Ok I’m running exchange 2003 on windows 2003 server I have SMTP setup i would like to allow users to relay email but I want to enable outgoing authentication when using outlook and disable anonymous.  I think I already have done that but it seems i can still replay email with out authenticating can someone tell me the procedure to set this up thanks.

    Hi adpro,
    Go to your Exchange System Manager>Administrative Groups>Servers>NameOfServer>Protocols>Smtp>Now right click what is (probably)Default SMTP Server and hit PROPERTIES> Click the Access tab> Click on Authentication. Here make sure "Only the List below" is selected and then put a checkmark in "Allow all computers which successfully authenticate with this server..." This should work fine. Of course in outlook you need to change the settings for "outgoing server" which seems like you have done. Hope this helps.

    Well that didnt seem to do it let me explain.  ok so lets say my exchange server sends emails as,  ok so now from my outlook in order for me to be able to send emails via the smtp server on that exchange box all i have to do it seems is to make the outlook "email address" field have a value of i dont have to turn on outgoing authentication also take into consideration that my incoming server information is not at all the right information for loging into that exchange box.  If i enter a value in outlook's email address field with it does not allow me to send.
