Simple Mail Transfer Protocol: Option Available To Send Your Emails

Swati Jangir16 May, 2023Technology

Simple Mail Transfer Protocol (SMTP) is a widely used protocol for sending emails over the internet. It is a reliable and efficient method for transferring electronic mail from one computer to another. SMTP provides the framework for email communication by defining how email messages should be formatted, transmitted, and delivered. Here are some key points to understand about SMTP: Message Transmission: SMTP is responsible for the transmission of email messages from the sender's mail server to the recipient's mail server. It establishes a connection between the two servers and transfers the email data. Port Number: SMTP uses port number 25 for communication. However, port 587 is commonly used for secure SMTP (SMTPS) connections over TLS/SSL. This helps in securing the email transmission by encrypting the communication channel.
