I think you're confusing two things here: That To: line is part of the message itself (sent among the mail headers after the "DATA" SMTP command), while RCPT TO: is another thing (before the DATA state of the SMTP transaction), it's not even compulsory that these two things contain the same address ... Just think about mail forwarding and so on. I don't think it's possible to give "name" before the address at the RCPT TO command and it's also useless, do that in the mail itself. This was AFAIK/IMHO :)
