2 entries are registered on port 7025. It is a registered port (1024–49151) — IANA records an assignee, but nothing stops other software from listening here, which is why the number carries more than one entry.
Port 7025 is primarily used by Zimbra Collaboration Suite's LMTP (Local Mail Transfer Protocol) service for internal mail delivery within the Zimbra server environment. It facilitates the transfer of email messages between the mailbox server and other components handling incoming emails, ensuring reliable and efficient local message distribution.
The registry says what 7025 is registered to. What is listening on it right now is decided by the host, and only the host can be asked. Each of these prints the process behind the socket.
linux
ss -ltnp | grep ':7025\b'
macos
lsof -nP -iTCP:7025 -sTCP:LISTEN
windows
netstat -ano | findstr :7025
On Linux and Windows the process name comes back with the socket; on macOS lsof needs sudo to name a process that isn't yours. Match what it prints against the 2 entries above.
A port number is not a service. Anything may listen on 7025 — what you actually met is decided by the host, not the registry. If a service is missing here, it belongs in the registry.
