You will find the Sent From in the Edit screen for that account on the main screen, not the Advanced screen. Also, you don't need to worry about the server's SMTP address. When sending from a BIS configured email address on the BB, the BIS sends directly and not from your IMAP server.
If you can explain the details of the problem a bit better, maybe we can help.
