在我的服务器中，我通过 PHP 发送邮件，但我的邮件总是进入垃圾邮件文件夹。我做了 spf 记录的事情，但没关系。我也使用这个域的谷歌应用服务。请帮忙

Hello! This is a simple email message.

域 SPF 记录： v=spf1 ip4:82.25.120.6 ip4:85.25.122.12 包括:_spf.google.com ~all

【解决方案1】：

您是否进行了 DNS 设置以从您的站点发送邮件。如果不这样做，您的邮件接收者将无法识别您，从而将您的邮件发送到垃圾邮件。与您的托管支持人员联系，他们将指导您进行此类 DNS 设置。

    【解决方案2】：

    正如 Erick 所说，您的 SPF 声明为已通过，所以我会，但它归结为您的 php 主函数中的标头格式错误

    这是你的代码：

    <?php
$headers  = "MIME-Version: 1.0\r\n";
$headers .= "Content-type: text/html; charset=iso-8859-1\r\n";
$headers .= "From: UzmanKirala <bilgi@uzmankirala.com>\r\n";

$mail_body = "This<br />is<br />a<br />test<br />mail.";
mail('uzmankirala@hotmail.com', 'Subject', $mail_body, $headers);
?>

    Google 会阅读此内容并发现邮件格式不正确，因为没有边界。缺少正确的新行等。

    我不会费心解释整个 RFC For the Email Formats，而是将您指向一个我一直使用并且运行良好的文件。

    阅读类文件并了解如何充分使用它，但现在这里是一个入门示例：

    $mail = new Mail();

$mail->setTo("mektup@gmail.com");
$mail->setFrom("bilgi@uzmankirala.com");
$mail->setSender("Bilgi");
$mail->setSubject("Test mail");
$mail->setHtml("<b>Some html email</b>");

$mail->send();

    【讨论】：

    • 我试过了，但没有任何改变，邮件进入了垃圾邮件文件夹，但是当我在不同的服务器上尝试相同的代码时它工作了。我认为问题是我的服务器，但是什么？谢谢
    • 你的 IP，必须被列入黑名单，否则 From 电子邮件域可能被列入黑名单，很可能是 IP
    • 这当然解决了我的问题，我也有 SPF 通行证，但被垃圾邮件屏蔽了。谢谢！
    • @RobertPitt 这是解决问题的绝妙方法。它确实有效，无需进一步调整。垃圾邮件过滤器比以往任何时候都更加严格。您构建电子邮件内容的方式也很重要。与纯文本电子邮件相比，使用 Html 更有可能取得成功。尽管如此，Html 电子邮件的编码必须符合特定的编码标准，否则电子邮件可能根本无法送达。
    【解决方案3】：

    首先，要长期解决这个问题，最好的办法就是使用服务来发送电子邮件。有很多，但我听说过这三个的好消息：

    还有一个应该很酷的新进入者http://www.emailyak.com/，但它们仍处于测试阶段。所有服务都非常实惠，具有超级简单的 API，并且可能会立即解决您的问题。

    如果这不是一个选项，或者您只是不想朝那个方向发展，您将需要生成（或让某人发送）垃圾邮件报告，以说明您的邮件为何进入他们的垃圾邮件文件夹。这是我所说的垃圾邮件刺客的一个例子：

    Content analysis details:   (7.9 points, 6.0 required)

pts rule name              description
---- ---------------------- --------------------------------------------------
3.2 FH_DATE_PAST_20XX      The date is grossly in the future.
1.1 DNS_FROM_OPENWHOIS     RBL: Envelope sender listed in bl.open-whois.org.
0.6 SPF_SOFTFAIL           SPF: sender does not match SPF record (softfail)
0.0 UNPARSEABLE_RELAY      Informational: message has unparseable relay lines
1.6 HTML_IMAGE_ONLY_28     BODY: HTML: images with 2400-2800 bytes of words
0.0 HTML_MESSAGE           BODY: HTML included in message
0.0 BAYES_50               BODY: Bayesian spam probability is 40 to 60%
                           [score: 0.5000]
1.5 MIME_HTML_ONLY         BODY: Message only has text/html MIME parts

    获得此信息后，您就可以诊断问题。我怀疑这与您的 SPF 记录有关，但很难肯定，即使它们在标题中被列为“通过”。

    祝你好运！
