从标题来看，bind9 不会为一个域提供 txt 记录，而为其他域提供该记录。区域几乎相等。
系统 Ubuntu 14.04 Bind9 来自发行版（也从源代码尝试了 9.10）
我有两个域名：www.filippo.fake 和 www.mimmo.fake
Filippo 的区域和 Mimmo 的区域基本相等：

但是，从 ns-1、ns-2 和世界其他地方运行“host -t txt domain localhost”会得到以下结果
显然，世界其他地方没有以“localhost”结尾的：
root@ns-1:/var/log/named# host -t txt filippo.fake localhost
Using domain server:
Name: localhost
Address: ::1#53
Aliases:
filippo.fake descriptive text "v=spf1 +a +mx +ip4:1.2.3.4 ?all"
root@ns-1:/var/log/named# host -t txt mimmo.fake localhost
Using domain server:
Name: localhost
Address: ::1#53
Aliases:
mimmo.fake has no TXT record
还有更多像 filippo.fake 这样的域名正常工作。有或没有 dkim 记录都无所谓。我已经尝试更改绑定版本，使用 ispconfig 删除并重新创建区域，手动创建 pri.mimmo.fake 区域文件。它没有改变任何东西。
日志。
直到我更改绑定版本，我才在域不起作用的日志中收到此信息：
04-Oct-2016 14:52:01.746 zone mimmo.faje/IN: 'mimmo.fake' found SPF/TXT record but no SPF/SPF record found, add matching type SPF record
但请考虑从来源安装 bind 9.10 后，警告不再显示在日志中，而 txt 的问题仍然存在。如果我创建 spf 记录，它不会改变任何东西。
每次服务重新启动时，日志中都不会显示与错误或警告相关的特定消息。无论如何，由于绑定日志记录的复杂性，我将向您展示用于记录的规则，也许我没有查看我应该查看的内容？
