Okay I am now down to maybe 5 emails per 24 hours that are backscatter
bounces from existing mail names.
Can anyone see anything wrong here please? From reading I need to use
header and body checks? ( How do I block backscatter mail to real
recipient addresses?
<http://www.postfix.org/BACKSCATTER_README.html#real> ), but am unsure
what to use in the code.
You are the source of backscatter, not the victim. The
BACKSCATTER_README won't help you.
Postfix isn't the problem; the problem appears to be some spam
filter in your email delivery path that is bouncing unwanted
mail. Don't do that.
I can't help you any further. Good luck.
