I have been trying to send email for 2 days. using php I have tried different methods but to no avail .
I am sure I am making some small mistake.
Please can someone give step by step procedure of sending mail using Xampp?

The SMTP reply "530 Authentication Required" that saw means the remote server is refusing the message because no authenticated, encrypted SMTP session was used. On XAMPP/Windows the two practical approaches are: 1) configure a sendmail emulator exactly to perform SMTP auth (fragile and platform-specific), or 2) use a proper SMTP client library from PHP so you can authenticate and use TLS. As recommended, libraries like PHPMailer remove most of the guesswork; was right to point you at php.ini settings, but that alone won’t fix providers that insist on authenticated TLS.

Checklist and minimal workflow

  • Make sure PHP’s OpenSSL extension is enabled so TLS can be used.
  • Install a maintained SMTP library (Composer: composer require phpmailer/phpmailer or download PHPMailer).
  • Use SMTP with authentication and TLS/SSL; set the From address to a sensible account (many providers check it).
  • Turn on SMTP debug output while testing so you can see the server’s response.

Minimal PHPMailer example (replace placeholders):

use PHPMailer\PHPMailer\PHPMailer;
require 'vendor/autoload.php';

$mail = new PHPMailer(true);
$mail->SMTPDebug = 2;              // show SMTP dialog while testing
$mail->isSMTP();
$mail->Host = 'smtp.example.com';
$mail->SMTPAuth = true;
$mail->Username = 'smtp-user@example.com';
$mail->Password = 'smtp-password';
$mail->SMTPSecure = 'tls';
$mail->Port = 587;

$mail->setFrom('smtp-user@example.com', 'Sender Name');
$mail->addAddress('recipient@example.com');
$mail->Subject = 'Test';
$mail->Body    = 'Hello';
$mail->send();

Troubleshooting pointers

  • Check the library’s debug output — it shows the exact SMTP rejection. That’s how you find whether it’s auth, TLS, wrong From, or a blocked port.
  • Verify the host/port are reachable (firewall/ISP sometimes blocks 25/465/587). Test from the machine with telnet/openssl if needed.
  • Many providers require app-specific passwords or OAuth2 for SMTP; consult your provider’s current docs.
  • If you must use mail()/sendmail emulation, ensure the emulator actually performs SMTP AUTH and TLS — but know that using a library is simpler and more robust.

Summary: enable OpenSSL, switch to PHPMailer (or similar), authenticate over TLS, and use SMTP debug to read the server’s messages — that will pinpoint the remaining issue.

are my settings correct?

<html>
<body>

<?php
if (isset($_REQUEST['email']))
//if "email" is filled out, send email
  {
  //send email
  $email = $_REQUEST['email'] ;
  $subject = $_REQUEST['subject'] ;
  $message = $_REQUEST['message'] ;
  mail("someone@example.com", "$subject",
  $message, "From:" . $email);
  echo "Thank you for using our mail form";
  }
else
//if "email" is not filled out, display the form
  {
  echo "<form method='post' action='mailform.php'>
  Email: <input name='email' type='text' /><br />
  Subject: <input name='subject' type='text' /><br />
  Message:<br />
  <textarea name='message' rows='15' cols='40'>
  </textarea><br />
  <input type='submit' />
  </form>";
  }
?>

</body>
</html>

And in your php.ini make sure you have these set correctly
[mail function]
SMTP = "my.mailserver.dom" //localhost, gmail, yahoo..
smtp_port = 25
smtp_username = "" <-- If mail server requires a username
smtp_password = "" <-- If mail server requires a password

//Change values
//PHP_INI_ALL
sendmail_from NULL
//PHP_INI_SYSTEM
sendmail_path "/usr/sbin/sendmail -t -i"

Hope this helps

No help yet.Do I require phpmailer class?

Make sure you change
sendmail_from NULL
to
sendmail_from ""

Using PHPMailer would've saved you all this hassle.
