    Hi  

    Thank you for reaching out to the Community! 

    Did you configure your email protection in MTA mode? Could you please verify if the inbound SMTP traffic is allowed by the correct firewall rule? 

    Thanks,

    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,
