okay this is kinda strange
übercart isnt sending me any mails out at all?
but offcourse Drupal is sending mail (checked with the contact module)
if I go to admin/store/orders/*NID*/invoice/mail and tries to send out the invoise i get the "E-mail failed." information.
any one ever experienced that?

. it's occur because i typed my free email address not my true email that connect with smtp.., Thanks a lot Ryan..
