Currently pigeonhole supports reject which would generate a NDR for each message. (If I understand the current documentation)

Using Dovecot LMTP it would be more optimal to kick a 5xx back to the primary MTA to reject the delivery rather than generating more back scatter NDRs

and what would that change? nothing if you think about how mail works!

• the MTA receives the message
• the MTA confirms with 2xx status code
• later the delivery server rejects
• the MTA *must* create a bounce

just don't reject mails after you confirmed you have received them in the SMTP session and if you don't want a mail after that DISCARD it by consider legal implications - there is nothing between
