Problem/Motivation

In Drupal 9.2.9 using SMTP version (1.0.0) when I try to connect to Amazon SES and try to programmatically send mail, I get the following error. Sending a SMTP test mail works fine from Drupal admin.

Error log - Error sending e-mail from xxxx to xxx@gmail.com: SMTP Error: data not accepted.SMTP server error: DATA END command failed Detail: Transaction failed: Expected ';', got "\" SMTP code: 554

2022-02-02 06:17:37 CLIENT -> SERVER: X-Mailer: PHPMailer 6.5.3 (https://github.com/PHPMailer/PHPMailer)

2022-02-02 06:17:37 SMTP ERROR: DATA END command failed: 554 Transaction failed: Expected ';', got "\"
SMTP Error: data not accepted.

This is code I am using.

$mail_manager = \Drupal::service('plugin.manager.mail');
$result = $mail_manager->mail($module_name, $key, $recipients, $langcode, $params, $reply, true);

Steps to reproduce

This is the SMTP configuration.

  • SMTP port: 587
  • Use TLS
  • Timeout: 30

Title: Issue in sending SMTP mail via AWS programmatically » Issue in programmatically sending emails via AWS
Project: Drupal core » PHPMailer SMTP
Version: 9.4.x-dev » 2.1.x-dev
Component: mail system » Code

In a plain Drupal installation, the class used to send emails is PhpMail, which uses the mail() function implemented by PHP to send emails, not the PHPMailer library.

It seems you are using the PHPMailer SMTP module.

The code that could cause that issue is in PhpMailerSmtp::mail(), but since it uses trim(), it removes any trailing new line character.

      // Extract Content-Type and charset.
      if (isset($headers['content-type'])) {
        $content_type = explode(';', $headers['content-type']);
        $this->ContentType = trim(array_shift($content_type));
        foreach ($content_type as $param) {
          $param = explode('=', $param, 2);
          $key = trim($param[0]);
          if ($key == 'charset') {
            $this->CharSet = trim($param[1]);
          }
          else {
            $this->ContentType .= '; ' . $key . '=' . trim($param[1]);
          }
        }
        unset($headers['content-type']);
      }

In Drupal 9.2.9 using SMTP version (1.0.0)

I think this is the SMTP Auth module, which also uses the PHPMailer library.

But in response to #4, I don't think the trim() is a problem. The properties are used by the PHPMailer library which adds the appropriate separators or newlines as required.

I misread #4. Ignore my comment #6.
