thanks eliekarkafy I can block the attachments internally no issues. My rule blocks my internall attachments and allows external attachemtns. My company want to be able to block all internal attachments unless they include and external address. So I need the the rule to block all internal attachment unless there is a external address. Then the attachment needs to be delivered to both. Internal and External.
