It appears the system is temporarily configured whereby the Vax and Alpha machines are working in parallel. The effect appears to be that some messages reach UNIX, some go to the old RLSAC (as yet not switched off) and a few bounce back to the sender. The correct INTERNET addresses for Rutherford and Cambridge are: GMH at AST.STAR.RL.AC.UK (Rutherford) GMH at AST-STAR.CAM.AC.UK (Cambridge) It is recommended for the time being that important messages eg discovery reports are copied to both sites,
