OpenDKIM给出没有找到密钥的错误

Question

因此，我已经用后缀安装了OpenDKIM，我仍然可以发送电子邮件，但当我发送邮件时：opendkim-testkey -d example.com -s mail -vvv

我回来了：

opendkim-testkey: using default configfile /etc/opendkim.conf opendkim-testkey: checking key 'mail._domainkey.example.com' opendkim-testkey: No key

如果我使用check@uverfier.port25.com，上面写着

DKIM check: permerror和result: permerror (no usable key records)

但在电子邮件中，我可以看到我的公钥在电子邮件头与s=mail和d=mydomain.com等.

/etc/opendkim/被设置为opendkim:opendkim用于用户和组。

我的opendkim.conf：

# installation. For more advanced options, see opendkim.conf(5) and/or

在这方面的任何帮助都是非常感谢的。

现在就解决了。

当我把公钥放在我的DNS记录中的主部分时，我应该把它放在子域部分，并将mail._domainkey.example.com作为名称/子域。
