Spamassassin - 如何获得更好的分数

Spamassassin - 如何获得更好的分数

我正在测试联系表格,但从联系/预订表格发送的电子邮件得分太高了。

以下是标题:

我将上述电子邮件的某些部分替换为 YYYY。我故意发送了一封 GTUBE 测试垃圾邮件,以获得高分,以便在标题中包含详细信息。

我明白那个免费电子邮件回复无法修复 - 因为客户将拥有一个免费的电子邮件地址,而表单将其放在“回复”中。有什么办法可以修复吗?

这些怎么办?可以修复吗?:

*  0.4 NO_DNS_FOR_FROM DNS: Envelope sender has no MX or A DNS records
*  0.1 DKIM_SIGNED Message has a DKIM or DK signature, not necessarily valid
*  0.6 HTML_MIME_NO_HTML_TAG HTML-only message, but there is no HTML ta

邮件服务器和 Web 服务器都设置了 rDNS!因此我无法理解 rDNS x-spam-reports...

如果您能:

  • 更好地解释这些观点
  • 告诉我要检查什么
  • 修复什么/如何修复

提前致谢

答案1

由于您拥有联系表单,因此您只需在 local.cf 中将发件人地址列入白名单即可,方法是

whitelist_from [电子邮件保护]

或者更好的是,

whitelist_from_rcvd [电子邮件保护]yyy.glmr.in

whitelist_from_rcvd还会检查 Received-header,以便垃圾邮件发送者不能伪造发件人地址。

如果您的意思是这样,那么您提到的检查都可以用自定义分数覆盖:

分数 FREEMAIL_FORGED_REPLYTO 0 # 现在将给出 0 分,而不是默认值。

你获得不同状态的原因是

  • FREEMAIL_FORGED_REPLYTO:您的发送地址与回复地址不匹配,而 Google 是免费服务。免费服务意味着更多的垃圾邮件发送者,所以这就是它存在的原因。您只需将邮件中的回复地址发送到[电子邮件保护]以便他们复制/点击回复地址并在那里写下答案。
  • CK_HELO_GENERIC = 已接收:来自 host49-253-177-94.static.arubacloud.com,这通常是您为最终用户(而不是服务器)执行反向 DNS 的方式,尤其是邮件服务器应该具有适当的 PTR。这通常由托管服务提供商中的某个界面设置。
  • NO_DNS_FOR_FROM DNS = 由于您没有 PTR,我猜您也没有设置 MX 来指向您的邮件服务器。这通常也适用于垃圾邮件,因为它们不使用用户服务器,而是使用其他客户端计算机。
  • DKIM_SIGNED = 这就是上面所说的,有一个 DKIM 签名。
  • HTML_MIME_NO_HTML_TAG = 也就是说,这封邮件中只有 HTML 消息,没有 HTML 标签来指定邮件。
