How Does Email Works???

IMAP (INTERNET MESSAGE ACCESS PROTOCOL)

- to work with email from multiple computers
- messages are displayed on local computers and stored on the email server
  = you can work with all your mail, old and new, from any computer connected to the Internet, as            long as the mail servers are running

HTTP (HYPERTEXT TRANSFER PROTOCOL)

- allowing mail to be delivered in a web page format

BOUNCED BACK EMAIL ⇨ bad user account name
                                              ⇨ bad domain name
                                              ⇨ domain name server is down for several days
                                              ⇨ some other malfunction (email is too big)

SPAM MAILS!!!
  • may contain disguised links leads to phishing websites or sites that are hosting malware
