海外ISPに苦情を申し立て(メールサーバーへの不正アクセス)

ググっても見つからなかったので自力で解決を試みました。
昨年の12月から一部のIPアドレスにおいて、メールサーバへしつこく不正ログインを試みるヤカラがいました。
その都度、ブロックしたりしていたのですが、それでもログを見るとバンバンやってきていました。
こちらで打てる手が全部なくなったので、最終手段としてfail2banで届いたメール内容から苦情申し立てのメールアドレス(abuse@xxxxx.xxxxx)に次の内容で送りました。


-----
タイトル:Warning statement
-----
内容
A petition

The next IP address intermittently makes unauthorized access to the mail server of this site from February 2018.

94.102.50.96

I am taking measures here, but I do not have a sign to stop it.
Please take measures (stop measures) immediately there.
The attached file is a mail item that detected unauthorized access that we received so far.
-----
こんな感じです。これに、fail2banで送られて来たメールアイテムを添付し、mail.logで当該IPアドレスを引っかけて貼付して送りました。


送っても暫くは不正アクセスを試みてはいたのですが、2日後くらい見るとピタッと止まりました。
やっぱりやってみるもんだなぁ。と思います。
全ての海外ISP(プロバイダー)に通じるとは思いませんが、何もやらないよりかはマシじゃないかと思います。
もう、本当にしつこくて。
毎日、数時間おきにFail2Banのメールが届くんですよ。
もしかして、Fail2Banが機能していないんじゃないか?と思って、「Postfixで相変わらずな不正アクセスを阻止」の方法もやってみたのですが効果有りませんでした。

本来ならFail2Banで効果があるはずなのですが、どう言う訳かOSバージョンアップしてからその効果が出ていないようです。
これについては、色々調査しているのですが、断定出来る箇所が見つからないのが実情ですね。
う~ん、iptablesによるIPアドレス拒否も出来ているのになぁ。
