how to develop a mail server?

A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.

Web Servers

Java application servers that support the Java EE platform and features include JOnAS from Object Web, WildFly (formerly JBoss AS) from JBoss, Geronimo from Apache, TomEE from Apache, Resin Java Application Server from Caucho Technology, Blazix from Desiderata Software, Enhydra Server from Enhydra.org, and GlassFish from Oracle. Commercial Java app servers include WebLogic by Oracle, WebSphere from IBM and the open source JBoss Enterprise Application Platform (JBoss EAP) by Red Hat.

Java App Servers

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
