Let us see the workings of SMTP and why it is so important for business email.

  1. When you hit the SEND button, SMTP acts as a virtual postman, that connects machines, to drop your emails at the right location.
  2. SMTP jobs are to simply sort and send emails to deliver them at the receiver end server. 

Beyond that, it is the role of IMAP and POP to deliver it at the receiver PC.

It will automatically connect your message to your SMTP server, and provide it with details of your email. From there the SMTP server will carry the email to the determined receiver domain.
