I would like to block the .co.jp so it doesn't pile up in postqueue.
This seems like your email address has been used as sender_address with
some spam rejected by yahoo.co.jp (just a guess). Anyways your
MAILER_DAEMON tries to send bounces to yahoo.co.jp. You'd have to check
what's inside those bounced messages to find out what's the real
problem, I mean why your mailserver is generating those bounces.
You could reject those messages by rejecting recipients from
yahoo.co.jp. but this is not recommended.
No, his postfix is generating these bounces. His postfix
accepted mail addressed from *[email protected], wasn't able to
deliver it, and it attempting to return to sender.
Very likely these non-delivery reports are because his system
is accepting mail to non-existent recipients. He is
generating backscatter, not a victim of it.
Maybe OP has a wildcard entry in his virtual_alias_maps.
