	Nope, it works exactly as specified.
	(I have narrowed the transcripts somewhat)

	In PIPELINING the preceeding 3 lines are buffered (in stdio!)
	before they are flushed into the SMTP socket.
	The flush-point is here at sending DATA command.

	A long latency connection will thus get MAIL/RCPT+/DATA
	commands sent, and replies to them received in overlapping
	fashion.  It will start to study the incoming responses now.

> r       552 message too large

		("MAIL FROM:<..> .. SIZE=3.2 MB")
	In fact the smtp-ta should not send this message there at all,
	as it can do the comparison too from the EHLO response.
	A minor (?) omission to fix regarding SIZE processing.

> r       501 RCPT TO must be preceded by MAIL FROM command.

		("RCPT TO:<..>")
	It was sent in pipeline, and because MAIL FROM reply was
	processed delayed, so was this one.

> r       503 Need MAIL FROM command first.

		("DATA")
	Like above.

> w       RSET

	Per specification.
