Overview of Electronic Mail (Email)
- Email is a widely used communication medium that transmits and receives messages using electronic devices.
- Email operates across computer networks, primarily the Internet, and also local area networks.
- Originally an ASCII text-only communications medium, Internet email was extended by Multipurpose Internet Mail Extensions (MIME) to carry text in other character sets and multimedia content attachments.
- The term electronic mail has been in use with its modern meaning since 1975, and variations of the shorter E-mail have been in use since 1979.
- Computer-based messaging between users of the same system became possible after the advent of time-sharing in the early 1960s.
- The Simple Mail Transfer Protocol (SMTP) protocol was implemented on the ARPANET in 1983.
- Email messages consist of two sections, "header" and "body".
- Email clients may allow hiding read emails from the inbox so the user can focus on the unread.
- Many current email users do not run MTA, MDA or MUA programs themselves, but use a web-based email platform, such as Gmail or Yahoo! Mail.
- The Post Office Protocol 3 (POP3) is a mail access protocol used by a client application to read messages from the mail server.
- The Internet Message Access Protocol (IMAP) provides features to manage a mailbox from multiple devices.
- Messaging Application Programming Interface (MAPI) is used by Microsoft Outlook to communicate to Microsoft Exchange Server.The Uses, Issues, and Internationalization of Email
- Email is widely accepted by businesses, governments, and NGOs, with 83% of U.S. knowledge workers feeling email is critical to their success and productivity at work.
- It is used for email marketing via "opt-in" to send special sales offerings and new product information.
- Email is accessed via personal computers, smartphones, and all types of computers.
- Alerts can be sent to smartphones or other devices to notify users of new messages.
- As of 2011, there were approximately 1.4 billion email users worldwide and 50 billion non-spam emails sent daily.
- Email messages may have size limitations due to email clients, servers, and ISPs, which can lead to confusion for senders.
- The ubiquity of email has led to concerns of "information overload" for recipients and can lead to increased stress and decreased satisfaction with work.
- Email spam is unsolicited bulk email, which can threaten the usefulness of email as a practical tool.
- A range of malicious email types exist, including email scams, phishing, email bombardment, and email worms.
- Email spoofing occurs when the email message header is designed to make the message appear to come from a known or trusted source.
- Email bombing is the intentional sending of large volumes of messages to a target address, which can render it unusable and cause the mail server to crash.
- Email privacy can be compromised if security precautions are not taken.
- Originally, Internet email was completely ASCII text-based, but MIME now allows body content text and some header content text in international character sets.
- The original SMTP mail service provides limited mechanisms for tracking a transmitted message, and none for verifying that it has been delivered or read.
- Many ISPs now deliberately disable non-delivery reports (NDRs) and delivery receipts due to the activities of spammers.
- In the absence of standard methods, a range of systems based around the use of web bugs have been developed.
