Yes ..... it's already there in policyd.conf

# whitelist null sender: default: off

# null senders are normally used for bounce messages. many

# 1=on 0=off
WHITELISTNULL=0
Enabling the option will completly whitelist null sender. Tough,
it's completly unrecommended, as SEVERAL spam senders use the null
sender as the address on their messages.
I dont know (and you'll will not tell us, for sure) your spamtraps.
Almost all of my spamtraps are addresses that not even a dictionary
attack would generate. They are not words in my language (Brazilian
Portuguese) and not even in other languages I know. That way, i suppose
my spamtrap addresses will never be used in a From forged spam.
