In Mail Essentials it would be great to have the option to block by SMTP from as well as Mime from on the blacklist. it would make a great addition to be able to block all the *@*.ru messages that claim to be from yahoo.0 votes
Actually it's not possible to reject messages considered as spam, you can only "delete", generate NDR, deliver to inbox/junk, tag e-mail. I dont want to generate NDR because they are bandwith consuming; "reject" consumes less server resources as you don´t have to process the entire email, no data is received. All other Anti-Spam products (and Exchange Server itself) permit to do this kind of action.0 votes
