Ja, wollte nur mich ganz Klar an die Richtlinien für das posting in die maillist halten.
Ich paste mal das selbe log nicht so sehr modifiziert.

Zwei Relaydomains: relaydomain1.com un relaydomain2.com

Nein, nur relay_recipients. Kein Amavis, kein spamassasin, nur Postfix. Ist nur ein incomming mail-relayer für 2 domains.

Ja, ich habe darüber gelesen und würde gerne nicht einsetzen, bin mit der default "Antwort" zufrieden wenn es defaultmäßig gehandelt würde, also die Email "defern", aber nicht zustellen.
Mir geht es mehr ums verstehen und andere Sendungen vorzubeugen, warum in der gleichen Connection 4-5 mal richtig gehandelt wird, aber einmal zugestellt wird. Aus den logs geht hervor das das andere System nach den 1en versuch, plötzlich eine Email ohne FROM sendet und das Postfix diese zustell ohne weitere Überprüfungen zu machen (reject_unknown_sender_domain status=0, zum Beispiel).
Ich habe dieses Problem mit nur 2 Sendern, das andere sendet mit root at linux2.host, was da geschieht ist noch schlimmer, da rejected Postfix mit ein 550 code, ist zudem noch in der sender_access list, wird aber trotzdem zugestellt:

Wir haben täglich etwa 100.000 Zustellungen zu relaydomain1.com, davon werden etwa 2000 Emails relayt, der rest wird rejected hauptsächlich, außer diese zwei Sender.

Die docu habe ich mir zigmal von oben bis unten durchgelesen und in andere Systeme probiert bevor ich gepostet habe, nur das oben geschilderte Problem kann ich nicht im test-server wieder reproduzieren da es sehr selten vorkommt, 2 mal am tag von 2 verschiedene Sendern unter etwa 10.000 Sendern. Abgesehen davon, wie du oben am log und an der sender_access list sehen kannst, die zweite mail darf unter keinem Umstand zugestellt werden, tuts aber.

Die sache ist die, ich muß unbedingt in jeden restriction-stage in der lage sein ein Sender zu erlauben zu senden ohne dabei das mailsystem zu weit zu öffnen, komm aber mit unseren ersten postfix-server und den restriction-stages nicht ganz klar.

Ok, werde ich versuchen!
