これは パターンとして 一度 訪れた後 メールを 送信するように と 依頼 （そのような やさしい態度では無いが）しているようです まず 最 初の 訪問パターンは
Jun 9 18:31:03 k599V28b004525: [222.122.60.184] did not issue
MAIL/EXPN/VRFY/ETRN during connection to MTA
つまり did not issue ... during connection to MTA という形で もって 接続 してきます この時には これだけで 終わるのですが その後で メールの 送信（転送）依頼が来ます 必ずしも 常に 対応する理由では 有りませんが 概ね その様な 動きを しています ちなみに ”DShield.org Distributed Intrusion Detection System”で 調べると この時点では 札付の ものの 様です

上記で調べる事が可能です いやー チャング厶 の 世界ですな 悪い奴も 一 杯 いるようです
IP Address: 222.122.60.184 HostName: 222.122.60.184 DShield Profile: Country: KR
ここの いやらしい所は 中継してもらうサーバー この例 では” nyanco.catland.king”というが あたかも 差出人の サーバーからに なっていると 言う事です。つまり
受信者アドレス receiveduser@gmail.com 接続元サーバ 名前は有りません IP Adr [222.122.60.184] 送信元アドレス senduser@nyanco.catland.king
わかり難い 図示をしてみると
senduser@nyanco.catland.king
| この部分は きっと 偽りであろう
V nyanco.catland.kingから依頼した覚えは無い
[222.122.60.184] KR より 依頼が くる

nyanco.catland.king IP Adr [123.456.78.91]

V 受け取りは
receiveduser@gmail.com
親切に 手紙を 代筆して 差し上げましょう と云うことのようです でも そ んな 親切は してもらわない方が 良いと 考えます。ちなみに 差出人と 受け取り人 は
差出人 testusrrr@nyanco.catland.king testuser5@nyanco.catland.king | V 受取人 msgtrap2@gmail.com robertab541@gmail.com 差出人 angsty5x@nyanco.catland.king atmpXXlt@nyanco.catland.king | V 受取人 charliem634@gmail.com satchel234@gmail.com rexm5hjz@gmail.com
何で そんなに 親切なんだろう ちなみに わたしんちnyanco.catland.kingには ユーザー ”testusrrr”” testuser5”、”angsty5x”、”atmpXXlt”という方は 存在しないし また ” gmail.com”の 中に ”msgtrap2”、”robertab541”、”charliem634”、” satchel234”、”rexm5hjz”というユーザーが いるのか どうかは感知しません 。すくなくとも わたしんちは 関係ないことである。
ウーーーン 色々な足跡が有りますネ とにかく お断りはしているようですが
にゃんたろう 拝！
