Hybrid mail flow with IronPort
Thanks for your response - I agree that there shouldn't be any device and I am trying to figure out a way to bypass Ironport, but unable to do so.
Is there a way by which I can bypass Ironport considering that traffic on firewall for port 25 is NATed to go to Ironport first. How do I bifurcate the traffic ?

Is not advised by Microsoft to have any device between Exchange and Office 365, but you can setup hybrid and change de Connectors, both on-premises and Online to point to your infrastructure, but for best security you must enable TLS on those devices and Exchange Online and OnPremises Connectors.
akashg88 please have a look at the following post from Cisco

Could that help you solve your issue ?
Kind regards
