Understanding Mailx: A Comprehensive Guide

What is Mailx?

Mailx is a powerful command-line email client found in Unix and Unix-like operating systems. It is an enhanced version of the original mail program, offering more features and flexibility for managing emails directly from the terminal.

Features of Mailx

• SMTP and POP3 Support: Mailx supports both sending emails via SMTP (Simple Mail Transfer Protocol) and retrieving emails using POP3 (Post Office Protocol).
• Attachments: Users can easily send attachments with a simple command, providing functionalities to handle files effectively.
• Mail Aliases: Mailx allows users to create mail aliases for easier email management and organization.
• Mailbox Management: Mailx can manage multiple mailboxes, enabling users to read, compose, and organize emails effectively.
• Search Capabilities: It offers powerful search options to find emails based on various criteria like sender, subject, and date.

Installation

To install Mailx, you can use your system's package manager. For example:

sudo apt-get install mailutils   # For Debian-based systems
sudo yum install mailx               # For Red Hat-based systems

Basic Usage

Sending an Email

To send an email using Mailx, the basic syntax is:

echo "This is the body of the email" | mail -s "Subject of the Email" [email protected]

In this command, -s indicates the subject of the email, and the recipient’s email address follows it.

Reading Emails

To read emails, simply type:

mail

This will display a list of your emails. You can use the number in front of the email to read a specific message. To delete a message, use the d command followed by the message number.

Replying to Emails

To reply to an email you are currently viewing, use:

reply

This will open a new mail editor with the original message quoted.

Advanced Features

Configuring Mailx with SMTP

If you need to send emails through a specific SMTP server, configure the following settings in the .mailrc file:

set smtp=smtp.example.com
set smtp-auth=login
set smtp-auth-user=username
set smtp-auth-password=password
set from="[email protected]"

Email Aliases

To create an alias, add the following line to the .mailrc file:

alias name "[email protected]"

Now you can use name to send emails to [email protected].
