It answers your question. Even in 2.7 there is no buffering with milters.
Only pre-queue proxy filters are buffered. Milter behaviour is unchanged
from 2.6.

environment. If you are interested, please drop me a note.

No, my question was about how things behave in general, not specific to
2.7. That answer came from Sahil. All Wieste said is that "Milter
applications see the SMTP commands as they happen". I specifically said,
in fact, in my email, that I was pretty sure 2.7 did not address the
concern about rejected email. So many thanks to Sahil who took the time to
read my question in full.
