SAP EM - SMS Alert

Hi,

I am trying to configure SAP EM Alert using SMS just like Email Alert.

I have configured SCOT - SMTP

I have configured it as

SMTP - Mail Server

added IP details for Mail host & Mail Port

under supported address type for pager (SMS) i have set the address area as '*' and defined the domain in "conversion into internet address"

I have not done the mapping in SICF - proxy details.

I have received following error

Cannot process message in SAP System

Message no. XS817

Diagnosis

Processing could not be continued due to a technical or configuration error in the SAP system.

System Response

Processing was terminated.

Procedure

Processing was terminated in the SAP system. The reason is given in the details below:

Received e-Mail address SMS=+XXXXXXXXXX@SMS=+91XXX

Please suggest what i need to change.
