Correct Answer:

Explanation (300 words):
In electronic mail systems, a user agent (UA)—also known as an email client—is a software application that enables users to interact with their email. It serves as the interface between the user and the underlying mail system. The user agent performs several essential tasks to facilitate email communication efficiently.
1. Composing Messages:
The user agent allows users to create or compose new messages. It provides fields to enter the recipient’s email address, subject line, message body, and attachments. Once composed, the message is passed to the mail transfer agent (MTA) for delivery.
2. Reading Messages:
The UA retrieves emails from the mail server using protocols like POP3 or IMAP. It displays the content in a user-friendly format, allowing users to read the subject, sender information, and body of each email.
3. Replying and Forwarding:
Users can respond to received messages using the reply or reply-all functions. The forward option allows users to send a copy of an email to another recipient. The user agent simplifies this process by automatically including the original message and headers.
4. Organizing Messages:
The user agent lets users manage their inbox using folders or labels. Users can sort messages by date, sender, or subject, delete unwanted mail, and mark important ones. Some email clients also support filters and rules to automate email sorting.
5. Managing Attachments:
The user agent allows users to attach files to outgoing emails and download or view attachments in incoming ones.
6. Address Book Management:
Many user agents include a contact or address book, storing frequently used email addresses for quick access.
By providing these functionalities, the user agent greatly enhances the usability of email systems and ensures smooth communication between individuals and organizations.
