Debug php mail box

The joys of debugging PHP mail issues!

Here are some common issues and solutions to help you debug your PHP mail box:

1. Check the PHP mail function

Make sure that the PHP mail function is enabled and configured correctly. You can check this by running the following code:

<?php
if (!function_exists('mail')) {
    echo 'The mail function is not available.';
} else {
    echo 'The mail function is available.';
}
?>

If the mail function is not available, you may need to enable it in your PHP configuration file (php.ini).

2. Verify the mail server settings

Check your mail server settings to ensure that they are correct. You can do this by:

• Checking the mail server's hostname and port number
• Verifying the mail server's username and password (if required)
• Ensuring that the mail server is configured to allow outgoing mail

3. Check the mail headers

Use a tool like mailhog or mailcatcher to capture and inspect the mail headers. This can help you identify any issues with the mail headers, such as:

• Missing or incorrect From or To headers
• Incorrect Subject header
• Missing or incorrect Content-Type header

4. Check the mail body

Verify that the mail body is being sent correctly. You can do this by:

• Checking the mail body for any errors or corruption
• Verifying that the mail body contains the expected content

5. Check the PHP error logs

7. Test the mail function

Use a tool like mail-tester or sendmail to test the mail function. This can help you identify any issues with the mail function, such as:

8. Check the PHP version

Make sure that you are using a compatible version of PHP. Some PHP versions may have issues with the mail function.
