I am new to exchange, please forgive my stupid question and poor English!
I have an exchange 2000 server installed. I want to let outside people send
mail though my exchange 2000 Server with authentication.
Actually, outside people can send mail though my exchange server when
authentication of "SMTP Virtual Server" set to "anonymous access".
I got an error message "Server respone :4220.127.116.11 client does not have
permission to send as this sender" when "anonymous access" disabled.
Does anyone tell me what should I do to make the authentication success or
there are another method to acheive it.
Thanks you for all replies!
