mysql - MIME 电子邮件 - While 循环 - 数据库 - 错误

Question

已解决:安装 PHPMailer 后，它现在可以工作了。

---

我正在尝试使用 MIME 电子邮件向大量成员发送邮件。 看到我的网络主机对某个功能可以在其服务器上运行的时间有限制，我不得不调整旧功能。 这就是我希望它工作的方式:

1. 从数据库表中获取每个成员的电子邮件地址，并使用所有这些电子邮件地址创建一个新表。
2. 在新表中，我还创建了两个名为“已发送”和“错误”的属性。
3. 我打算使用Cron关于这个功能。因此，每一行电子邮件地址最终都将设置为 Sent = True(1) 或 Error = True (1)。

只有一个问题。我尝试在 4 个电子邮件地址上进行测试。当其中之一返回错误时，以下所有电子邮件地址都会出现相同的错误。

错误消息示例:

Error: 501 : malformed address: �> may not follow **Probably caused of ÆØÅ**
Error: 501 : domain missing or malformed  **Because @service.com is missing**

等等..

输出示例:

1: Before function. Error value: 
1: After function. Error value: 501 : domain missing or malformed
2012-10-10 20:07:46 : 1: MemberID: 1, Mail:testme
Error: 501 : domain missing or malformed 

2: Before function. Error value: 
2: After function. Error value: 501 : domain missing or malformed
2012-10-10 20:07:46 : 2: MemberID: 2, Mail:<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="fc88998f889199bc9b919d9590d29f9391" rel="noreferrer noopener nofollow">[email protected]</a>
Error: 501 : domain missing or malformed 

3: Before function. Error value: 
3: After function. Error value: 501 : domain missing or malformed
2012-10-10 20:07:46 : 3: MemberID: 3, Mail:<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="99edfceaedf4fcd9f1f6edf4f8f0f5b7faf6f4" rel="noreferrer noopener nofollow">[email protected]</a>
Error: 501 : domain missing or malformed* 

我不明白为什么会发生这种情况。

Answer 1

您不会在每次发送后清除 $email_message 对象，而是使用相同的 $email_message 对象，只是附加新地址并发送(如果这些地址之一)不正确，您将错误转给以下收件人。

您可以尝试替换以下代码:

$email_message->SetEncodedEmailHeader("To", $to_address, "");

对于这个:

$email_message->ClearAddresses();
$email_message->AddAddress($to_address, $to_address);
