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.
