Hello Steffen, thanks for your reply.

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

> #!/bin/bash
> echo /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt echo "$$-start 
> ($*)" >> /tmp/sa-learn-pipe.log
> echo $* > /tmp/sendmail-parms.txt cat<&0 >> /tmp/sendmail-msg-$$.txt
> /usr/bin/sa-learn $* /tmp/sendmail-msg-$$.txt && rm -f 
> /tmp/sendmail-msg-$$.txt &
> echo "$$-end" >> /tmp/sa-learn-pipe.log
> exit 0

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 :-/
