Email-Client

Emails are used for the purpose of communication and can be sent from command line using sendmail command, mail command, mutt command, SSMTP command and telnet command. Among these commands, sendmail is the most commonly used email routing command, which supports SMTP (Simple Mail Transfer Protocol) for the transport of emails across the internet. Yahoo, Gmail and RediffMail are some of the email service providers, which act as web interfaces that send and receive emails.
