Thank you it shows that there is no action when I try to move the mail to the Spam directory. Here is the results when I move the mail from the Inbox to the Draft directory  and back to the Inbox :

But when I move the mail to the spam directory, there is nothing in the log.

The original folder was the Inbox. It's a dedicated mail account to test the antispam plugin, so there is no filtering by the client.

Here is my config with the logging enabled :

# 2.1.7: /etc/dovecot/dovecot.conf

mail_debug = yes

  }
  mailbox Junk {

  }

    special_use = \Sent
  }
  mailbox "Sent Messages" {
    special_use = \Sent
  }
  mailbox Trash {
    special_use = \Trash
  }
  prefix = 
}

    mode = 0666
  }

ssl_key = </etc/dovecot/private/dovecot.pem
userdb {
  driver = passwd
}
protocol imap {
  mail_plugins = " mail_log notify antispam"
}

Thank you for your answers.
