Hi averyone.
I'm testing Exchange Server 2003. Incoming mail and internal is working fine. But, sending mail out is not working.
This is the error that I'm getting:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'xxxxxxxxx@yahoo.com'. Subject 'test', Account: 'xxxx.xxxxxxxxxxxx.org', Server: 'xxxx.xxxxxxxxxxxx.org', Protocol: SMTP, Server Response: '550 5.7.1 Unable to relay for xxxxxxxxx@yahoo.com', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
Could someone give me some pointers, where could be the problem, or how the the smtp should be setup?
Thank you.
