I am interested in learning how to only send to or NOT send to certain domains in a campaign or on the campaign level? I swear i saw this when setting up but cant seem to find it anywhere now? Ive been looking for hours.
I can now answer my own question. I found the solution while adding a new server. This can be done on the server setup area... When added a delivery server the option is midway on the page to add rules for domains etc.
