I have a problem with autehtications on SMTP virtual server. I don't can to resolve this issue.
There is a relay restrictions section under SMTP virtual Server properties. Right now I am allowing "all computers which successfully
authenticate to relay". But Under authentication tab, I have enabled
"Anonymous access" "Basic authentication" and "Intergrated Windows
authentication".
When we try to send an email message, we are not able to send the mail. the error reported is
"Error: 8004020e. Description: The server rejected the sender address. The server response was: 454 5.7.3 Client does not have permission to submit mail to this server.

Why??? if i checked "all computers which successfully
authenticate to relay"

My users are connected by POP3 in outlook 2003, my exchange server is Win2003 and Exchange 2003, no more applications.

Any help regarding the same would be greatly appreciated. Thank You in advance
