Ich habe ein Anti-Spam-System basierend auf „Postfix“. Wenn jemand eine E-Mail sendet und von einer Blacklist blockiert wird, erhält er eine Rückmeldung.
Beispiel unten:
This is the mail system at host mail.xxx.com.
I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.
For further assistance, please send mail to postmaster.
If you do so, please include this problem report. You can
delete your own text from the attached returned message.

by Block Address check from xx.xx.xx.xx (in reply to RCPT TO command)
Wo kann ich 535-Fehlerbenachrichtigungen deaktivieren?
