No problem about RSCS messages, I just wrote the mod:
 
28 Oct 1986 20:12:59 RSCS message: Location DSFS is not defined
 
 
  However the  Errors-to does default  to postmaster,  and there should  not be
any empty To:. If you can reproduce the error I'd appreciate a detailed explana
tion so I can find the bug and nail it to the wall :-)
