If you are sending the email through mailing list software (eg, courier-mlm) then the mailing list software will automatically handle the failed recipient without further interaction of the original sender. If you are sending the email from an email client (Outlook, Thunderbird, et. al.) then it's the users responsibility to remove the failed recipient from their list, AND to remove the email out of their outbox (because most email clients will consider any failure message as meaning that the email wasn't sent to any recipient, and will keep re-trying).
It's not called "SMTP" for no reason - the "S" is for SIMPLE, and the obligation is on the client in an SMTP transaction to deal with any error messages from the server.
