SMS format and DSN: Data format error

[Lowery, Michael]

I'm having problems getting mail messages to my phone.  I can send them
manually, but was under the impression that I should use the
"FORMAT=SMS" option to send to my phone since it has <160 characters
allowed.  

When sending, I get the "DSN: Data format error" from the mail server at
my cell company.  Do I have to have a script written for this to work,
or should it work as I have it configured?

Here is the only entry in hobbit that I have configured that has
anything to do with this message being sent.  Any help would be
appreciated!

Hobbit v4.0.2
