我不确定我这里出了什么问题。它曾经在Ubuntu 18.04, 但没有在20.04看起来是这样。我已经unbound
设置了 DNS 服务器:
unbound-control status
version: 1.9.4
verbosity: 1
threads: 1
modules: 3 [ subnet validator iterator ]
uptime: 314 seconds
options: reuseport control(ssl)
unbound (pid 1074177) is running...
在/etc/resolv.conf我有:
#domain members.linode.com
#search members.linode.com
#nameserver 212.71.252.5
#nameserver 212.71.253.5
#nameserver 178.79.182.5

#nameserver 109.74.194.20
#options rotate
nameserver 127.0.0.1
options edns0
search members.linode.com
在 /etc/spamassassin/local.cf 中我有:
dns_server 127.0.0.1
我已经重启了服务器,但似乎
0.0 RCVD_IN_DNSWL_BLOCKED RBL:管理员通知:对 DNSWL 的查询已被阻止。请参阅 DNS阻止列表 了解更多信息。[209.85.218.53 已列在 list.dnswl.org 中]
我是否遗漏了什么?

正如建议的那样,这里是输出sudo ss -lntp|grep 53
:
LISTEN 0 256 127.0.0.1:53 0.0.0.0:* users:(("unbound",pid=783,fd=6))
LISTEN 0 4096 127.0.0.53%lo:53 0.0.0.0:* users:(("systemd-resolve",pid=524,fd=13))
LISTEN 0 256 127.0.0.1:8953 0.0.0.0:* users:(("unbound",pid=783,fd=7))
LISTEN 0 256 [::1]:53 [::]:* users:(("unbound",pid=783,fd=4))
答案1
编辑:如此处所述->https://www.linode.com/community/questions/21413/rcvd_in_dnswl_hi-false-positives我们知道 linode 用户遇到了这个问题。看起来您的 DNS 查询是通过 linode 的解析器转发的,但由于太多用户都通过它们转发,因此解析器被阻止了。根据 systemd-resolve --status 的输出:
DNS Servers: 176.58.107.5
212.71.253.5
151.236.220.5
我会仔细检查 unbound 是否确实在运行-> sudo ss -lntp|grep 53 仔细检查它的配置是否为递归服务器,并将 systemd-resolve 设置为查询它的上游。systemd-resolve --set-dns=SERVER 或 vim /etc/systemd/resolved.conf
