What is iMail?
iMail is an enterprise-class email server does Microsoft Exchange and Gmail work at same time. It consists of an internal email system and an external email system. The internal mail system is similar to Microsoft Exchange, and the external mail system is similar to Exchange Online or Gmail. It is simple in structure, efficient, and almost free. In addition, iMail can process internal mail and external mail at same time at one place so that whether inside or outside the company, users can send and receive both internal and external mail via computer and mobile devices.
Unlike Exchange Online, Gmail and other web email services – the email data must be store on their cloud, iMail server is self-hosted server. iMail stores all email data at your owned area, usually just in your office. We believe save company internal email data at public area or the area that you don’t own is not acceptable for many reasons, the mainly are security and speed. Public (external) email system and company internal email system should be separated. For example, you should not allow your employees send company data to public email addresses such as abc@hotmail.com or xyz@gmail.com etc. via company internal email system.
iMail system is most economical because iMail is almost free, the price is less than one percent of Microsoft Exchange. “Wondering how an 800-employee company spends a million dollars a year running its email servers?” see Phil Wainewright‘s report here http://www.zdnet.com/article/how-much-does-exchange-really-cost/, it is $1250/user/year.
iMail system setup is easy. You don’t have to install and setup all kinds of Windows servers. iMail systems only need one Windows 8.1/10 computer. And unlike Microsoft Exchange install Outlook on each client computer, iMail is complete web-based access, a web browser will do on client side. So. iMail doesn’t need install any software on client computer, a web browser is enough. iMail has been test on IE, Chrome or Firefox.
Setup iMail is very simple. Compare with the Microsoft Exchange setup, you need hundreds of hours to learn and prepare, setup iMail system is very easy. One-key install Sanwhole Exchange on a Windows 8.1/10 computer, your local iMail Server is okay. Nothing installation required on your users’ computers. So, watch several tutorial videos you will master iMail System.
