  option  just
              in  case pfqueue takes too long in performing operations, or you
              have a very slow machine, or you have very busy queues.

       -d seconds
              Seconds to wait between queue scans. Default is 1.

       -n     Toggle colors off; note that use of colors can be  toggled  also
              when pfqueue is running, with ’+’ key.

       -r     Remote  host  to  connect  to.  This implies a spfqueue instance
              running on the remote host.

USAGE

       During program run, what you see is a window divided into two sections:
       the  upper  one is the list of messages found in the current queue, and
       the lower one is a small selection of details for the current  message.
       A  number  of  operation  can then be done on a single message, or on a
       bunch of selected messages.

       UP/DOWN arrow keys
              Move the cursor up/down.

       HOME/END or g/G
              Move to the top/bottom of the list.

       1, 2, 3, 4, 5
              Select queue to show. Every MTA handles queues in its  own  way,
              so  these are general keys that cannot be generically described.
              For Postfix, they will select respectively ’deferred’, ’active’,
              ’incoming’,  ’hold’  and  ’corrupt’  queues. For Exim, they will
              have no effect since the backend (and  Exim,  really)  does  not
              archive  messages in different queues depending on their status.

       d      Delete message.

       h      Hold message.

       l      Release message.

       r      Requeue message.

       m      Mark current message: this will "mark" the message as the  start
              of  a  block, and the following ’t’ key (see below) will tag all
              messages between that and the tagged one.

       t      Tag/untag message; tagged messages will be  shown  in  bold.  To
              operate  on  all  the  tagged messages at once, use ’;’ key (see
              below).  If a mark (see above) is present, all messages  between
              the tagged and the marked will be tagged.

       a      Tag all messages.

       u      Untag all messages.

       ;      Make  delete/hold/release/requeue  actions  work  on  all of the
              tagged messages at once.

       :      Toggle auto-work-on-tagged: when activated,  and  if  there  are
              tagged  messages,  actions  will work on tagged indipendently of
              work-on-tagged status (’;’ key).

       e      Toggle reading from/to fields from envelope or headers,  if  the
              backend supports it.

       s      Show current message details.

       /      Find  first  message matching a POSIX regexp; the regexp you use
              can be prefixed by one of f:, t:, e:, s: which  will  limit  the
              search  in,  respectively,  the  From,  To,  From-or-To, Subject
              fields. The default is to search everywhere.

       n      Find next message matching last used regexp.

       p      Find previous message matching last used regexp.

       T      Search and tag messages: all messages matching the  regexp  will
              be  tagged;  the  same  prefixes  described in ’/’ search can be
              used.

       c      Enable/disable confirmation request for action on messages.

       -      Toggle queue scanning on/off.  Use  it  when  you  have  a  fast
              changing  situation  and  you  want  to  freeze  it  for further
              examination. Note that then scanning is disabled,  the  messages
              you  see  in  the  list  may  have gone away (delivered?) in the
              meantime.

       +      Toggle colors on/off.

       >      Increase body window height.

       <      Decrease body window height.

       ,      Scroll body window up.

       b      Show/hide body window.

       .      Scroll body window down.

       B      Toggle body automatic show on/off.

       s      Show body in a new window.

       S      Sort queue by from/to/subject. Keep in mind  that  it  may  slow
              down interface, since the full queue must be read in order to be
              sorted.

       ENTER  Show body of current message (if automatic show is off): if body
              window is not enabled, it behaves like ’s’ key.

HISTORY

       pfqueue  was  originally  thought  as  a  dedicated  Postfix  tool, and
       actually it has been so up to version 0.3.8; since version 0.4.0 it has
       been  extended to use pluggable libraries in order to support virtually
       any kind of MTA.
