— a failed connection to localhost:25 usually means nothing is actually listening on port 25 (or it is bound where your test client cannot reach it). The replies from and point at network/service causes; below are concrete, low-risk checks and options to get a working SMTP endpoint on Windows 7.

Start by confirming whether any process is listening on port 25. Run an elevated command prompt and check listening sockets and the owning executable:

netstat -anob | find ":25"
netstat -ano | find ":25"
tasklist /FI "PID eq <pid-from-netstat>"

If those commands show no listener, the SMTP software was not installed or its service did not start. If a PID is shown, use the tasklist output to identify which program owns it. Also inspect Event Viewer (Windows Logs -> Application/System) for service errors.

Windows 7 does not include a full IIS SMTP server role like Windows Server does, so install a third-party SMTP server for local testing or mail delivery. For development use a lightweight test SMTP (no delivery) such as smtp4dev or Papercut. For a production-capable, free mail server try hMailServer.

If a server is listening but connections still fail, check these specifics: run the netstat commands as Administrator (some flags need elevation); verify the server is bound to the expected IP family (IPv4 127.0.0.1 vs IPv6 ::1); confirm the Windows Firewall rule covers the service or port; and check the SMTP app logs for binding/permission errors. Finally, for sending mail to the internet, modern setups use authenticated submission on port 587 (ISP port blocking of 25 is common).

OK I THINK IF YOU HAVE INSTALLED A THIRD PARTY SMTP SERVER, IS THE FIREWALL CONFIGURED TO ALLOW THE APP ON PORT 25. IF NOT OPEN PORT

OR USE

QK SMTP Server - THE BEST ON WINDOWS (LIGHT WEIGHT)
