后缀reject_rbl_client黑名单无效

Question

我有一个使用后缀的邮件服务器(iRedMail)。我收到了很多垃圾邮件，所以我修改了/etc/后缀/main.cf文件，并将smtpd_recipient_restrictions设置为：

smtpd_recipient_restrictions =
        reject_rbl_client zen.spamhaus.org,
        reject_rbl_client bl.spamcop.net,
        reject_rbl_client cbl.abuseat.org,
        reject_rbl_client b.barracudacentral.org,
        reject_invalid_hostname,
        reject_unknown_sender_domain,
        reject_unknown_recipient_domain,
        check_policy_service inet:127.0.0.1:7777,
        check_policy_service inet:127.0.0.1:10031,
        reject_non_fqdn_sender,
        reject_non_fqdn_hostname,
        reject_non_fqdn_recipient,
        reject_unlisted_recipient,
        permit_mynetworks,
        permit_sasl_authenticated,
        reject_unauth_destination,
        permit

然而，垃圾邮件仍然来自这些黑名单上的IP。

如果我查看我的/var/log/mail.log文件，就会看到消息通过。下面是一个例子：

Jan 11 01:09:19 mailhost postfix/smtpd[935]: DA5736B578: client=localhost[127.0.0.1]

当我在MXToolBox上查找89.185.243.3时，它被列在Spamhaus上。

配置不正确吗？我注意到，很明显，这些物品的顺序不同。

谢谢!

您的配置不是最优的，最好在客户端限制中使用RBL。这是我的建议，虽然有些是限制性的，我不知道你完整的后缀设置。这是一个示例，有关params…的更多信息，请参见后缀手册和建议。

smtpd_helo_restrictions =
    permit_mynetworks,
    permit_sasl_authenticated,
    reject_unauth_pipelining,
    reject_non_fqdn_hostname

smtpd_client_restrictions =
    permit_mynetworks,
    permit_sasl_authenticated,
    reject_unauth_destination,
    reject_rbl_client zen.spamhaus.org,
    reject_rbl_client bl.spamcop.net,
    reject_rbl_client cbl.abuseat.org,
    reject_rbl_client b.barracudacentral.org

smtpd_sender_restrictions =
    reject_non_fqdn_sender,
    reject_unknown_sender_domain,
    permit_mynetworks,
    permit_sasl_authenticated,
    reject_authenticated_sender_login_mismatch,
    reject_sender_login_mismatch

smtpd_recipient_restrictions =
    reject_unknown_recipient_domain,
