downtick,
This has been discussed a lot lately on a couple threads. You really should search before posting, especially before opening a new thread.
Sprint seems to have been fooling with its DNS servers for picture mail, so you need to enter numerical IP address in the configuration rather than a URL. I don't know which it is since I don't use Sprint. Should be in a thread on the first 1-2 pages of the Apache or Apache Upgrade forum....
