Unfortunately, Postfix cannott predict the future (if it could,
then I would be doing something else).
Before the entire message is received, Postfix uses the SIZE
information sent by the remote SMTP client. Postfix knows the true
message size only after the remote SMTP client sends "end-of-data".
This SMTP protocol stage does not have per-recipient replies, so a
REJECT reply would block the message for all recipients.
