Email Application

First of all, we must know what is email application.
Email application is an application that runs on a personal computer or workstation and enables you to send, receive and organize e-mail. It's called a client because e-mail systems are based on a client-server architecture. Mail is sent from many clients to a central server, which re-routes the mail to its intended destination.

Before you launch an email client, you need information from your Internet Service Provider (ISP) to configure the client properly. The following is a list of important configuration information:

Your email address:

The email address you use to send and receive mail. This is usually in the form of <yourname>@<example.com>. In this example, <yourname> is your user name and <example.com> is the domain name for your ISP.

Server type for receiving email:

In order to receive mail, you must know what type of server the ISP is using, POP or IMAP.
POP, short for Post Office Protocol, is used to send email from a mail server to your email client's inbox, the place where incoming email is stored. Most ISP email servers use the POP protocol, although some use the newer IMAP protocol. POP mail is downloaded to your email client directly and does not stay on the server by default (although most email clients can be configured to leave email on the server as well).
IMAP, short for Internet Message Access Protocol, is a protocol for retrieving email messages from your ISP's email server. IMAP differs from POP in that email from IMAP servers are stored on the server and not downloaded to the mail client.

Address for receiving email

In order to receive mail, you must obtain the address of the POP or IMAP server from your ISP. This address is usually in the form of mail.example.com.

Server type for sending email (SMTP)

The Simple Mail Transfer Protocol (SMTP) is a protocol for sending email messages between mail servers. Most email systems use SMTP to send messages over the Internet; the messages can then be retrieved with an email client using either POP or IMAP. SMTP is also used to send messages from a mail client to a mail server. This is why you need to specify both the POP or IMAP server and the SMTP server when configuring an email application.
