我在尝试让我的公司电子邮件从 Port25s 身份验证验证服务返回更好的分数时遇到了一些麻烦。我对大多数结果的评分都是中立的。我已将报告附在下面。
我遇到过反向 DNS，有人告诉我这对于证明我的邮件服务器的可信度至关重要？对我的 IP 地址进行反向 DNS 检查后，结果为
ip-97-74-4-207.ip.secureserver.net
这是正确的吗？还是我应该联系我的托管服务提供商？
我认识到这个问题的模糊性并且深感抱歉，我缺乏这方面的知识，如果有人能给我指明正确的方向，我将不胜感激。

Subject: Authentication Report
This message is an automatic response from Port25's authentication verifier service at
verifier.port25.com. The service allows email senders to perform a simple check of various sender
authentication mechanisms. It is provided free of charge, in the hope that it is useful to the email
community. While it is not officially supported, we welcome any feedback you may have at <verifier-
[email protected]>.
Thank you for using the verifier,

==========================================================
Explanation of the possible results (from RFC 5451)
==========================================================
SPF and Sender-ID Results
=========================
"none"
No policy records were published at the sender's DNS domain.
"neutral"
The sender's ADMD has asserted that it cannot or does not
want to assert whether or not the sending IP address is authorized
to send mail using the sender's DNS domain.
"pass"
The client is authorized by the sender's ADMD to inject or
relay mail on behalf of the sender's DNS domain.
"policy"
The client is authorized to inject or relay mail on behalf
of the sender's DNS domain according to the authentication
method's algorithm, but local policy dictates that the result is
unacceptable.
"fail"
This client is explicitly not authorized to inject or
relay mail using the sender's DNS domain.
"softfail"
The sender's ADMD believes the client was not authorized
to inject or relay mail using the sender's DNS domain, but is
unwilling to make a strong assertion to that effect.
"temperror"
The message could not be verified due to some error that
is likely transient in nature, such as a temporary inability to
retrieve a policy record from DNS. A later attempt may produce a
final result.
"permerror"
The message could not be verified due to some error that
is unrecoverable, such as a required header field being absent or
a syntax error in a retrieved DNS TXT record. A later attempt is
unlikely to produce a final result.
DKIM and DomainKeys Results
===========================
"none"
The message was not signed.
"pass"
The message was signed, the signature or signatures were
acceptable to the verifier, and the signature(s) passed
verification tests.
"fail"
The message was signed and the signature or signatures were
acceptable to the verifier, but they failed the verification
test(s).
"policy"
The message was signed but the signature or signatures were
not acceptable to the verifier.
"neutral"
The message was signed but the signature or signatures
contained syntax errors or were not otherwise able to be
processed. This result SHOULD also be used for other
failures not covered elsewhere in this list.
"temperror"
The message could not be verified due to some error that
is likely transient in nature, such as a temporary inability
to retrieve a public key. A later attempt may produce a
final result.
"permerror"
The message could not be verified due to some error that
is unrecoverable, such as a required header field being
absent. A later attempt is unlikely to produce a final result.

好吧，你至少应该设置 DKIM 基础设施。如果你知道自己在做什么，这并不难。我建议你从这里开始：http://www.gettingemaildelivered.com/dkim-explained-how-to-set-up-and-use-domainkeys-identified-mail-effectively
然后我将修改 SPF 记录，将“~all”更改为“-all”。您必须确保来自您域的所有邮件都由指定 IP 的服务器发送。
这样，你应该能在两次考试中取得好成绩，从而提高你的声誉。
