General email sending system process

To better understand the implementation of the mail sending function, you must first understand the general process of the mail sending system. First, emails are sent and accepted from one site (mail sending server) to the destination site (Mail receiving server), and then the destination site processes the received emails, and send it to the receiver. Each email server acts as the sender and receiver, and the address, port number, and configuration of each server are also different.

In fact, there are two steps to send an email:

First, write an email.

• Write the sender and receiver
• Write a topic
• Write the text (including attachments and images)
• Sort emails together

Second, send an email

• Connect to the email sending server
• Logon email
• Send email
• Exit email
