Q&A
メールが送信できなかった時のmaillogを質問に追加してください
CentOS7.5
Postfix2.10.1-6.el7.x86_64
dovecot2.2.10-8.el7.x86_64
自宅サーバを構築しており、メールサーバを立てているのですが、受信はうまく行き問題ないのですが、送信が、メールクライアントでは送られているのですが、宛先に送られていない状況です。
https://centossrv.com/postfix.shtml
このサイトを見て構築しました。今後、暗号化までやりたいと思っているのですが、その前の平文での送信ができず困っています。
自宅サーバならop25bの可能性が高いですね。
認証エラーを起こしてますね。パスワードなどを確認してください。また個人が特定できる情報はマスクした方がいいです。不正アクセスされますよ。
ユーザ名もパスワードも正しいものがセットされています

今まで、動いていたのが、急に送信できなくなったのでしょうか？
それとも サーバーを再構築して送信できなくなったのでしょうか？
自宅サーバーということなので、お使いのプロバイダによる Outbound Port 25 Blocking(OP25B) の可能性が高そうです。
お使いのプロバイダ名と現在の Postfix の設定(smtp_xxxx まわり)を公開することは可能でしょうか？ (IPアドレス、ユーザー名やパスワード等は、適当に置き換えてしてください。)
参考情報
参考にされた メールサーバー構築(Postfix+Dovecot) にも 真ん中ぐらいに 「OP25B対策」の項目があり、リンク先の OP25B(Outbound Port 25 Blocking)対策 に設定が書かれていますので、一度確認して見てください。
なお、OP25B(Outbound Port 25 Blocking)対策 では、Gmail のサーバーを使って中継していますが、可能であれば、お使いのプロバイダの SMTP サーバを経由する方が良いと思います。
(2018-09-06 23:40追記)
メールログで、
- SASL authentication failed; cannot authenticate to server
- no mechanism available
のエラーが出ていますが、 libsasl2 は、インストールされていますか？
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
/etc/postfix/sasl_passwd を書き換えた後 postmap は、実行されていますか？
smtp_use_tls = yes
になっていますが、プロバイダの設定マニュアル SMTP-AUTH設定方法(Windows) では、暗号化をチェックしていないようです。
暗号化を NO にするとどうなるでしょうか？
(追記 2018.09.07 23:30)
思いつく点は、書いたと思うので、リレー先ホストとの通信内容をログに記録して、追いかけないとダメかな...
main.cf に
debug_peer_list = msa3.across.or.jp
を追加して、 postfix reload で再起動してください。
メールを送信すると msa3.across.or.jp との通信内容がログに記載されるようになるので、ユーザー名やパスワード等の重要部分を置き換えて、質問に追記してもらえないでしょうか。

確かにこれは調べていて、気になっていたところなんですが、yumではパッケージがインストールされていると出るの出るのですが、grepでは出てきませんでした。rpmで入れて見ましたが、エラーメッセージは変わりません。
/etc/postfix/sasl_passwd を書き換えた後 postmap は、実行されていますか？
しています。
smtp_use_tls = yes
になっていますが、プロバイダの設定マニュアル SMTP-AUTH設定方法(Windows) では、暗号化をチェックしていないようです。
暗号化を NO にするとどうなるでしょうか？
エラーメッセージは変わりません。
sasl_passwd の中身は、`リレー先ホスト名 ユーザ名:パスワード` のように relay 先ホスト名は、間違っていないですよね？
もしかすると `[msa3.across.or.jp]:587 ユーザ名:パスワード` のように relayhost と同じ文字列にしないとダメなのかなぁ... ( うちの環境では、 relayhost は [hostname]:587 ですが、 sasl_passwd は、`hostname user:pass ` で動いているので問題ないと思っているのですが... )
relayhostと同じ文字列にしてあります。
追記いただいた、logはmaillogに書き込まれますか？
はい。maillog に記録されます。
通常のログの間にサーバーとのやりとりが記録されます。
１回の通信で60行ぐらい記録されるので、確認が終わったら追記した内容を削除してください。

「no mechanism available」とのこと、cyrus-sasl-plain がインストールされていないからだと思います。
yum install cyrus-sasl-plain
###(2018/09/09 15:40) 追記
CHERRY さんの回答のデバッグログから:
Sep 9 09:02:21 suzunet postfix/smtp[10369]: name_mask: noplaintext Sep 9 09:02:21 suzunet postfix/smtp[10369]: name_mask: noanonymous
smtp_sasl_security_options のデフォルトが noplaintext, noanonymous で、認証方式 PLAIN, LOGIN は両方とも noplaintext 制限に引っかかります。
smtp_sasl_tls_security_options = noanonymous が効いていなかったのでしょうか？
もう一度、以下の設定を確認ください。
smtp_sasl_security_options = noanonymous smtp_sasl_tls_security_options = noanonymous

パッケージ cyrus-sasl-plain-2.1.26-23.el7.x86_64 はインストール済みか最新バージョンです
何もしません
以上のようにインストールされています。
すみません。当てが外れました。
メールログを見返すと、"postfix/smtp" ではなく "postfix/error" となっているので、ここに何か原因があるのではと思います。
