faxspool - queue and convert files for faxing with sendfax(8)
Queue the named files for later transmission with
The input files are converted to G3 fax files, spooled to
/var/spool/fax/outgoing/<dir>/f*.g3, and queued for transmsssion to the
fax address "phone-number".
On top of each page,
puts a header line, telling the other
side the number of pages, your fax id, ..., whatever you like. The
format of this line is configurable via the file
(you can select another one with the "-h" option, for example, one for
your business faxes and one for the private stuff).
This file should contain a few lines of text, normally only one line,
but more than one line is permitted. The text may use the tokens
@T@ for the remote telephone number, @U@ for the sending user
name, @N@ for his full name (fifth field of /etc/passwd, if not given
with "-F"), @P@ for the page number and @M@ for the total number of
pages. @D@ will be replaced by the string specified with the "-D"
option (see below), @DATE@ will be substituted by the output of the
`date` command, and @ID@ stands for the sender's fax number
If "phone-number" contains non-numeric characters,
interprets it as an alias and tries to look it up in the files
These files have a very simple format: one line per alias, alias name
first, whitespace (tab or blank), phone number. Optionally, you can place
a short description of the receiver after the phone number, this will be
used as if it had been specified with "-D" (an explicit "-D" flag
Example: gert 0893244814 Gert Doering
Access control is handled similar to the way "crontab" does it: if a file
/etc/mgetty+sendfax/fax.allow exists, only those users listed
in that file (one name per line) may use the fax service. If it does not
exist, but a file /etc/mgetty+sendfax/fax.deny exists, all users
but those listed in that file may use faxspool(1), and if neither file
exists, only root may send faxes. (Note: if the user name in the
fax.allow file is followed by a blank, the rest of that line is
ignored. Some other fax spooling software uses this to store
additional information about the user sending the request).
can generate user-customizable fax cover pages. It is quite easy to set
up: if a file /etc/mgetty+sendfax/make.coverpg exists and is executable, it is run
with all relevant source/destination data on the command line, and its
output is sent as the first page of the resulting fax. See coverpg(1) for
to use normal resolution (as opposed to the default, fine resolution) both
when converting files to G3 format and when transmitting (no effect on pbm
-h <text file>
for the FAX header line(s). The default format file for
/etc/mgetty+sendfax/faxheader. '-' means 'no header line'.
do not output progress messages (file ... is format ..., spooling to ...).
Error messages will be seen anyway.
-f <mail address>
Use the address given for the status mail that faxrunq(1) sends after
completing / dequeueing the request. If no mail address is specified,
the requesting user (on the local machine) gets the mail.
-u <user name>
Do not use the current user ID for authentication purposes but the
user name specified. Since this can lead to easy breach of security,
only "trusted" users may use this flag. Currently, those users are
"root", "lp" and "daemon" (hardwired into the code). Note: the status mail
will still go to the user running faxspool(1) unless changed with "-f".
Verbose form of the fax's destination. Used only for informational
purposes, that is, faxq(1) will show it, faxrunq(1) will put it
into the return mail ("Subject: your fax to ..."), and a @D@ in the
page header will be replaced by it.
Full name or similar description of the sending user (if not specified,
the full name field from /etc/passwd will be used). Used only for
informational purposes, that is, faxspool(1) will substitute a @N@ in the
page header file with it, and it will be passed to the cover page program
(if used) as <sender-NAME>.
Sets the priority of the fax in the queue. 9 is highest (meaning: faxes
get sent out first), 1 is lowest. If nothing is specified, a default
value of 5 is used. Right now, only
will silently ignore it.
-C <cover page program>
Specify that the named program is to be used to generate a cover page for
the fax that is being queued. How the program is called is described in the
The special program name "-" is used to specify "no coverpage at all".
No message is issued if the program isn't found, or cannot be executed,
faxspool will simply queue the fax without cover page.
The default cover page program used is /usr/lib/mgetty+sendfax/make.coverpg.
Spool a request that will try polling (see "sendfax -p"). The
implementation isn't too smart yet, the polled files will simply go
into the job's spool directory.
Don't send the fax before the time given. It may not be sent exactly at
<hh:mm>, but the first time
runs after that time. If the fax cannot be sent successfully before
midnight, it won't be sent on the next day until <hh:mm>!
pass faxspool a chunk of data that is ignored (so you can put anything you
want here), but written to all the log files (acct.log, sendfax.log).
This can be used to tag faxes as private/corporate, to tag faxes with
the customer ID to use for billing, or something along that lines.
-m <phone1> <phone2> <phone3> ... --
Multicasting - send the specified files to all phone numbers in the
list given after "-m". The list is terminated with "--". "-m" has to
be the last option on the command line.
-M <file name>
Multicasting - read a list of telephone numbers to send the fax to
from the given file. Do not use in conjunction with "-m".
Copy source files to a sub directory ".source-files/" in the fax queue
directory (most likely, you won't ever need this - I needed it for one
project, so it's here and documented. Don't ask what it's good for).

the input files.
Multicasting with the -m and -M options is not implemented yet.
