How to test smtp send mail

Testing SMTP (Simple Mail Transfer Protocol) to send mail involves verifying that your email server or application can successfully send emails to a recipient's email address. Here are some steps to test SMTP send mail:

Method 1: Using Telnet

  1. Open a command prompt or terminal window.
  2. Type telnet <SMTP_server> <SMTP_port> and press Enter. Replace <SMTP_server> with your email server's hostname or IP address, and <SMTP_port> with the SMTP port number (usually 25).
  3. Once connected, type HELO <your_hostname> and press Enter. Replace <your_hostname> with your hostname or a fake one.
  4. Type MAIL FROM:<your_email> and press Enter. Replace <your_email> with the email address you want to send from.
  5. Type RCPT TO:<recipient_email> and press Enter. Replace <recipient_email> with the email address you want to send to.
  6. Type DATA and press Enter.
  7. Type the email message and press Enter.
  8. Type QUIT and press Enter to disconnect.

Method 2: Using a Mail Client

  1. Open a mail client like Microsoft Outlook, Mozilla Thunderbird, or Apple Mail.
  2. Create a new email message and set the "From" address to the email address you want to send from.
  3. Set the "To" address to the email address you want to send to.
  4. Write a test message in the email body.
  5. Click the "Send" button to send the email.

Method 3: Using a SMTP Testing Tool

  1. Use a online SMTP testing tool like Mailinator, Sendmail, or SMTP Test Tool.
  2. Enter the email address you want to send from and the email address you want to send to.
  3. Enter the test message and click the "Send" button.
  4. The tool will send the email and provide a report on the success or failure of the send.
