I have just migrated my exchange environment from Exchange 2007 to 2010.
Everything seems working fine but I just hitted 2 issues which one I managed to resolved and one is still pending.
The problem is email from EDI software supposedly relay by new exchange server to our transport customers but it returns with
error " 550.5.7.1 UNABLE TO RELAY FOR DOMAIN"
I have created a separate smtp relay connector with no authentication and anonymous permission
Relay for other IPs are working fine. But the relay for the EDI software with IP address 192.168.11.112/32 is not works.
It return with the error message as below
start 12:55:44
Trying to connect to server: 10.100.2.81
Communication to the server successfully
EDI message sending… Wait
Transmit failed.
SMTP returned error: 550.5.7.1 Unable to Relay
So I created separate custom connector and added 192.168.11.112(EDI software computer IP address) to receive mail from server pane, with no authentication and with anonymous permission checked.
I am still waiting for the outcome from my helpdesk. Meantime would you able to correct me to setup the mail relay for my EDI software. Is there any other possibilities which the smtp server to throw the message.
Kindly guide me on how to check further and what I can do upon this issue?
Thanks
