Problems with this email process quickly became evident as the construction company encountered poor performance, increased costs from unnecessary bandwidth use, reliability and speed issues, and security concerns over the possible exposure of sensitive data. With these issues in mind and the desire to be able to maintain the systems inhouse, the IT department decided to perform a review to establish potential alternatives. After performing an initial assessment to ensure that the migration would not affect the existing production IT systems, eComputers installed a server running Red Hat Enterprise Linux to handle Arabtec's mail system. Red Hat Enterprise Linux currently runs on the email server in Arabtec's head office, as well as the DNS, proxy, and firewall servers in the company's remote sites.
