From the developer: "RelayFax is a powerful fax server with OCR and TWAIN capability. It turns all your modems into fax machines. Incoming faxes are routed to the correct people via email by user-defined 'rules' which are powerful and flexible. You can route incoming faxes by a variety of criteria including OCR, Caller- ID, fax device, etc. RelayFax includes printer drivers which allow you to fax directly from any application that can print. Outgoing faxes can also be routed based on rules. RelayFax collects emails from your mail server and turns them into outgoing faxes. To send a fax you simply email RelayFax with the details and attach your documents. RelayFax will turn your DOC or XLS files into faxable images and send them on their way. RelayFax pays for itself by increasing the productivity of your workers."
