You could try disabling pipelining via pipelining_advertise_hosts.
pipelining_advertise_hosts is "expanded before use" so you could
possibly disable it conditionally for the offending user's hosts.

FWIW, I disable pipelining for an external connections here, because
it makes smtp_enforce_sync *way* more effective at blocking
spamware/malware generated messages. But mine is not a high volume
site...
