plugin antispam sa-learn run program failed with exit code -1

Hello !

I've installed iRedMail on an Ubuntu Server 14.04.1

I'm not the only one on the iRedMail forum to have the problem, but the 
developpers of iRedMail doesn't found the problem and advice me to ask 
you directly.

When I want to move an email directly to /Junk/ this not works.
In Thunderbird, the error is : "[SERVERBUG] failed to send mail"
In RoundCube, the error is : "Server Error: UID MOVE: failed to send mail
."

But, if we firstly delete the email, then move the email from /Trash/ to 
/Junk/ this works.


Here is the package versions:

dovecot 2.2.9-1ubuntu2.1
dovecot-antispam 2.0+20130822-2build1
spamassassin 3.4.0-1ubuntu2.1

I have enabled antispam-debug in syslog, and the sa-learn seems to 
return an error:

I don't known if it's a problem related to dovecot or to spamassassin.
If you could help me to solve the problem, this will be really 
appreciated :)

That looks like it should be three parameters, not two?

- -1 usually means exec() failed, that is:

/usr/bin/sa-learn does not exist or the process thinks so at least.

Do you have SELinux active? http://wiki2.dovecot.org/WhyDoesItNotWork near 
the end.

If this does not help, add a wrapper script in your config and check if 
the script is called at least

Hello Steffen, thanks for your reply.

I've tried to use an external script sa-learn-pipe.sh :

And to update my configuration like that:>

Now, this seems better, no error, the email is correctly moved in /Junk/ 
and I have no error

BUT... the sa-learn-pipe.sh doesn't seems to be called !
No files created in /tmp/

:-(

I also tried to use the "mailtrain" backend but Dovecot doesn't
accept
it ( I suppose I need to set "antispam_backend" to
"mailtrain" but this
doesn't works ).

sestatus doesn't exists, package not installed ( policycoreutils )
and no file /var/log/audit*

So I suppose iRedMail doesn't install SELinux components.

It's not called at all :-/

Hello Andrew, thanks for your answer :)

Sorry about the previous copy/paste, this was a wrong previous test ( 
I've tested to inject others arguments to see if dovecot still report 
the error or no... )

Here is the the same logs :

Ok I'll try to use an external pipe to script

Thanks
