How does wp smtp mail plugin works

The WP SMTP Mail plugin is a popular plugin for WordPress that allows you to send emails using a third-party SMTP (Simple Mail Transfer Protocol) server instead of the default PHP mail function. Here's a breakdown of how it works:

Why use SMTP instead of PHP mail?

The PHP mail function is a built-in function in PHP that allows you to send emails. However, it has some limitations, such as:

• It may not work properly with certain email providers or servers.
• It may not be secure, as it sends emails in plain text.
• It may not provide detailed logs or error messages.

The WP SMTP Mail plugin allows you to configure your WordPress site to use a third-party SMTP server to send emails. Here's a step-by-step explanation of the process:

1. Installation and activation: You install and activate the WP SMTP Mail plugin on your WordPress site.
2. SMTP server configuration: You configure the plugin to use a third-party SMTP server by entering the server's hostname, port number, username, and password.
3. Email sending: When you try to send an email from your WordPress site (e.g., when you submit a contact form or send a notification), the plugin intercepts the email and sends it to the configured SMTP server instead of using the PHP mail function.
4. SMTP server authentication: The SMTP server authenticates the plugin using the provided username and password.
5. Email transmission: The SMTP server transmits the email to the recipient's email server.
6. Email delivery: The recipient's email server receives the email and delivers it to the recipient's inbox.
