Smtp Configuration for PHP Mail

Setting up PHPMailer with Office365 SMTP

@nitin's code was not working for me, as it was missing 'tls' in the SMTPSecure param.

Here is a working version. I've also added two commented out lines, which you can use in case something is not working.

<?php
require 'vendor/phpmailer/phpmailer/PHPMailerAutoload.php';
$mail = new PHPMailer(true);
$mail->isSMTP();
$mail->Host = 'smtp.office365.com';
$mail->Port       = 587;
$mail->SMTPSecure = 'tls';
$mail->SMTPAuth   = true;
$mail->Username = 'somebody@somewhere.com';
$mail->Password = 'YourPassword';
$mail->SetFrom('somebody@somewhere.com', 'FromEmail');
$mail->addAddress('recipient@domain.com', 'ToEmail');
//$mail->SMTPDebug  = 3;
//$mail->Debugoutput = function($str, $level) {echo "debug level $level; message: $str";}; //$mail->Debugoutput = 'echo';
$mail->IsHTML(true);

$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';

if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Message has been sent';
}

php.ini & SMTP= - how do you pass username & password

PHP mail() command does not support authentication. Your options:

1. PHPMailer- Tutorial
2. PEAR - Tutorial
3. Custom functions - See various solutions in the notes section: http://php.net/manual/en/ref.mail.php

PHPMailer SMTP configuration

Just noticed I typed SMTP wrong in this line $mail->SMPTAuth = true;, correcting this solved my problem.

Use default PHP mail function with SMTP server on Linux

You standard php mail function will just send to whatever is defined as the sendmail _path in php.ini

This is typically sendmail -t -i

You would need to configure sendmail to use smtp.

FWIW, most developer who do a lot of mail sending from PHP apps revile the mail() and instead use one of many mailing libraries (or services) which provide better configurability/reliability.

You could for example pipe the mail function to your own PHP script and use whatever library you wanted to in that script in order to do mail sending (and thus preserving the use of mail() function across applications).
