以下元素

# postconf myhostname

# postconf mydomain
mydomain = example.com
# postqueue -p

87C5DDD44B*     418 Mon Jan  6 13:02:36  root@ubuntu-4gb-nbg1-1
                                         [email protected]

导致收件人邮件服务器超时：

connect to in-smtp.example.org[192.0.2.1]:25: Connection timed out

邮件发件人标识from=<root@ubuntu-4gb-nbg1-1>为mail.log。

hostname.example.com和拥有其example.com适当的 DNSA记录和TXT SPF允许的记录ip4:198.51.100.1。

服务提供商（在本例中为 Hetzner）具有针对设置为 的主 IPv4 地址的反向 DNS 条目example.com。

我以为是邮件发件人字符串被 MX 服务器拒绝了。但是当我这样做时， 日志中出现了正确的发件人。mail -s 'subject' "From: [email protected]" [email protected]

那么配置可能缺少什么呢？

上下文：
• 由第三方处理的电子邮件服务
• VPS 具有 Postfix 作为仅发送邮件服务器。

DNS 有两个 TXT 记录，名称为@
v=spf1 include:spf.someengine.com ?all
v=spf1 mx ip4:111.222.333.444 ~all

这种配置会给邮件服务器带来问题吗？最好将它们统一到一个条目中，例如
v=spf1 include:spf.someengine.com mx ip4:111.222.333.444 ~all ？

其中的文件/etc/nginx/sites-enabled包含以下内容

server {

  server_name production.domain.club cspiero.domain.club;
  root /home/deploy/domain/current/public;
[...]
   ssl_certificate /etc/letsencrypt/live/cspiero.domain.club/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/cspiero.domain.club/privkey.pem; # managed by Certbot
[...]
server {
    if ($host = production.domain.club) {
        return 301 https://$host$request_uri;
    }
  listen 80;
  listen [::]:80;
}
server {
    if ($host = cspiero.domain.club) {
        return 301 https://$host$request_uri;
    }
  listen 80;
  listen [::]:80;
}

当nginx -t通过时，服务器的实际行为是第三级域名production按预期呈现，而cspiero不是被路由到同一位置，而是由默认配置处理（浏览器也会收到http响应，从而忽略证书） ）

server {
       root /home/deploy/default;
        index index.html;
        server_name _;
        location / {
        try_files $uri $uri/ =404;
        }
}

为什么会发生这种情况？希望维持所有其他钓鱼探险请求的默认配置（渲染非常轻且平淡的东西）。那么在这种背景下应该做什么呢？

以下错误阻碍了opendkim的重启

× opendkim.service - OpenDKIM Milter
     Loaded: loaded (/lib/systemd/system/opendkim.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Sat 2023-04-22 08:00:27 UTC; 2s ago
[...]    Process: 2295 ExecStart=/usr/sbin/opendkim (code=exited, status=78)
opendkim.service: Control process exited, code=exited, status=78/CONFIG

尝试查阅（未加密的，可能未更新的）文档，没有发现任何关于status=78.
但显然 milter 配置在某种程度上是不正确的。 /etc/postfix/main.cf 定义：

# Milter configuration
milter_default_action = accept
milter_protocol = 6
smtpd_milters = local:opendkim/opendkim.sock
non_smtpd_milters = $smtpd_milters

而/etc/opendkim.conf有

Syslog                  yes
SyslogSuccess           yes
LogWhy                  yes

PidFile                 /var/run/opendkim/opendkim.pid
# UserID                  opendkim:opendkim

我注意到以下几点：
• 最初引用的 opendkim 配置ExternalIgnoreList refile:/etc/opendkim/TrustedHosts而现有文件是/etc/opendkim/trusted.hosts. 这对整个块重复。整个块被修改为小写的点分隔文件名，然后服务重新启动。

但是，电子邮件在发送时会被 postfix 记录为： warning: connect to Milter service local:opendkim/opendkim.sock: No such file or directory

cd /var/spool/postfix/opendkim
-bash: cd: /var/spool/postfix/opendkim: No such file or directory

我也看不到 pid 文件/var/run/opendkim/

smtpd_milters = local:opendkim/opendkim.sockpostfix配置和 opendkim定义之间可能存在一些错误Socket。需要改变什么？

更新
warning: connect to Milter service local:opendkim/opendkim.sock: Permission denied仍在邮件日志中，因此该配置元素是错误的。

将设置更改postfix/main.cf为

smtpd_milters = local:/var/spool/postfix/opendkim/opendkim.sock

结果： warning: connect to Milter service local:/var/spool/postfix/opendkim/opendkim.sock: No such file or directory。的存在/var/spool/postfix/opendkim/opendkim.sock得到验证。

下面的块

    location ~ /(wp-content|solr|jsonws|mifs|wp-includes|login.asp)/ {
        return 404;
    }

处理en/blog/wp-includes/wlwmanifest.xml不当。目的是处理任何包含 stringwp-includes等的请求。

我希望 nginx 返回 404 错误，而访问是访问应用程序服务器。

语法错误在哪里？

对反向 DNS 适用于什么以及在何处设置感到困惑......虽然有关于如何做到这一点的答案，但我仍然无法确定需要完成什么以及为什么。

域在 Registrar A 处注册，其中包含 DNS 表。注册商 A 还通过其拥有的域提供邮件服务。两个 VPS 提供不同的 3 级域服务。

DNS 表中的 spf 记录指向 MX 服务的邮件服务器的域，而 MX 记录指向

mail.registeredDomain.com

v=spf1 a mx ptr include:mailServer.net ~all

MX 工具箱状态Reverse DNS does not match SMTP Banner

是基于服务 (mx) 还是域的反向 DNS 查找？我可以看到与 MX 记录不匹配，但邮件提供商已按照说明设置 PTR 记录。

SPF PTR记录应该如何设置？为什么？
