最近、postfix を使用してメールサーバーを立ち上げました。DKIM や rDNS などの多くの構成と設定を行った後、残念ながら、Gmail への送信メール メッセージはまだ受信トレイからブロックされています。(スパムを取得)
自信をつけるために次に何をすればいいのか、今はまったくわかりません。
これは、Gmail が私のメール サーバーから受信した最新の「元のメッセージ」です。

==========================================================
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.
