Sending Email with PHP from an SMTP Server

Sending Email with PHP from an SMTP Server : #

$from = “someonelse@example.com”;
$headers = “From:” . $from;
echo mail (“borutflis1@gmail.com” ,”testmailfunction” , “Oj”,$headers);
I have trouble sending email in PHP. I get an error: SMTP server response: 530 SMTP authentication is required.

I was under the impression that you can send email without SMTP to verify. I know that this mail will propably get filtered out, but that doesn’t matter right now.

[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = localhost
; http://php.net/smtp-port
smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
sendmail_from = someonelse@example.com
This is the setup in the php.ini file. How should I set up SMTP? Are there any SMTP servers that require no verification or must I setup a server myself?

Here is Some Solutions :

Solution 1: #

$mail = new PHPMailer();

// Settings
$mail->IsSMTP();
$mail->CharSet = ‘UTF-8’;

$mail->Host = “mail.example.com”; // SMTP server example
$mail->SMTPDebug = 0; // enables SMTP debug information (for testing)
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Port = 25; // set the SMTP port for the GMAIL server
$mail->Username = “username”; // SMTP account username example
$mail->Password = “password”; // SMTP account password example

// Content
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = ‘Here is the subject’;
$mail->Body = ‘This is the HTML message body <b>in bold!</b>’;
$mail->AltBody = ‘This is the body in plain text for non-HTML mail clients’;

$mail->send();

Solution 2: #

<?php
ini_set(“SMTP”, “aspmx.l.google.com”);
ini_set(“sendmail_from”, “YOURMAIL@gmail.com”);

$message = “The mail message was sent with the following mail setting:\r\nSMTP = aspmx.l.google.com\r\nsmtp_port = 25\r\nsendmail_from = YourMail@address.com”;

$headers = “From: YOURMAIL@gmail.com”;

mail(“Sending@provider.com”, “Testing”, $message, $headers);
echo “Check your email now….&lt;BR/>”;
?>

Solution 3: #

<?php
$a1 = [‘monday@gmail.com’];
$r1 = fopen(‘a.txt’, ‘r’);
$r2 = curl_init(‘smtps://smtp.gmail.com’);
curl_setopt($r2, CURLOPT_MAIL_RCPT, $a1);
curl_setopt($r2, CURLOPT_NETRC, true);
curl_setopt($r2, CURLOPT_READDATA, $r1);
curl_setopt($r2, CURLOPT_UPLOAD, true);
curl_exec($r2);
