PFQUEUE(1)PFQUEUE(1)NAMEpfqueue - A queue realtime scanner for MTA
SYNOPSISpfqueue [-ehvn] [-b postfix1|postfix2|exim] [-q queue#] [-m maxmsg]
[-s seconds] [-l seconds] [-B backends_path] [-p executa‐
bles_path] [-c config_path] [-d seconds]
DESCRIPTIONpfqueue 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 STATUSpfqueue 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
OPTIONSpfqueue accepts the following options, which are common to any backend:
-B backends_path
Tell pfqueue where backends are located. They should be automat‐
ically 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 back‐
end).
-v Show version.
-h Show usage.
-c config
Use a custom MTA configuration; note that the meaning of 'con‐
figuration' 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 run‐
ning 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 ar‐
chive 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 chang‐
ing 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.

HISTORYpfqueue was originally thought as a dedicated Postfix tool, and actu‐
ally 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.
