Standard Task not sending internet Mail to SAP User

Through Standard Task TS00007989(Outbound, error handling with IDoc) able to send workitems to SAP Inbox when an error occurs in IDOC, however would like to have these workitems sent as an internet mail , the email address would be in my userid in SAP.

Email address is already given in my userid with the communication method as INT E-mail.

Would like to have a solution for this as soon as possible.
