Outbound Server Error

Unable to send outbound email traffic through a Samsung
i600 on a Smart Phone 2002 O/S.

Received following text error message:
"The message(s) could not be sent. Verify that you have
network coverage and that your account information is
correctand then try again"

Question (1), Should we install Mobile Information Server
on our server to send outbound email?

Question (2), Should we select server authentic in the
Smart Phone 2002 menu option for sending outbound email
through a Windows 2003 Server?

Question (3), What list of ISPs support Smart Phone 2002
outbound email traffic?
