I use Zimbra to run our personal servers. Not for a client or business. I need to turn off NDR as I have problems with what I think is Backscatter/NDR spam. Essentially, someone has used my personal email address as the from on spams. My server is not open relay, it is just for some reason they used my email address. So I am receiving literally thousands of NDR messages.
I have tried using the backscatter how to for postfix and changing bounce emails to discard in the postfix master.cf to no avail. Any other thoughts?
I just want NDR turned off to completely alleviate this problem.
