Anti-Spam blade sends Non-Delivery Report (NDR)

Good day! I want to turn off Non-Delivery Report (NDR) according to sk110813. I added mta_spam_action=discard in section [mta]. Unfortunately, it doesn't work. CheckPoint Firewall sents NDR. In my enviroment software of firewall is R77.30 with installed hostfix Take 302.How can I turn off NDR?

Did you get and apply the hotfix from TAC as specified in the SK?

Without that hotfix, the mta_spam_action=discard option won't work. 

If you did apply the hotfix and it doesn't work, please re-engage with the TAC.
