As of right now, in order to prevent e-mails from being received from a domaine, you must copy the domain, click on Settings, then click on More Settings, click on Security, click on option to add a domain to block, paste the domaine in the field, and then click the opttion to block the domain. If you have many domains to block this takes a lot of time. May I suggest a macro or option be created so that all a user needs to do is right-click on the unwanted e-mail and selece a "Block Domain" optiion? Please investigate if t his wouild be possible. Thank you.
