Question

Suppose Alice uses an e-mail client on its PC to send an e-mail to Bob. Assume that neither Alice nor Bob uses a Web based e-mail client. List the series of application layer protocols that are used to move the message between the involved hosts/servers. (If you have multiple alternative protocols for a transfer task, just list one of them.)

Answer 1

Email Sender -> Alice
Email Receiver -> Bob

-> In the Application layer of the OSI model of data transfer over a network , SMTP (Simple Mail Transfer Protocol) is used to send and receive emails from the PC client.
-> Lets assume that the email client being used is Microsoft Outlook to easily relate and understand the process.
