Interesting. Do you really see that happening much? ISTM that:
1. The majority of spam & malware these days is offered directly by
spamware/malware, and as such rejection does not led to DSNs to
anybody.
2. Very little spam/malware these days is offered with the local
domain spoofed in the sender address. We get virtually none at all
here, though it's a low volume site.
3. If postmaster is a read-only address, DSNs to postmaster can be
rejected.
