The two network protocols that are typically used when sending and receiving Internet email are SMTP and POP3.
SMTP (Simple Mail Transfer Protocol) is a standard protocol used for sending email messages over the Internet. SMTP is used to transfer outgoing mail from a mail client, such as Microsoft Outlook, to a mail server, such as Gmail or Yahoo mail. Once the mail server receives the email, it then sends the email to the recipient's mail server using SMTP.
POP3 (Post Office Protocol version 3) is a protocol used to retrieve email messages from a mail server. POP3 is used by a mail client to connect to a mail server and download incoming email messages. Once the email messages are downloaded to the mail client, they are usually deleted from the mail server, unless the user configures the email client to leave a copy of the message on the server.
SNMP (Simple Network Management Protocol) is a protocol used to manage and monitor network devices such as routers, switches, and servers. It is not used for sending or receiving email.
DHCP (Dynamic Host Configuration Protocol) is a protocol used to assign IP addresses and other network configuration information to devices on a network. DHCP is not used for sending or receiving email.
ICMP (Internet Control Message Protocol) is a protocol used for network troubleshooting and diagnostics, such as ping and traceroute. ICMP is not used for sending or receiving email.
SFTP (Secure File Transfer Protocol) is a protocol used for securely transferring files over a network. SFTP is not used for sending or receiving email.
In conclusion, the two protocols that are typically used for sending and receiving Internet email are SMTP and POP3.
