I have been asked to block emails coming to our Exchange 2013 SP1 server from outside our organizations from specific email address. In my case here I’m using ‘firstname.lastname@example.org’ as an example.
In Exchange Admin center (EAC) I have created new mail flow rule with following conditions:
Block email from ‘email@example.com’ if the message...Is received from 'Outside the organization' and sender's specified properties match these text patterns: 'Email: firstname.lastname@example.org'
Do the following...reject the message and include the explanation 'Sender rejected' and Stop processing more rules
Well, something is not setup right because we’re still receiving emails from ‘email@example.com’ Perhaps I’m not digging in the right spot here… Maybe something else needs to be setup?!
Thanks in advance.
