Email Management is the Next Big Aspect of Cloud Computing, a system that we are carrying for past 30 years, maybe their use has changed, has been intensified. As one person wrote many a decades ago - Technology changes but the basic pattern remains the same. Rackspace Cloud basically uses Free Softwares including Open Stack but uses Microsoft’s product for Email Management. The reason is nothing but, as the Email Management basically has remained the same old way Microsoft essentially delivered as Software as a Service when there was no Cloud Computing, it has been easier for Rackspace to use it. But the fact is – it is basically the old way of Email management.
