Those are Read receipts. Are you accessing it as an IMAP account?
See http://www.slipstick.com/emo/2008/up081023.htm#4 - moving or deleting
items will trigger the warning, if you have outlook set to warn, but
emptying the junk mail folder doesn't appear to honor the setting. Marking
items read first will.

check "sent mail" folder form "gmail" account. There are many sent mail
in the following forms:
