What role does the SMTP server play in email communication?

1. It stores incoming emails

2. It sends outgoing emails

3. It retrieves emails

4. It forwards emails to other SMTP servers

The correct answer is: It sends outgoing emails

In email communication, the SMTP server is primarily responsible for sending outgoing emails. SMTP, which stands for Simple Mail Transfer Protocol, is the standard protocol used for transferring email messages from a client to a server or from one server to another. When a user sends an email, the SMTP server takes on the task of relaying that message to the recipient’s email server. Once the SMTP server receives the outgoing email, it processes the email's recipient information and routes it accordingly, ensuring that the message reaches its final destination. While it can handle other functions, its core role is to facilitate the sending of emails, making this answer the correct choice. Other options, while relevant to email systems, do not define the primary responsibility of the SMTP server in the communication process. For example, functions related to storing or retrieving emails are typically managed by other types of servers, such as POP3 or IMAP servers. Additionally, while SMTP servers can forward emails to other servers, the emphasis is primarily on the sending aspect rather than simply forwarding.
