Lesson 1

The email program that was issued for the version of Red Hat Linux released in the year 2002 was Evolution. Evolution is a free and open-source email client, personal information manager, and groupware client developed by the GNOME project. It was first released in 2000, and it is currently one of the most popular email clients for Linux. Evolution was included in the default installation of Red Hat Linux 7.3, which was released in 2002. It replaced the previous email client for Red Hat Linux, which was called Pine. Evolution is a more modern and feature-rich email client than Pine, and it has been well-received by users.
Here are some of the features of Evolution:

1. Email: Evolution can send and receive email messages, and it supports a variety of email protocols, including IMAP, POP3, and SMTP.
2. Calendar: Evolution can be used to manage your calendar, and it supports a variety of calendar formats, including iCalendar and vCalendar.
3. Contacts: Evolution can be used to manage your contacts, and it supports a variety of contact formats, including vCard and LDAP.
4. Tasks: Evolution can be used to manage your tasks, and it supports a variety of task formats, including iCalendar and vCalendar.
5. Notes: Evolution can be used to take notes, and it supports a variety of note formats, including plain text and HTML.

Evolution is a powerful and versatile email client that is a great choice for users of Red Hat Linux. It is easy to use, and it supports a wide range of features. If you are looking for an email client for your Red Hat Linux system, then Evolution is a great option.

The current version of Red Hat Enterprise Linux (RHEL) does not ship with a graphical email client like Evolution by default. Instead, Red Hat focuses on providing command-line tools and server-side components for email. For email handling, RHEL includes:

• Mail Transfer Agents (MTAs) like Postfix and Sendmail.
• Mail Delivery Agents (MDAs) like Dovecot for IMAP and POP3 services.

However, if you're looking for graphical email clients recommended or supported by Red Hat, they often suggest using external, open-source clients that can be easily installed. Among the popular ones, you can find:

• Evolution: While not shipped by default, it can be installed on RHEL from the repositories. It remains a well-supported choice for those needing a full-featured email client.
• Thunderbird: Another popular open-source email client which can be installed on RHEL systems.

For the most current and accurate recommendation, checking Red Hat's official documentation or support articles would be beneficial, as the exact software included or recommended can change with updates and new releases. In the year 2024, Evolution isn't part of the default installation but is available for installation.

Internet email is as pervasive as the World Wide Web. Almost everyone on the Internet has an email address. Consequently, there is a high demand for email, which requires a substantial infrastructure to maintain.
Most of the Internet's email capability comes from UNIX-like systems running specialized email handling programs. This module introduces you to the Linux versions of these programs, classifying them and describing their individual purposes. Also, you will learn about SPAM^[1], and how Linux systems combat this problem.

After completing this module, you will be able to:

1. Explain how the Internet transfers email
2. Define the roles of the three email system agents
3. Describe the purpose of Linux's MTAs and MDAs
4. Describe the purpose of Linux's MUAs
5. Identify the traits of email SPAM
6. List tools that combat email SPAM

The next lesson explains how the Internet transfers email.
