Undelivered Mail Returned to Sender Problem - 40k emails bekommen (und es geht weiter)

    Hallo,


    seit ca 1 std bekomm ich hunderte Undelivered Mail Returned to Sender Emails in mein postfach, jetzt sind es inzwischen 40.000 Stück.
    Ich glaube nicht das meine E-Mail gehackt ist, ich denke jemand spoofed meine email als absender und ich bekomm all den scheiß der nicht delivered werden kann.
    Ich glauben wegen dieser High Load ist spamassassin auch down und filtert nichts mehr.


    Was kann ich tun damit das ganze aufhört ?


    Bitte um schnelle tipps.


    Gruß,
    salexes


    Edit: Jetzt sind es 41k

    Steht was im Log? Irgendein phpScript das aufgerufen wird?

    nano /var/log/mail.log


    Kannst ja auch erstmal den postfix stoppen. Dann wird nichts mehr verschickt, wenn es von dir kommt.
