Create users and authorized email addresses to fax by email under single account 2.) delete user account or authorized users Please note ONLY SIP modems will be used. Deliverables: The project will be provided via a scriptable install or text file with details on how to install. We will be using a REALY server (not virtual) using CentOS 6.4 x64 minimal. Please base your install scripts to match that requirement. For email, we will be using our email server / relay. This server does not sit on the edge network but behind a firewall. It will retrieve emails for faxes through an imap account and sent through imap or smtp relay.
