Smtp server check email delivery

To check email delivery using an SMTP server, you can follow these steps:

Step 1: Set up your email client

• Choose an email client that supports SMTP, such as Microsoft Outlook, Mozilla Thunderbird, or a web-based email client like Gmail.
• Configure your email client to use the SMTP server of your choice. You can usually find this information in your email provider's settings or documentation.

Step 2: Send an email

• Compose an email using your email client and send it to a recipient's email address.
• Make sure to use a valid email address and a subject line.

Step 3: Check the email delivery

• Wait for a few minutes to allow the email to be delivered.
• Check your email client's "Sent Items" or "Outbox" folder to see if the email has been sent successfully.
• If the email is not in the "Sent Items" folder, it may be stuck in the outbox or not sent at all.

Step 4: Check the email server logs

• If you're using a self-hosted email server, you can check the server logs to see if the email was delivered successfully.
• Look for log entries that indicate the email was received and processed by the server.

Step 5: Check the recipient's email client

• Ask the recipient to check their email client for the delivered email.
• If the email is not delivered, check the recipient's email client's "Spam" or "Junk" folder to see if it was filtered out.

Common issues and troubleshooting steps

• Email not sent: Check your email client's settings, ensure you have a valid email address and password, and try sending the email again.
• Email stuck in outbox: Check your email client's settings, ensure you have a valid email address and password, and try sending the email again.
• Email not delivered: Check the email server logs, ensure the email was sent correctly, and try sending the email again.
• Email filtered out: Check the recipient's email client's settings, ensure the email is not blocked by a spam filter, and try sending the email again.

SMTP server commands

• HELO/EHLO: Establish a connection with the SMTP server.
• MAIL FROM: Specify the sender's email address.
• RCPT TO: Specify the recipient's email address.
• DATA: Send the email message.
• QUIT: Close the connection with the SMTP server.

SMTP server responses

• 250: The email was sent successfully.
• 550: The email was not sent due to a recipient's email address not found.
• 421: The email was not sent due to a temporary error.
• 554: The email was not sent due to a permanent error.

By following these steps, you can check email delivery using an SMTP server and troubleshoot any issues that may arise.
