imagine a mail with an empty Subject: for two recipients. The first recipient

This is what happens at SMTP level:
EHLO xx
250 blah blah
MAIL FROM:<me(_at_)example(_dot_)org>
250 OK
RCPT TO:<one(_at_)example(_dot_)com>
250 Okay
RCPT TO:<two(_at_)example(_dot_)com>
421 Retry soon retry=00:00:00
DATA
Subject:
From: me(_at_)example(_dot_)org
Message-Id: 12a
To: one(_at_)example(_dot_)com, two(_at_)example(_dot_)com
....
.
550 You forgot to fill the Subject!
How would the server know to give the two different responses to the
RCPT TO?
Or does it just always temporarily reject any messages for
'two(_at_)example(_dot_)com', just in case?
