I don't understand why this should be impossible.
If the dialogue would walk like this:
C: MAIL FROM: <bigbinary@???> SIZE=10000000
S: 250 Ok
C: RCPT TO: <frank@???>
S: 250 Ok
C: RCPT TO: <dan@???>
S: 550 This recipient does not want mails crossing 2 MB in size
C: DATA
...
.
The sender would be notified which recipients did not want to
receive the big mail. If all recipients would reject the message,
the message would not be actually transmitted.
