The mail function is provided in php. it can send emails directly in the program, but it requires the server to support sendmail.
Or you must set up an email sending server that does not require relay, but it is almost impossible to find an email sending relay that does not require authentication.
Therefore, emails cannot be sent successfully using the mail function.

If you are familiar with the SMTP protocol and use the socket function, you can write an efficient and stable mail sending program, but it is too difficult for general users. Fortunately, there are already many email sending modules compiled by others on the internet. we just need to download the module and call it easily, which is very convenient.

Here, we recommend a very powerful, easy-to-use and free SMTP class module-PHPMailer,
