Php SMTP服务器响应：451

我已经构建了两个联系人表单（quote.php和contact.php），使用jquery进行验证，并提交给单独的ajax_contact.php和ajax_quote.php文件。它们都是基于我在其他网站上使用的相同模板构建的，但出于某种原因，ajax_contact.php返回以下错误：

Warning: mail() [function.mail]: SMTP server response: 451 See http://pobox.com/~djb/docs/smtplf.html. in D:\Hosting\5219056\html\ajax_contact.php on line 41

我收到的是自动回复邮件，但不是包含表单中提交的数据的邮件

我真的对此束手无策。我一整天都在试图用“\r\n”和“\n”来修复它，我原以为会根据错误来修复它，但我仍然在同一条船上

以下是ajax_contact.php：

    <?php

        // where is your config file stored?
include ("ajaxSubmit.php");

    // CLIENT INFORMATION

不仅在标题中使用，而且在正文中使用\r\n。
由于您使用文件中的换行符，您可以在您使用的代码编辑器中进行设置。
代码中的所有这些
3D
是什么？刚好在$variable之后=

$recipientname =3D "Company";

刚刚看到你的编辑-想朝你的方向扔。它不使用PHP mail（）函数，但如果您在当前设置中使用mail（）函数编写了所有内容，则只需做一些小的更改

看一看，如果你有任何问题，请告诉我

如果不使用任何自定义标题，它是否有效？我尝试过，但可能做得不对。LF应该在正文消息中的每一个换行符之后吗？从服务器对您的回答来看，您需要使用另一个换行符，而不仅仅是LF。试试看\r\n我不知道。我已经有一段时间没问这个了。我甚至不记得我在做什么-/嘿，是的，这是一条很老的线。出于某种原因，它突然出现在头版。无论你在做什么，我想这都是问题所在：-）
