A virtual mail server is good at load balancing and has many more benefits. When a Mail server is implemented on the hypervisor, it is then considered as a virtual mail server.

Although large ISPs and public email services have their dedicated hardware, in most cases, the web servers and mail servers are hosted on a single machine by virtualization. A computer system that sends and also receives an email over a network either on LAN or the internet is called a Mail Server. The 3 different type-2 hypervisor software we chose to compare were Kernel-based Virtual Machine (KVM), Oracle VirtualBox, and VMware. This work compares the virtual mail server performance on 3 different Hypervisor software.

With the help of virtualization, we can achieve benefits like reduced capital and operating costs, minimized downtime, increased productivity, and good disaster recovery, etc. Virtualization is a technology that will efficiently allow the instructions or programs based on the available hardware. Virtualization is now the most efficient and successful procedure to use server resources.
