Send email using the GMail SMTP server from a PHP page

Question 1

I am trying to send an email via GMail's SMTP server from a PHP page, but I get this error:

authentication failure [SMTP: SMTP server does no support authentication (code: 250, response: mx.google.com at your service, [98.117.99.235] SIZE 35651584 8BITMIME STARTTLS ENHANCEDSTATUSCODES PIPELINING)]

Can anyone help? Here is my code:

<?php
require_once "Mail.php";

$from = "Sandra Sender <sender@example.com>";
$to = "Ramona Recipient <ramona@microsoft.com>";
$subject = "Hi!";
$body = "Hi,nnHow are you?";

$host = "smtp.gmail.com";
$port = "587";
$username = "testtest@gmail.com";
$password = "testtest";

$headers = array ('From' => $from,
  'To' => $to,
  'Subject' => $subject);
$smtp = Mail::factory('smtp',
  array ('host' => $host,
    'port' => $port,
    'auth' => true,
    'username' => $username,
    'password' => $password));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
  echo("<p>" . $mail->getMessage() . "</p>");
 } else {
  echo("<p>Message successfully sent!</p>");
 }
?>

Question 2

// Pear Mail Library
require_once "Mail.php";

$from = '<fromaddress@gmail.com>';
$to = '<toaddress@yahoo.com>';
$subject = 'Hi!';
$body = "Hi,nnHow are you?";

$headers = array(
    'From' => $from,
    'To' => $to,
    'Subject' => $subject
);

$smtp = Mail::factory('smtp', array(
        'host' => 'ssl://smtp.gmail.com',
        'port' => '465',
        'auth' => true,
        'username' => 'johndoe@gmail.com',
        'password' => 'passwordxxx'
    ));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
    echo('<p>' . $mail->getMessage() . '</p>');
} else {
    echo('<p>Message successfully sent!</p>');
}

Question 3

I found my answer. in your Gmail go to

setting ->accounts ->Send mail as

click Add another email address you own in new window enter new email address (example if your gmail is yourmail@gmail.com you must enter your.mail@gmail.com)or(if your gmail address have dot you must change position of dot. example if your gmail is yo.urmail@gmail.com you must enter yourma.il@gmail.com)
don't forget uncheck Treat as an alias.
click next step.

go back to setting ->accounts ->Send mail as
make a new email as defult
check Reply from the same address the message was sent to
all done!
i change code use new codes.

now show from my site

now when you click replay botton show replay to user email

<?php
include "classes/class.phpmailer.php"; // include the class name
$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'tls'; // secure transfer enabled REQUIRED for GMail
$mail->Host = "smtp.gmail.com";
$mail->Port = 587; // or 587
$mail->IsHTML(true);
$mail->Username = "yourmail@gmail.com"; 
$mail->Password = "xxxxxxxxx";
$mail->addReplyTo("useremail@gmail.com","user");
$mail->SetFrom("useremail@gmail.com","My Site");
$mail->Subject = "Your Gmail SMTP Mail";
$mail->Body = "Hi, your first SMTP mail via gmail server has been received.";
$mail->AddAddress("yourmail@gmail.com");
 if(!$mail->Send()){
  echo "Mailer Error: " . $mail->ErrorInfo;
}
else{
    echo "Message has been sent";
}
?>

Question 4

I have shared two different mail methods for your requirement..

First case;

// Pear Mail Library
require_once "Mail.php";

$from = '<from.gmail.com>';
$to = '<to.yahoo.com>';
$subject = 'Hi!';
$body = "Hi,nnHow are you?";

$headers = array(
    'From' => $from,
    'To' => $to,
    'Subject' => $subject
);

$smtp = Mail::factory('smtp', array(
        'host' => 'ssl://smtp.gmail.com',
        'port' => '465',
        'auth' => true,
        'username' => 'johndoe@gmail.com',
        'password' => 'passwordxxx'
    ));

$mail = $smtp->send($to, $headers, $body);

if (PEAR::isError($mail)) {
    echo('<p>' . $mail->getMessage() . '</p>');
} else {
    echo('<p>Message successfully sent!</p>');
}

Second case; (http://ctrlq.org/code/19589-send-mail-php)

$mail = new PHPMailer;

$mail->isSMTP();                                      // Set mailer to use SMTP
$mail->Host = 'smtp.gmail.com';                       // Specify main and backup server
$mail->SMTPAuth = true;                               // Enable SMTP authentication
$mail->Username = 'amit@gmail.com';                   // SMTP username
$mail->Password = 'digitalinspiration';               // SMTP password
$mail->SMTPSecure = 'tls';                            // Enable encryption, 'ssl' also accepted
$mail->Port = 587;                                    //Set the SMTP port number - 587 for authenticated TLS
$mail->setFrom('amit@gmail.com', 'Amit Agarwal');     //Set who the message is to be sent from
$mail->addReplyTo('labnol@gmail.com', 'First Last');  //Set an alternative reply-to address
$mail->addAddress('josh@example.net', 'Josh Adams');  // Add a recipient
$mail->addAddress('ellen@example.com');               // Name is optional
$mail->addCC('cc@example.com');
$mail->addBCC('bcc@example.com');
$mail->WordWrap = 50;                                 // Set word wrap to 50 characters
$mail->addAttachment('/usr/labnol/file.doc');         // Add attachments
$mail->addAttachment('/images/image.jpg', 'new.jpg'); // Optional name
$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';

//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__));

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

echo 'Message has been sent';

Try it and hope it will solve your issues !

Question 5

Man, you read single line replies where there are multiple lines.

MULTILINE REPLY:

250-LINE #1 // lines that have - after ### continue on the next
250-LINE #2 // lines that have - after ### continue on the next
250 LINE #3 // last line has space after ###

SINGLELINE REPLIES:

220 LINE #1 // one reply with code 220
250 LINE #2 // another reply with code 250
// no ### code is followed by - as that means: not the last line!

Your commands are out of sync. So fix like this:

if($smtpLog['hello'] = fgets( $smtpConn )){
    // handle multiline reply
    while($smtpLog['hello']{4} !== ' '){
        $smtpLog['hello'] .= PHP_EOL.fgets( $smtpConn );
    }
}

This applies to every response you get but in your case, commands break sync at EHLO.

Question 6

The code below will send a custom email to customer for a specific product category when order status is changed to "completed":

// On order completed status
add_action('woocommerce_order_status_completed', 'send_a_custom_email', 20, 1 );
function send_a_custom_email( $order_id ) {
    $order = wc_get_order( $order_id ); // The WC_Order object

    foreach ( $order->get_items() as $item_id => $item ) {
        $product = $item->get_product(); // The WC_Product object

        // Get the parent product ID for product variations for product categories
        $the_id = $product->is_type('variation') ? $product->get_parent_id() : $product->get_id();

        if (  has_term( array( 630 ), 'product_cat', $the_id ) ) {
            $to_email = $order->get_billing_email(); // To customer
            $subject = "Your subject goes here";
            $message = "Your message goes here";
            $headers = 'From: Shop Name <shop@email.com>' . "rn"; // From admin email

            wp_mail( $to_email, $subject, $message, $headers ); // Send email
            break; // Stop the loop
        }
    }
}

Code goes in functions.php file of your active child theme (or active theme). Tested and works
