Study Notes

Email Communication

Email is a digital communication method using electronic devices and computer networks.
Email exists since the 1970s, developed from ARPANET.
Email is popular due to widespread use of email client software (e.g., Outlook) and web browsers (e.g., Gmail).

How Email Works

Email messages travel through multiple servers to reach the recipient's server.
SMTP (Simple Mail Transfer Protocol) is used for transferring messages.
SMTP checks the recipient's email address and converts domain names to IP addresses using DNS.
MX (Mail Exchange) server is used to forward email to the recipient's server.
Emails are stored on recipients' servers and accessed using POP (Post Office Protocol) or IMAP (Internet Message Access Protocol).
POP downloads email to the recipient's device and deletes it from the server; IMAP stores email on the client enabling access from any device.

Parts of an Email

Email consists of an SMTP envelope, a header, and a body.
SMTP envelope contains sender and recipient email addresses; it's used for delivery and is discarded after transfer.
Header contains information like date, from, to, and subject; it may include optional information, useful for replying, forwarding, categorization, archiving.
Email header fields may include date (mandatory), from (mandatory), to, and subject.
