Created Unassigned: Sending a mail by creating a message in outbox [17443]

I can create a mail in outbox, set the "to" address but "submit" message doesn't do anything.

When I open outlook after I close mfcmapi, outlook sends the message from outbox. Is there a way for the outbox message to the spooler?

Is it possible to send a email from mfcmapi?

(Fundamentally I am looking for a client application which can send message using MAPI. IMessage::SubmitMessage just puts the message into Outbox)
