Any thoughts?

I don't think this is a problem as you do have to wait for the result
of the DATA command. If MAIL FROM SPF checks are triggered by the
DATA command it is no more thangerous than a SMTP connection without
PIPELINING support.

Surely the client can ignore to wait for the response of the DATA
command but that'd be RFC incompliant and the server, if configured
properly, will reject the client. This is function is implemented
in modem MTAs to prevent spammers who just go ahead with pumping their
data into the server.
