To check if SMTP is working, you can use the following steps: First, use telnet to connect to the SMTP server with the command `telnet <smtp-server-address> 25`. Then, send a test email by entering the SMTP commands: `EHLO <your-domain>`, `MAIL FROM:<your-email>`, and `RCPT TO:<recipient-email>`. Finally, look for any error messages returned by the server. If it accepts the email commands without errors, the SMTP server is working properly.
