Email Server
An email server is also known as a mail server. It works
very much like a post office in a virtual network. It consists of a
storage area and holds email for users connected to the network.
An email server is a database that responds to definable rules and
commands. These commands determine how the server should work. The commands
let the server know how to react to mail marked with specific addresses
and extensions. It also suggests when mail should be transferred to
other mail servers.
The person responsible for maintaining an email server is often called
the postmaster. Generally mail servers function without any manual intervention.
However, servers have been known to crash and the postmaster must be
ready to intervene. In addition, the postmaster sets rules to eliminate
spam and deal with expired accounts.
