Audiovox CDM-9900

I've tried now to send both a picture & a .mid file to myphonenumber@vzwpix.com from my work email address. A message comes through but when I try to retrieve it I get Network Authentication Failed. I know there have been some problems with the network, but I just want to verify if it's a network problem or something else. I haven't seen anyone else post this particular problem yet.
