I read the postfix backscatter readme today.
Up until now it seemed like a good idea to always bounce
undeliverable email, so people can realize their typos.
But this seems to be a spammer technique to deliver
via forged from addresses.
I'll have to convince people setting
unknown_local_recipient_reject_code = 550
in postfix is a good idea.
How many of you use this (or similar) in your MX server?
