Mailing protocols define the methods by which programs send and receive email through the Internet. Research mailing protocols and give details about any three of them.

Three mailing protocols are as follows:

Simple Mail Transfer Protocol (SMTP): This protocol exchanges email among servers. Most email systems that use the Internet use SMTP to transmit messages between servers. Email clients receive messages from these servers using either the Internet Message Access Protocol (IMAP) or the Post Office Protocol (POP). SMTP transmits messages from a mail client to a mail server.

Post Office Protocol (POP): This protocol fetches mail from mail servers. Most email clients (or email applications) receive mail from mail servers using POP in one of two versions: POP2 and POP3. POP2 was the standard mailing protocol that email clients used along with SMTP in the 1980s. Email clients can use the latest version, POP3, with or without SMTP.

Internet Message Access Protocol (IMAP): This protocol defines the storage and retrieval of email. The latest version, IMAP4, is quite similar to POP3 but it has some additional features. With IMAP4, you can search through your email messages using keywords even while the messages are on the mail server. You can then decide which message to download to your device.
