What is an Email Client?
An email client is a program that helps you in sending and receiving emails. Emails are stored over an email server or Mail User Agent (MUA). The emails are downloaded from a folder the very instant the MUA connects to the email server via POP or IMAP. The very soon an email is sent, the email client connects it to the server using the SMTP protocol. Some of the famous email clients are Outlook, Windows Live Mail, etc. As an email client is just a program on your PC, therefore it saves emails in the form of files on your computer. The drawback of the email client is that it has a limitation of accessing emails just from a single system.
