20130346509 | Digital postal mail gateway - A digital postal mail connector (or “gateway”) is supported within an enterprise's (a mailer's) digital delivery infrastructure, preferably as a rack-mounted hardware appliance or software install. The digital postal mail gateway interfaces with the mailer's existing print process (e.g., a print stream processor) to automatically create an alternative output stream that is sent as one or more digital files and received online by the mailer's customers in web-based electronic mailboxes. | 12-26-2013 |
