according to the standard it must be a 220 reply that the server sends right
after the connection was established. so i guess you're using a very crappy
smtp server ... or you could check with the mail-admin.

of course the local smtp server knows its users (or how would you explain
that e-mails are delivered at all?). apart from that it can easily find out
that it does not host any mailbox in the domain "dna.affrc.go.jp"
i suggest you do also have a look at the other smtp related rfcs, especially
rfc821 (smtp) and rfc 1891 (smtp service extensions) ...
