  Thanks for reply

  My users are receiving emails properly. Some of them are Internet users and 
some are only local users, but I can send email internally from anybody's 
account w/o authentication through telnet.
  Is it correct?

    Hi

    I am using exchange 2003 Exchange server in Front end/back end
    enviorment .

    When I am doing SMTP test with telnet to my server,It works well with
    outside user,means it is not allowing to send email to outside world.
    But it is allowing to send email in my domain from any user to any user
    .
    How can I provide authentication for sending mail ?

    Is it an open relay ?

    I know it is not on internet, but it is on internal network.

    how can I stop this?

    Please help me

    The haggis is unusual in that it is neither consistently nocturnal nor 
diurnal, but instead is active at dawn and dusk (crepuscular), with occasional 
forays forth during the day and night.
