Update the local mail routes


Go to (Administration > Configuration > Select the Host Name > Edit > SMTP > Inbound)

  1. Under "Inbound Local Mail Delivery", check the box next to the existing Host/IP Address and then click the Edit button. Change the Host/IP  to the new IP and save.
  2. Also check if there is an Optional Route in (Protocols > Domains > Check the "Domain Name" > Edit > Delivery)
