How to check mail working from server

To check if mail is working from a server, you can perform the following steps:

Method 1: Using telnet

  1. Open a terminal or command prompt on your local machine.
  2. Type telnet <server_ip> 25 (replace <server_ip> with the IP address of your mail server).
  3. Press Enter. If the connection is successful, you should see a response like 220 <server_name> ESMTP.
  4. Type HELO <your_domain> (replace <your_domain> with your domain name).
  5. Press Enter. If the connection is successful, you should see a response like 250 <server_name> Hello <your_domain>.
  6. Type MAIL FROM:<your_email> (replace <your_email> with your email address).
  7. Press Enter. If the connection is successful, you should see a response like 250 2.1.0 <your_email>... Sender ok.
  8. Type RCPT TO:<recipient_email> (replace <recipient_email> with the email address of the recipient).
  9. Press Enter. If the connection is successful, you should see a response like 250 2.1.5 <recipient_email>... Recipient ok.
  10. Type DATA and press Enter.
  11. Type a simple message, such as This is a test message. and press Enter.
  12. Type . (dot) and press Enter to send the message.
  13. If the message is sent successfully, you should see a response like 250 2.0.0 Message accepted for delivery.

Method 2: Using a mail client

  1. Open a mail client like Microsoft Outlook, Mozilla Thunderbird, or Apple Mail.
  2. Set up a new account using the mail server's settings (e.g., server name, port, username, and password).
  3. Try sending a test email to a recipient's email address.
  4. If the email is sent successfully, it should be delivered to the recipient's inbox.

Method 3: Using a web-based mail client

  1. Access the web-based mail client of your mail server (e.g., Roundcube, SquirrelMail, or Horde).
  2. Log in using your email address and password.
  3. Try sending a test email to a recipient's email address.
  4. If the email is sent successfully, it should be delivered to the recipient's inbox.

Additional steps

  1. Check the mail server's logs to see if there are any errors or issues with the mail delivery.
  2. Verify that the mail server is configured correctly and that the DNS records are set up properly.
  3. Check the recipient's email client or server to see if they are receiving the test email.

By following these steps, you should be able to determine if mail is working from your server.
