PHPMailer 如何在 PHP 中发送后将 email 保存在 Outlook 上的已发送项目文件夹中

Question

I am using PHPMailer to send emails notification from our internal stmp server in the company. The emails are sent successfully but not stored in the sent Items folder on Outlook .

<?php

use PHPMailer\PHPMailer\PHPMailer;
use PHPMailer\PHPMailer\SMTP;
use PHPMailer\PHPMailer\Exception;

require 'phpmailer/vendor/autoload.php';


$mail = new PHPMailer(true);

try { 

    $mail->SMTPDebug = SMTP::DEBUG_SERVER;                     
    $mail->isSMTP();                                            
    $mail->Host       = 'smtpinternal.xxxx.com';  
    $mail->SMTPAuth = false;
    $mail->SMTPAutoTLS = false; 
    $mail->Username   = 'xxxxnoreply@xxxx.com';                     
    $mail->Password   = 'xxxx';                               
    $mail->Port       = 25; 
    $mail->setFrom('xxxxnoreply@xxxx.com', 'xxxx_NoReply');

    $distributionLists = explode(',', $items['Distribution List']);
    foreach ($distributionLists as $distributionList) {    
        if (!empty($distributionList) && strpos( $distributionList, '@' ) !== false ) { 
            $mail->addAddress(trim($distributionList)); } 
    }

    $contacts = explode(',', $items['Contact']);
    foreach ($contacts as $contact) {
        if (!empty($contact) && strpos( $contact, '@' ) !== false ) { 
            $mail->addCC(trim($contact)); } 
    }

    $mail->isHTML(true);                                  
    $mail->Subject = 'Invoice Report';
    $mail->Body = "Dear Client, <br><br> Please find below today's invoices <br><br>". $table ."<br> Please contact your representative on Email address : ". $items['Contact'] ."<br><br> Best regards. <br><br> Please do not reply to this message, as it has been sent by a system email address.";
    $mail->send();

  $mail_string = $mail->getSentMIMEMessage();
  $path = "{".$mail->Host.":25/imap/ssl/novalidate-cert}";
  $imapStream = imap_open($path, $mail->Username, $mail->Password);
    imap_append($ImapStream, $path, $mail_string, "\\Seen");



} catch (Exception $e) { 
  echo "Message could not be sent. Mailer Error: {$mail->ErrorInfo}"; }


?>

The imap_open function returns the following error:

imap_open(): Couldn't open stream {smtpinternal.xxxx.com:25/imap/ssl/novalidate-cert}

I tried updating $path to

{"imap.smtpinternal.xxxx.com:25/imap/ssl/novalidate-cert} or {smtpinternal.xxxx.com:25/imap/ssl/authuser=xxxxnoreply@xxxx.com}

But still getting the same error. Any suggestions please how i should declare my path variable to point to Sent Items folder in Outlook ? Thank you.

Answer 1

I'd guess the problem is that you are trying to use IMAP on port 25, which is inbound SMTP's port. You should be using port 143 for IMAP, or 993 if you want TLS encryption on it, which is what the IMAP upload example provided with PHPMailer does.

I can't tell you what IMAP paths to use – you would need to refer to Outlook's docs for more on that.

Answer 2

The latest versions of Exchange (such as those used by Office 365) already save messages sent through SMTP in the user's Sent Items folder.
