Could set spamassassin reject spam mail?

    Hello,
    I have found spamassassin plugins config.php at /var/www/imscp/gui/plugins/SpamAssassin/config.php
    In this file.
    It's have reject_spam and default is set no.
    Could I set it yes and restart spamassassin?Is it will reject spam mail?

    Set to yes, go to admin panel and update the plugin list.
