Information about the ports used by EngageOne Delivery Audit Web services to communicate to Mail360 Hub


 
The EngageOne Delivery Audit Web services running on the Application Server will need direct outbound access to the following ports of Mail360 Hub
  1. mail360hub.g1.com:8877
  2. mail360hub.g1.com:8878
  3. mail360hub.g1.com:8879
  4. mail360hub.g1.com:8880
Therefore, machine on which EngageOne Delivery Audit Service are hosted should be able to connect to Mail360 Hub on these ports to exchange status information and receive USPS® event data. This communication occurs via SOAP over HTTP, using message-level security. All connections are initiated from the EngageOne Delivery Audit Application Server and no inbound connections are required.
