With SMTP this is architecturally not possible for multi-recipient
mail. A single message may require multiple downstream deliveries
and some may succeed while others tempfail or hardfail. With alias
expansion this can even happen for what is initially a single-recipient
message.
This also seems like a rather bad idea. Instead, use the DSN NOTIFY
ESMTP extension, which is the right wait to be notified of delivery
completion and status.
