How do I get the message once I've sent it?

[paritycheck]

Hi guys, I need to get a way to get a message I've sent from the compose page once it has been sent. Is there any way to retrieve a message from its message ID or is there any way to retrieve the newly generated UID of the message once it has been sent... Any help would be greatly appreciated.

PS I need to set up the new message in the BasicHeader class form as in the imap.inc file.

Actually what I mean is that I need to get the UID atleast of the message once I have sent it so that I may be able to download the saved message from the mail server and save it to my db... for I cant seem to find anyway to track an email once it has been composed and sent apart form going to the sent box and retrieving it from there.
