Describe in brief how email system works
Following is a simple description of how email system works:
- Sender composes a message (and attaches a file if required) and sends it
- This message is sent to an ISP (Internet Service Provider) mail server
- Mail server examines address associated with message and decides how to route message
- Message travels over the internet arriving at recipient's ISP mail server
- Message is then held in the recipient's electronic mail box
- To read the message, recipient logs on to their mail server
- Message is then retrieved and sent to recipient's computer
