postfix ipv6: mynetoworks
there's a problem with mynetworks default value, sometimes it is
something like "0.0.0.0/1 18.104.22.168/1 ....". That means open relay.
Sometimes it is something different, but it is a semi-open relay anyway
Solutions may be defining mynetworks value by hand or use
mynetworks_style, if possible.
Check your mynetworks value, please.
