如何在 Symfony 中使用 swiftmailer 使我的电子邮件用户名符合 RFC 2822?

How can I make my email username comply with RFC 2822 using swiftmailer in Symfony?

我尝试在 services.yaml

中为 swiftmailer 设置电子邮件配置
parameters:
    mailer:
        smtp_host: 'abc123.webthing.myhost.de'
        smtp_port: 587
        smtp_cert: 'tls'
        smtp_username: 'ab12345-laura'
        smtp_password: 'secret'

这是邮件服务:

<?php

/**
 * Service that can be used to send email using basic swift mailer transport
 */

namespace App\Service;

use Symfony\Component\DependencyInjection\ParameterBag\ParameterBagInterface;

class Mailer
{
    /**
    * @var array $emailConfig
    */
    private $emailConfig;

    /**
     * Mailer constructor
     *
     * @param ParameterBagInterface $params
     */
    public function __construct(ParameterBagInterface $params)
    {
        $this->emailConfig = $params->get('mailer');
    }

    public function sendMail(array $mailInfo, string $html, array $files = [])
    {
        $emailConfig = $this->emailConfig;

        $smtpHost   = $emailConfig['smtp_host'];
        $smtpPort   = $emailConfig['smtp_port'];
        $smtpCert   = $emailConfig['smtp_cert'];
        $smtpUsername   = $emailConfig['smtp_username'];
        $smtpPassword   = $emailConfig['smtp_password'];

        $transport = (new \Swift_SmtpTransport($smtpHost, $smtpPort, $smtpCert))
            ->setUsername($smtpUsername)
            ->setPassword($smtpPassword)
        ;

        $swiftMailer = new \Swift_Mailer($transport);

        $message = (new \Swift_Message($mailInfo['title']))
            ->setFrom([$smtpUsername => $mailInfo['senderName']])
            ->setTo($mailInfo['sendTo'])
            ->setBody($html, 'text/html');

        foreach ($files as $file) {
            $message->attach(\Swift_Attachment::fromPath($file));
        }

        $swiftMailer->send($message);
    }
}

我测试了这样的代码:

  /**
  * @Route("/_mailer", name="mailer", methods={"GET","POST"})
  */

  public function mailer(MailGenerator $mailGenerator, Request $request) {
    $output = $mailGenerator->sendMail();
    return $output;
  }

我收到错误消息:

Address in mailbox given [ab12345-laura] does not comply with RFC 2822, 3.6.2.

问题出在这里:

setFrom([$smtpUsername => $mailInfo['senderName']])

这需要发送邮件的人的电子邮件地址及其显示名称。您使用 $smtpUsername 作为电子邮件地址,但 ab12345-laura 不是电子邮件地址。

你需要这样的东西:

setFrom(["laura@mail.test" => "Laura Something"])

因此,您的 $mailInfo 不仅应包含姓名,还应包含用于发件人的电子邮件地址,然后使用

setFrom([$mailInfo['senderEMail'] => $mailInfo['senderName']])

问题可能出在这段代码上:

    $message = (new \Swift_Message($mailInfo['title']))
        ->setFrom([$smtpUsername => $mailInfo['senderName']])
        ->setTo($mailInfo['sendTo'])
        ->setBody($html, 'text/html');

它试图将发件人 地址 设置为 ab12345-laura,根据 RFC,这很明显不是有效的发件人地址,因为它缺少 @domain 部分
