Here's why I say that: because of a race condition documented in RFC 
1047, SMTP servers should try to minimize delay between the receipt of 
CRLF.CRLF to end the message and the sending of a reply.

The current draft model deals with this by immediately returning a 353
response code (or any other valid response, such as 250/550) after the
end-of-data sequence.

Any additional delays that would be incurred from per-user inspection of
the content would come after that immediate response.
