送信ドメイン認証導入総括

今回新サーバに導入の覚書です。

上記手順でインストールは問題なく動作確認もsa-test@sendmail.netへの送信テストの結果は以下

———————————————————————————————————–

sendmail.net Sender Authentication Auto-Responder $Revision: 1.19 $

This
service runs at <sa-test@sendmail.net> and allows
remote users
to perform a simple, automated test to see if different
Sender
Authentication schemes are working.  Mail sent to this service
is
checked by our Sender Authentication filters for any valid
credentials or
signatures.  A script receives the message, checks
for a special header with
the results of the tests, and composes
this response message based on what it
finds.  This response is also
signed with DomainKeys Identified Mail
(DKIM).

Please note that the DKIM filter signing this reply message
conforms
to the latest IETF standard version, and thus may not be successfully
verified by older implementations.  If you are using dkim-filter
from
Sendmail, Inc., upgrade to OpenDKIM to be compatible with the
most
recent version of DKIM.

Note that DomainKeys has been removed in
favor of DKIM.  Sites still
using DomainKeys should upgrade to DKIM
ASAP.

We hope this service has been helpful to you.

と問題なくyahoo.co.jp宛のメールも迷惑メールには振り分けられるもののDKIM及びDomainKey認証の結果は

以下のように問題ありませんでした。

次に前回問題なかったgmail宛にテストメールを送信しヘッダー情報を確認しました。

すると前回旧サーバでDKIM署名のテストをしたときの結果と異なりました。

前回のAuthentication-Results結果
Authentication-Results: mx.google.com; spf=pass (google.com: domain of yoshio@hstech.net designates 219.105.37.35 as permitted sender) smtp.mail=yoshio@hstech.net

今回のAuthentication-Results結果

Authentication-Results: mx.google.com; spf=pass (google.com: domain of yoshio@hstech.jp designates 219.105.37.34 as permitted sender) smtp.mail=yoshio@hstech.jp;
dkim=neutral (no key) header.i=@ と叱られた

ぬ!no keyってなんじゃい!とここからgoogle先生に教えを請いました。以下次回
