Hola a todos, apenas me inscribí hoy en el portal de OpenSuse y estoy muy emocionado de comenzar a probar este nuevo sistema operativo (al menos nuevo para mi), anteriormente (como casi todos) usé Winbugs y hace unos meses emigre a Ubuntu, y quise algo con, no se, quizá mas "reto" y emigré a OpenSuse y desde el día de ayer lo tengo instalado (y desde hoy configurado), espero no molestarlos tanto y quisiera saber si hay alguien de habla hispana aquí (sinceramente no lo dudo...). Gracias adelantadas por la ayuda que en un futuro espero me puedan proporcionar :D que tengan un buen día.

Hi to All.

Is possible to use a variable user in the pipe option?

Yeees... that is possible. Though I don't know if it is exactly what you require. "man 8 pipe" will tell you that the pipe deamon expands the localpart of the recipient address (the part left of the "@" character in the recipient address) for the macro ${user}. If that is the information you need, everything works.

...

ie:

procmail unix - n n - - pipe flags=R user=nobody argv=/usr/bin/procmail -t -m /etc/procmailrc ${sender} ${recipient}

in this line change the user=nobody to user=${user}

I wouldn't touch that.

If you deliver to a command via mailbox_command (not a pipe) then this comes to play:

Mailbox delivery can be delegated to an external command specified with the mailbox_command_maps and mailbox_com- mand configuration parameters. The command executes with the privileges of the recipient user (exceptions: sec- ondary groups are not enabled; in case of delivery as root, the command executes with the privileges of default_privs).

Would that help you?

...

it is not exactly to change the procmail user, but for changing the user in the emailto fax gateway, the line is similar.

How does the line look?

Well, the case is exactly this one. I have a mail to fax gateway, but the fax jobs are sent always with the same user (the sendfax). What i want is that the fax job is sent each time with the user who really send the mai Now i have this line in the master.cf fax unix - n n - 1 pipe flags= user=fax argv=/usr/bin/faxmail -d -n $(user) All the faxes seems to be sent by the user fax. I whant that each fax sent belongs to the user who really sent the fax. what i whould change is the user=fax to user=$(user), but i tried this and failed Thanks -- Un saludo.

Have you checked the man pages for faxmail to see what options are available to set the user?

Yes, it is notifying the user passed in $(user) but the job of the fax belongs to the user who call faxmail Well, i will try in the HylaFax list. Thanks -- Un saludo. Carlos Lorenzo Matés. clmates AT mundo-r DOT com

It's worth a try. How would you execute the faxmail on the command line?

I have not tried this, but i found that the with -u parameter you can pass the user i tried -u $(sender) but it uses user@domain and the user must be without the domain part. I'm going to test a bit and perhaps make a little bash script to adapt parameters and call faxmail form this script Thanks again

You might also try the Postfix users list at by sending an mail to <Majordomo@cloud9.net> to subscribe, with the following command in the body of your email message: subscribe postfix-users Regards -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Thanks.

I'm having a lot of feedback in the hylafax list, i'm playing around a few ideas they told me. But i will try in the postfix list if i don't find a good solution

Have you tried to use the command in mailbox_command as I suggested? That would take care of the user rights problem, provided the user is a system user. -- Sandy List replies only please!

I tried with a custom script but i cant find how to get the mail to a variable to pass it to the mailfax command, i get the rest of the parameters, but no idea of how to get the mail itself (it comes form the pipe)

I don't really understand right what you mean with mailbox:command, sorry :-(

http://www.postfix.org/postconf.5.html#mailbox_command This is only available for recipient address in $mydestination. The documentation also lists the variables that can be used in mailbox_command.

the users ara autentified against pam and ldap, but there is not problem, the command is executed as user fax, this is right , but i can pass it a

That is what would be different with mailbox_command. The script is called as the user, that the command is run for.

parameter to set the job owner, the problem is that parameter is not in the proper way in the postfix master.cf.

What i tried to do is call a custom script in the master.cf like that

fax unix - n n - 1 pipe flags= user=fax argv=/usr/local/bin/customfax.sh $(user) $(sender)

then the customfax.sh shoul do

#owner sender owner='cut -f 1 -d @ $sender'

#destination is user destination=$1

faxmail -o $owner -d -n $destination (and here should pass the piped mail)

this is the point i'm stoped in this way

Okay, I finally realized just what you wanted to do. This is a script I adjusted for your purpose. You need to add error handling to your faxmail routine to achieve a robust transport. #----------------------------------------------------- #!/bin/sh # I set this up in /var/lib/filter INSPECT_DIR=/var/lib/filter # Exit codes from <sysexits.h> EX_TEMPFAIL=75 EX_UNAVAILABLE=69 # Clean up when done or when aborting. trap "rm -f in.$$" 0 1 2 3 15 # Start processing. cd $INSPECT_DIR || { echo $INSPECT_DIR does not exist; exit $EX_TEMPFAIL; } cat >in.$$ || { echo Cannot save mail to file; exit $EX_TEMPFAIL; } # Specify your content filter here. # filter <in.$$ || { # echo Message content rejected; exit $EX_UNAVAILABLE; } #owner sender owner=`echo $2|cut -f 1 -d"@"` #destination is the user destination=$1 faxmail -o $owner -d -n $destination <in.$$ exit $? #----------------------------------------------------- -- Sandy List replies only please!

Thank you very much, Sandy, I will try with your script on monday, as i need this in my job.

just to enhance my knowledge, could you explain a bit this sentences please?

cat >in.$$ || { echo Cannot save mail to file; exit $EX_TEMPFAIL; }

I assume this gets the piped mail into "in.PID"

The mail gets piped into the file or if this is not possible the script reports the problem and sets exit code to tempfail and exits.

I need no content filter, as faxmail parses teh mail contents and convers teh multiparts to postscripts

That script is taken from the example of the simple filter script of the postfix documentation. The part with the content filter is commented out to show where the content filter should be called. In your case I would probably check the error code of faxmail and report back to the sender if the fax was sent or not.

faxmail -o $owner -d -n $destination <in.$$

then the way to pass the piped mail is with the < in.$$ saved previously, rigth?

Yes.

how should i call this script form master.cf like i was calling mine?

Exactly as you have shown. Otherwise the script parameters probably would not be $1 and $2. -- Sandy List replies only please!
