Unable to send mail through Exhcange server 2K!!!
Posted on 2005-04-21
My test network at home consists of a XP workstation, 2003 Domain Controller and Exchange Server. I have communication between all 3 machines. I'm able to receive domain mail and my POP3 mail but I'm unable to send any mail.
I'm trying to send my mail "through" my Exchange server rather than directly to my ISP, thus the "test network".
This is the latest error message I got when I tried sending to a yahoo email.
The message cannot be delivered due to a configuration error on the server. Please contact your Administrator.
<exchangeserver.Babylon.local #5.3.0 smtp;553 5.3.0 flpvm21,DNSBL:
I get this or a similiar error no matter where I try to email too. If I send directly from the workstation to my ISP, no problem.
thanks in advance....
