IMHO there is some bogus advice there. If Postfix's
"reject_unauth_pipelining" is not working aright
then you can't trust it to work right, barring some
CHUNKING-specific bug that bites on BDAT and does
not bite on DATA.

Also, a client not waiting for a server response to
a BDAT LAST is broken, because it cannot be sure that
a) all the data got to the server b) the server does
not do data scanning (e.g. antivirus) and rejects.
So it's far from useless, despite what that page says.
