_Any_ client does that, thus the search is restricted to windows clients that support IMAP (Thunderbird is a relatively good one.) It seems the user's client was in offline mode, automatically reconnecting at given intervals to send/receive all mail. The failed recipient was probably local at the outgoing mail server, thus the client knew that a recipient failed and didn't move the message from "outgoing" to "sent" mail, even if it sent the message to the valid recipients. If that's the newest client version, and its developers have a (free) bug list, filing a bug at theirs would be appropriate. To elucidate the issue, it may help to know that MTAs maintain separate control files where they mark the delivery status of each recipient. A MUA wouldn't be able to do the same without altering the original message (unless it uses control files as well.) As a possible workaround, Courier is able to send messages from a special IMAP folder.
