Holy cow Batman can you say progress?!  Discovered this by accident
just yesterday.

Cingular has made a subtle yet important improvement in their text
messaging services (SMS/MMS).  If you send a message to an invalid
email address, you now receive notification of the delivery failure!

As you probably know, text messenging allows you to send short messages
directly to another person's phone.  It's also the underlying service
that's used when paging someones cell phone.  What you may not have
known is SMS/MMS can gateway to the Internet and send messages to an
email address.   It requires special syntax in the message, but by
using text messaging to send email, you can forego purchasing your
wireless carrier's email service.

In the past, the only downside to using text messaging for this purpose
was lack of delivery failure notices.  So, you never really knew if
your message was delivered or not.  Now, you do.  It's great news for
those of us who like a little certainty with our technology.
