Hello Expert,
Any other option to be enable looks like I need to do some configuration in email server. If I don't set any authentication in email receiver I am getting the below error.
Message processing failed. Cause: com.sap.aii.af.sdk.xi.srt.BubbleException: Failed to call the endpoint [null "null"]; nested exception caused by: java.io.IOException: server not responding OK to RCPT TO; 550 5.7.1 Unable to relay
But for the same mail server I could able to send external mail from ECC server. Kindly advice.
Thanks,
Dhill
