    Hi,

     

    Did you configure your email protection in MTA mode? > YES

    Could you please verify if the inbound SMTP traffic is allowed by the correct firewall rule?  >You mean the automatic firewall rule? YES, I have that. I also tried to switch to legacy and switch again to MAT so it will be automatically created but the issue is still there.

     

    Regards,
