Ralf, your inattention to detail disappoints me. :-(
The correct reply to "DATA" is "354" not "250". Something is awfully
out of sync if Gmail is returning "250" in response to "DATA".
That's presumably a response for one of the recipients, so Gmail
sent one more response than Postfix expects, or Gmail received
one more command than Postfix expected to send.
