How to specify the SMTP server in PHPMailer? - php

Question

I want to know how do I get a SMTP server to use PHPMailer to send automatic emails with my created email (email#mydomain.com).
My webhost doesn't provide one. I brought my domain in OnlyDomains and my webhost is 000Webhost.
<?php
require './PHPMailer-master/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = ''; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'noreply#mydomain.com'; // SMTP username
$mail->Password = '********'; // SMTP password
$mail->SMTPSecure = 'tls';
$mail->From = 'noreply#mydomain.com';
$mail->FromName = 'Admin';
$mail->addAddress('sdfsdf#hotmail.com'); // Name is optional
$mail->WordWrap = 50; // Set word wrap to 50 characters
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'swag';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}
?>

You should see if your web host allows you to use sendmail on their system. STMP is not needed with sendmail. Chances are they do since it is a standard part of most any Linux/Unix setup. And since you say that your web host is 000WebHost it seems like they do support the use of sendmail:
You can use PHP's mail() function to send mail for your visitors…
But they also seem to offer SMTP in their premium package.
Past that, I would recommend not worrying about SMTP & sticking to sendmail for now. Looking at the documentation for PHPMailer it seems that the library can use sendmail:
The PHP mail() function usually sends via a local mail server,
typically fronted by a sendmail binary on Linux, BSD and OS X
platforms, however, Windows usually doesn't include a local mail
server; PHPMailer's integrated SMTP implementation allows email
sending on Windows platforms without a local mail server.
Then looking in the examples/ folder in the PHPMailer repository shows there is a sendmail example:
require '../PHPMailerAutoload.php';
//Create a new PHPMailer instance
$mail = new PHPMailer();
// Set PHPMailer to use the sendmail transport
$mail->isSendmail();
//Set who the message is to be sent from
$mail->setFrom('from#example.com', 'First Last');
//Set an alternative reply-to address
$mail->addReplyTo('replyto#example.com', 'First Last');
//Set who the message is to be sent to
$mail->addAddress('whoto#example.com', 'John Doe');
//Set the subject line
$mail->Subject = 'PHPMailer sendmail test';
//Read an HTML message body from an external file, convert referenced images to embedded,
//convert HTML into a basic plain-text alternative body
$mail->msgHTML(file_get_contents('contents.html'), dirname(__FILE__));
//Replace the plain text body with one created manually
$mail->AltBody = 'This is a plain-text message body';
//Attach an image file
$mail->addAttachment('images/phpmailer_mini.png');
//send the message, check for errors
if (!$mail->send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
