after updating to SFOS 17.0.0 GA we can't able to receive mail from many domain

hi, after updating to SFOS 17.0.0 GA, mails received from some domains received by specific SMTP servers do not arrive and are not even seen in the "Mail Logs" 


after several tests, I have verified that the same email sent at the same time as a gmail.com address arrives correctly

while investigating through the detailed log the mail is viewed on the firewall as invalid traffic


with version SFOS 16.05.8 MR-8 the same mails are received without any problems
