修复后禁用自己发送电子邮件

Question

我有个小问题。有个垃圾邮件发送者从我的地址给我发邮件。

以下是邮件标题：

邮件服务器在后缀，垃圾邮件服务器上运行。在spamassasin中，所有来自拉脱维亚adreeses的消息都是白色的。

spamassasin spam.whitelist.rules

From:           *@*.lv          yes

main.cf

smtpd_recipient_restrictions = hash:/etc/postfix/access,
        permit_sasl_authenticated,
        permit_tls_clientcerts,
        permit_mynetworks,
        check_policy_service inet:127.0.0.1:60000
        reject_invalid_hostname,
        reject_non_fqdn_sender,
        reject_unknown_sender_domain,
        reject_non_fqdn_recipient,
        reject_unknown_recipient_domain,
        reject_unauth_destination,
        permit

问题是:如果From与发送方相同，如果发件人没有身份验证，我可以在smtp级别丢弃邮件吗？

在邮件标题处，发件人是：

收到: 59.93.217.133 (未知59.93.217.133)

所以它没有经过认证。我是对的？

Answer 1

配置SPF并在后缀中使用一些spf检查框架(tumgreyspf，后缀策略-spf-perl，.)。
