Dear All kindly help me out. i m using Microsoft Exchange 2010. Due to some configuration i am facing that issue.
I am unable to send email from other domains. My exchange server reject that email with this message.
Remote Server returned '530 5.7.1 Client was not authenticated'
if i check the option of anonymous in receive connector then it will also not asking authentication from my domain users.
therefore i unchecked the anonymous option. But now i am unable to get emails from other domains.
Kindly give me any solution i will be very thankful.
