Hello All,
I have deployed Exchange server 2016 cluster setup recently and since i have created a anonymous relay on Exchange servers which i found a vulnerability for the organization.
I followed below article to enable the anonymous relay:
https://technet.microsoft.com/en-us/library/mt668454%28v=exchg.160%29.aspx?f=255&MSPPError=-2147217396
However, I need to disable this open relay and create a dedicated receive connector to allow specific IP's to send emails.
Kindly advice me to remove the open relay where all the users can relay emails where it has become a major threat.
Appreciate your prompt response.
Thanks and Regards,
Dilshan
