我正在尝试阻止来自一个发件人的垃圾邮件。他们每次都使用另一个邮件服务器。以下是原始电子邮件的标题（我将我的电子邮件和主机替换为：[电子邮件保护]，发件人电子邮件和主机我替换为：[电子邮件保护]，其他保持不变）：

我编辑了/etc/postfix/sender_access拒绝来自 的电子邮件sender-website.com。但这不起作用，因为 postfix 发现电子邮件来自不同的发件人/服务器。来自 postfix 日志文件：

因此，当我在 thunderbird 中查看消息源时，我看到标头：。我如何阻止来自该发件人 (sender-website.com) 的电子邮件？阻止 IP 毫无意义，因为下次会有所不同。我也设置了 MailScanner，但它也看不到正确的标头。我已经在 MailScanner 中将该域列入黑名单。From: Blah blah blah <[email protected]>from
答案1
所以您已将其添加[email protected] REJECT到您的sender_access文件中，您是否已将其添加hash:/etc/postfix/sender_access到您的smtpd_recipient_restrictions =第一个选项中？
使用该选项您可能也会有更好的运气smtp_nested_header_checks，因为它允许您检查任何非 MIME 标头中的标识符。
答案2
重要的提示：
带有规则的 Postfix 文件：
/etc/postfix/sender_access
接受仅限域名（example.com），不是个人电子邮件地址（[电子邮件保护]）互联网上有一些“指南”，暗示它适用于两者，但它没有。
作品：
microsoft.com REJECT
google.com DISCARD
不起作用：
[email protected] REJECT
[email protected] DISCARD
这就是它对某些人“不起作用”的原因。Postfix 文档中也没有明确说明这一点，也没有任何错误。
