meinedomain ist die Domain der Mailadresse

So wie es aussieht kommt alles von einer einzigen IP.
Die Logs wurde alle Gesichert und der Server erstmal heruntergefahren bis das Loch gefunden worden ist.
Wie kann sowas passieren? Der Server ist seit knapp 1 Woche Online, es ist ein Frisches Squezze mit ISPCP
Installiert wurden unter anderem:

Fail2Ban
mod_evasive
SSH Key
Port geändert
Root Login nicht möglich

Wie kann ich nun das Loch am Besten finden? Was würdet Ihr emfehlen?
 
Worin siehst du konkret ein Problem?

E-Mail-Header und Envelope-Informationen kann man beliebig fälschen. Nur weil sich ein Mailclient herausnimmt, sich deinem MTA gegenüber mit dem Absender postmaster@example.com zu identifizieren, ist noch lange nichts kaputt. Willkommen im Internet.

Eventuell willst du dich auch ein wenig über die Funktionsweise von SMTP im Allgemeinen informieren.
 
Das es machbar ist ist mir klar aber es lief wohl alles über meinen Server, so sagt es auch der Traffic.

Weder noch. Ein externer Client hat eine Mail für eine Domain bei deinem MTA eingeliefert, für welche dieser sich zuständig fühlt. Nicht mehr und nicht weniger.

Du kannst den MTA beenden.

Natürlich könnte man auch einfach prüfen, ob ein Client, der als Absender eine E-Mail-Adresse mit einer deiner Domains verwendet, auch authentifiziert bzw. allgemein dazu berechtigt ist, bevor man diese annimmt. Postfix bietet dazu diverse Möglichkeiten.

Hast du da ein paar Stichpunkte wonach ich Suchen sollte?
 
In dem ganzen Logwust steht nur, dass Dein Postfix eine Mail von Paypal gegreylistet und die From/To postmaster@ angenommen hat, der Rest wurde mit unterschiedlichen Begründungen abgelehnt.

Du solltest Dir dringend einiges an Fachliteratur zulegen und den Inhalt innerhalb weniger Tage aus dem FF anwenden und wiedergeben können. Andernfalls möchte ich Dich eindringlich darum bitten, den Server solange komplett vom Netz zu nehmen, bis Du es kannst. Vielen Dank im Voraus.
 
Das ist schätzungsweise sowieso eine dynamische Internetprovider IP, die schon 24 Std später jemand anderes hatte. Ergo: Nein, das bringt nichts, wenn man nicht anfangen will, ganze Länder per Geo IP auszuschließen.
