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
