What is SMTP (Simple Mail Transfer Protocol)?

Simple Mail Transfer Protocol (SMTP) is a protocol for sending email messages between servers. Most email systems that send mail over the Internet use SMTP to send messages from one server to another, and to deliver messages to local mail clients like Microsoft Outlook or Apple Mail.

SMTP is a simple, text-based protocol that is designed to transmit email messages between servers. It uses a series of commands and responses to send and receive messages. When you send an email message, your email client sends the message to the mail server using the SMTP protocol. The mail server then sends the message to the recipient's mail server using the SMTP protocol. The recipient's mail server then delivers the message to the recipient's email client.

SMTP is a widely-used protocol, and it is supported by most email servers and clients. However, it does have some limitations, such as the fact that it does not support the transmission of binary files or non-text data. For this reason, other protocols, such as MIME (Multipurpose Internet Mail Extensions), are often used in conjunction with SMTP to transmit more complex messages.
