Emailing

Emailing is a way of communicating with another person via the internet, it is very different from instant messaging in that it is used for more formal situations. When typing an email, the user is provided with an opinion of who will receive the message,

How do Emails Work?

  1. The sender composes a message using the email client on their computer.
  2. When the user sends the message, the email text and attachments are uploaded to the SMTP (Simple Mail Transfer Protocol) server as outgoing mail.
  3. All outgoing messages wait in the outgoing mail queue while the SMTP server communicates with the DNS (Domain Name Server–like a phone book for domain names and server IP addresses) to find out where the recipient’s email server is located. If the SMTP server finds the recipient’s email server,  it will transfer the message and attachments. If the recipient’s server can’t be found, the sender will get a “Mail Failure” notification in their inbox.
