Via one of my colleagues I received a pretty nice site with an overview of all ports used for communication between the Exchange 2007 server roles. Below the overview:
| Data path | Required ports |
| Hub Transport server to Hub Transport server | 25/TCP (Secure Sockets Layer [SSL]), 587/TCP (SSL) |
| Hub Transport server to Edge Transport server | 25/TCP (SSL) |
| Edge Transport server to Hub Transport server | 25/TCP (SSL) |
| Edge Transport server to Edge Transport server | 25/TCP (SSL), 389/TCP/UDP, and 80/TCP (certificate authentication) |
| Mailbox server to Hub Transport server via the Microsoft Exchange Mail Submission Service | 135/TCP (RPC) |
| Hub Transport to Mailbox server via MAPI | 135/TCP (RPC) |
| Microsoft Exchange EdgeSync service | 50636/TCP (SSL), 50389/TCP (No SSL) |
