我有一个VPS，我们托管了多个域。我们的电子邮件面临问题，因为来自我们少数域名的电子邮件总是在gmail的垃圾邮箱中提供。我们为所有域添加了DKIM和SPF。在我未能解决问题之后，我也试图联系我的托管服务提供商（Host IT Smart）。他们也无法找到任何解决方案。你能建议我解决这个问题吗？以下是verifier.port25.com的回复
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-feedback@port25.com>.
Thank you for using the verifier,

NOTE: DKIM checking has been performed based on the latest DKIM specs

older versions. If you are using Port25's PowerMTA, you need to use
version 3.2r11 or later to get a compatible version of DKIM.

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.

gmail有自己的垃圾邮件检测系统，您的DNS /邮件服务器配置看起来很好而且稳固。从那些事实我会假设 - 要么发送（作为消息主题/正文）某些被gmail视为垃圾邮件的内容 - 或者您的域名/ IP地址与gmail有关的错误历史记录（假设您在配置服务器的过程中尝试过早地发送一些未正确配置邮件域的测试电子邮件）。 Gmail记录了这些不良尝试，并且由于过去的历史记录将其视为垃圾邮件。
我建议将几封电子邮件发送到您自己的Gmail帐户，并从那里的垃圾邮件文件夹中删除这些电子邮件（不是垃圾邮件），这可能会告诉Gmail垃圾邮件检测引擎停止将您域中的电子邮件视为垃圾邮件。

Gmail现在有一个postmaster工具，您可以检查您的域/ IP信誉历史记录，垃圾邮件率以及＆＃34;身份验证＆＃34;您可以检查DKIM / SPF / DMARC正常工作的区域。
我建议使用CNAME记录进行身份验证，如果您在SPF查询此条目返回时也使用默认的TXT记录。
