When a server identifies itself as supporting the DATAFIRST extension,

So you'll have to accept the data even though there may be no valid
recipient?
I'd think an extension where the responses to RCPT was delayed until
after DATA would be much more useful! That way you could reject DATA if
there has been no valid recipients, while keeping the ability to do
per-recipient content scanning.
