Why procmail is not executed ? Is there some priority or dependencies

Yes: the mail has to be delivered to a mailbox.
You are delivering mail to spamassassin.
You confused me : spamassassin leaves the messages for local delivery
via /usr/local/sbin/sendmail -i "$@"
Yes, I did.
However, you did not provide your entire flow setup, so it was not
completely transparent to me that you were using spamassassin as a
content_filter.
You did show logs that show spamassassin is processing the mail, but I
never saw the config for re-injection, so there was no reason to suppose
that procmail was ever getting hit.
And indeed everything works fine except the missing filtering via
Procmail.
(note : I'm using virtual users).
I know, that's why it doesn't work.
Virtual mailboxes can not run commands, as I already indicated.
More generally, is mailbox_command mandatory ?
No, it's not mandatory.
It is empty by default.
Can I replace it using in master.cf a syntax like following :
smtp inet n - n - - smtpd -o content_filter=procmail:filter
where procmail service will call, via shell script, spamassassing
before doing its filtering, and do I can avoid the need of
mailbox_command.
No, procmail is not a "service".
You have to create one and then deliver to it:
myprocmail unix - n n - - - pipe user=your.virtual.user argv=procmail
- -a $RECIPIENT -a $EXTENSION [-a $MORE_VARS...]
And then either set the virtual_transport to myprocmail or use
transport_maps for more granular control.
NOTE that procmail MUST deliver the message in this case!
If the message "falls out the bottom" of your recipe, it's GORN.

Thanks for your help. It works now.
Indeed virtual_transport need to be setup, not mailbox_command as
virtual users are used in my Postfix setup.
in main.cf :
...
virtual_transport=myprocmail
...
in master.cf :
...
smtp inet n - - - - smtpd
-o content_filter=spamfilter:dummy
spamfilter unix - n n - - pipe
flags=Rq user=spamfilter argv=/usr/local/bin/spamfilter.sh -f
${sender} -- ${recipient}
myprocmail unix - n n - - pipe
flags=DRX user=spamfilter argv=/usr/bin/procmail ... temporary :
other procmail params still need to be fixed here ...
...
Bye,
Bruno
