mail();
whats its DEFINITION ?
I mean seriously how can php be soo easy ? :/ you send an email just by a prebuilt function ? No messing with the tcp/ip protocols or pop3 ? How could this be ? I really need the definition to this function , gonna try to rewrite in c++

Using the default mail application on the server.

But it doesn't require you to LOGIN to an email account and just sends an email randomly

Code: [Select]

<?php
 $email = $_POST['email'];
 $content = nl2br($_POST['content']);
 $name = $_POST['name'];
 $sender = $_POST['sender'];
 $subject = $_POST['subject'];
 $headers = "From: $name "."<".$sender.">\r\n";
 //add boundary string and mime type specification
 //$headers .= 'MIME-Version: 1.0' . "\r\n";
 //$headers .= 'Content-type: text/html; charset=iso-8859-1' . "\r\n";
 //send the email
 mail($email, $subject, $content, $headers );
 ?>

Emails don't need a login account...
Read SMTP..
You can send email by  implementing the protocol.

Yeah, if you have your own smtp server, and are sending mail from that server you don't need login info. If you want to send mail using a remote smtp server, like say google's, you generally have to send a username and password.
