Runtime Dump solution required

Question

when running the program in background it gives short dump at a remote function call(CALL FUNCTION 'RFC_MAIL'
              DESTINATION 'CC_MAIL'
       EXPORTING
          USER = E_MAIL_USERS-UNAME
       TABLES
          MAIL = MAIL_TAB .)
It was logged under the name "RFC_EXTERNAL_ABORT"
on the called page.
what happended : ("mail terminated with exit code 256 (Command not found ?)."
The current ABAP/4 program had to be terminated because
of the above FM statements could not be executed.
This is probably due to an error in the ABAP/4 program.
The error occurred in an RFC call to another system.
The target system has also written a short dump.
where is the change required ? and what is the exact problem..?
thanx in advance.
Regards
Ashok
