VZW MMS issue. Message Expired

[QLicious]

Anybody else having an issue where you send a MMS picture message to another person (Not on your network) and hours if not days later it comes back and says "The message you sent to 'xxxx xxxxx' then <phone number> has not been delivered, the message has expired."

What does this mean?

I'm able to send and receive from other verizon users, but when I send to like US Cellular or Cingular I get this.

Anybody have an idea?

Or any idea how to turn off the notification? It comes back like I have a new MMS, so I go and look and it's an MMS reply saying it's expired. completly annoying.

isn't it like with e-mails... it tries to send for a x amount of time and when that fails it sends the original sender the notification that it gave up trying..
