After registering how the website is sending mail

When you register on a website, the website typically sends a confirmation email to your registered email address to verify your account and ensure that you're the one who registered. This is a common practice to prevent spam registrations and to ensure that the user has a valid email address.

Here's a high-level overview of how this process typically works:

  1. Registration: You fill out the registration form on the website, providing your email address, username, password, and other required information.
  2. Validation: The website's server-side code validates the input data to ensure that it meets the required format and is not malicious.
  3. Email generation: The website's server-side code generates an email with a unique confirmation link or code. This email is sent to the registered email address.
  4. Email delivery: The email is delivered to your email inbox by the website's email service provider (ESP) or the website's own email server.
  5. Confirmation: You receive the email and click on the confirmation link or enter the confirmation code to verify your account.
