我正试图阻止来自一个发件人的垃圾邮件。 他们每次使用另一个邮件服务器。 这里是从原来的电子邮件标题（我取代了我的电子邮件和主机：[email protected]，发件人的电子邮件和主机我取而代之：[email protected]，所有其他都没有改变）：

所以，当我在雷鸟的消息来源，我看到标题： From: Blah blah blah <[email protected]> 。 我如何阻止来自发件人（sender-website.com）的电子邮件？ 阻止IP是没有意义的，因为下次会有所不同。 我也设置了MailScanner，但也没有看到正确from标题。 我已经在MailScanner中列出了该域名。
所以你已经添加了[email protected] REJECT到你的sender_access文件，你有没有joinhash:/etc/postfix/sender_access到你的smtpd_recipient_restrictions =作为第一个选项？
您也可以使用smtp_nested_header_checks选项获得更多运气，因为它允许您检查标识符的任何非MIME标头。
