Question

Suppose that Ahsan wants to send an email message to Mahfuz. This will involve four entities: Ahsan’s mail client, Ahsan’s outgoing mail server, Mahfuz’s incoming mail server, and Mahfuz’s mail client. Draw a diagram with these entities and explain the flow of the e-mail message from Ahsan’s client to Mahfuz’s client. You must mention the names of the protocols used in this process.

a) True

b) False

Answer 1

True (Option a)

Step-by-step explanation:

The process of sending an email from Ahsan's mail client to Mahfuz's mail client involves several steps and entities. Ahsan's mail client initiates the email composition, which is then sent to Ahsan's outgoing mail server (SMTP - Simple Mail Transfer Protocol). The outgoing mail server processes the email and communicates with Mahfuz's incoming mail server through SMTP or POP3/IMAP protocols.

Once Mahfuz's incoming mail server receives the email, it stores it until Mahfuz's mail client retrieves it. Mahfuz's mail client connects to Mahfuz's incoming mail server using protocols like POP3 (Post Office Protocol) or IMAP (Internet Message Access Protocol) to retrieve the email.

In summary, the flow of the email message starts from Ahsan's mail client, goes through Ahsan's outgoing mail server using SMTP, is transmitted to Mahfuz's incoming mail server using SMTP or POP3/IMAP protocols, and finally reaches Mahfuz's mail client using POP3 or IMAP for retrieval.
