SMTP Error on sending mail - php

Question

I have been trying to send mail using wamp server in my laptop. The SMTP server is presented in online.
Here is my php code to send mail:
<?php
ini_set( 'SMTP', "mail.vickey1192.co.in" );
ini_set( 'smtp_port', 26 );
ini_set( 'sendmail_from', "admin#vickey1192.co.in" );
$to = "balavickey1192#gmail.com";
$subject = "Acknowledgement";
$message = "Thank you for registering with us<br>";
$from = "no-reply#vickey1192.co.in";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
?>
I also set my php.ini file like this:
[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = mail.vickey1192.co.in
; http://php.net/smtp-port
smtp_port = 26
; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = admin#vickey1192.co.in
This is the error I am getting:
Warning: mail() [function.mail]: SMTP server response: 550-Please turn on SMTP
Authentication in your mail client, or login to the 550-IMAP/POP3
server before sending your message. (vignesh-PC)
550-[115.118.170.201]:23328 is not permitted to relay through this
server 550 without authentication. in C:\wamp\www\mailtofunc.php on
line 12
What do I do now? Please help me guys...

I think its a problem with authentication. You need to add the SMTP user's username and password to the mail function to send the email.
//Using built in mail method
$mail = new PHPMailer();
$mail->Host = 'smtp.example.com'
$mail->SMTPAuth = true; // turn on SMTP authentication
$mail->Username = 'your_username#example.com'; // a valid email here
$mail->Password = 'replace_with_your_password';
$mail->From = 'from#example.com';
$mail->AddReplyTo('from#example.com', 'Test');
$mail->FromName = 'Test SMTP';
$mail->AddAddress('test1#example.com', 'test2#example.com');
$mail->Subject = 'Test SMTP';
$mail->Body = 'Hello World';
$mail->Send();
You might be better off trying the PHP's Pear mail function, if you know how to use it.
//Using PEAR's mail function
<?php
include('Mail.php');
/* mail setup recipients, subject etc */
$recipients = "your_recipients#example.com";
$headers["From"] = "user#example.com";
$headers["To"] = "feedback#example.com";
$headers["Subject"] = "Some Subject";
$mailmsg = "Hello, This is a test.";
/* SMTP server name, port, user/passwd */
$smtpinfo["host"] = "smtp.example.com";
$smtpinfo["port"] = "25";
$smtpinfo["auth"] = true;
$smtpinfo["username"] = "smtpusername";
$smtpinfo["password"] = "smtpPassword";
/* Create the mail object using the Mail::factory method */
$mail_object =& Mail::factory("smtp", $smtpinfo);
/* Ok send mail */
$mail_object->send($recipients, $headers, $mailmsg);
?>

Answer 2

Your mail server requires authentication (username + password) before it will accept email from you. It is suggesting you either provide it via your SMTP connection (using SMTP AUTH, hopefully with TLS), or that you do a technique called POP before SMTP where you first login and 'check' your mail which will cause a temporary whitelisting of your host so it can send mail for a brief while afterward.
