Hello,
I am trying to use the PMG as internal mail relay for our O365(exchange online), i did the setup and it works.
My dilema is how do i filter emails authorization only to the hosts in place on the whitelist. It seems that by default it's relaying everything, so i would like to stop doing that, and allow only the IP sources or networks that i whitelist ( and more precisely, where needs to be whitelisted ? on the configuration - mail proxy - whitelist , or Mail Filter - who objects )
Reject unknown clients is set to Yes
So in short i want to allow only specific IP's to relay mails via PMG, how can i do that.
Thank you in advance for any help ( i have searched the forum, and i did not find something similar with my case )
