those entries come from courierlocal, which delivers the message. 'real' bounces are all handled by courieresmtpd itself. Guess some utility (maildrop or dotfile) returns a non-zero exitcode.

thats your server busy sending back bounces to the (possibly forged) senders Mega@777.net.cn and just@xmailsex.com.

The latter deferred messages actually have a reason why they were deferred, but the former do not.

They have nothing in common, you need to investigate further.

The incoming spam should be rejected via esmtpaccess, dnsbl, bofh or courierfilter, dont bounce once received and accepted and it will be much easier to spot the 'real' problems in the logs ;)
