Answer 1

Take a look at PHP Mailer:
https://github.com/PHPMailer/PHPMailer
Example from that page:
<?php
require 'PHPMailerAutoload.php';
$mail = new PHPMailer;
//$mail->SMTPDebug = 3; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'smtp1.example.com;smtp2.example.com'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'user#example.com'; // SMTP username
$mail->Password = 'secret'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587; // TCP port to connect to
$mail->From = 'from#example.com';
$mail->FromName = 'Mailer';
$mail->addAddress('joe#example.net', 'Joe User'); // Add a recipient
$mail->addAddress('ellen#example.com'); // Name is optional
$mail->addReplyTo('info#example.com', 'Information');
$mail->addCC('cc#example.com');
$mail->addBCC('bcc#example.com');
$mail->WordWrap = 50; // Set word wrap to 50 characters
$mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
echo 'Message has been sent';
}

Answer 2

$mail = new PHPMailer();
$mail->IsSMTP();
$mail->CharSet = 'UTF-8';
$mail->Host = "mail.example.com"; // SMTP server example
$mail->SMTPDebug = 0; // enables SMTP debug information (for testing)
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->Port = 25; // set the SMTP port for the GMAIL server
$mail->Username = "username"; // SMTP account username example
$mail->Password = "password"; // SMTP account password example

Please try this
Create library file for the SMTP Settings 'library.php':
<?php
error_reporting(0);
define("SMTP_HOST", "SMTP_HOST_NAME"); //Hostname of the mail server
define("SMTP_PORT", "SMTP_PORT"); //Port of the SMTP like to be 25, 80, 465 or 587
define("SMTP_UNAME", "VALID_EMAIL_ACCOUNT"); //Username for SMTP authentication any valid email created in your domain
define("SMTP_PWORD", "VALID_EMAIL_ACCOUNTS_PASSWORD"); //Password for SMTP authentication
?>
Make the form post and do the below actions:
<?php
include 'library.php';
include "classes/class.phpmailer.php"; // include the class file name
if(isset($_POST["send"])){
$email = $_POST["email"];
$mail = new PHPMailer; // call the class
$mail->IsSMTP();
$mail->Host = SMTP_HOST; //Hostname of the mail server
$mail->Port = SMTP_PORT; //Port of the SMTP like to be 25, 80, 465 or 587
$mail->SMTPAuth = true; //Whether to use SMTP authentication
$mail->Username = SMTP_UNAME; //Username for SMTP authentication any valid email created in your domain
$mail->Password = SMTP_PWORD; //Password for SMTP authentication
$mail->AddReplyTo("reply#yourdomain.com", "Reply name"); //reply-to address
$mail->SetFrom("from#yourdomain.com", "Asif18 SMTP Mailer"); //From address of the mail
// put your while loop here like below,
$mail->Subject = "Your SMTP Mail"; //Subject od your mail
$mail->AddAddress($email, "Asif18"); //To address who will receive this email
$mail->MsgHTML("<b>Hi, your first SMTP mail has been received. Great Job!.. <br/><br/>by <a href='http://asif18.com'>Asif18</a></b>"); //Put your body of the message you can place html code here
$mail->AddAttachment("images/asif18-logo.png"); //Attach a file here if any or comment this line,
$send = $mail->Send(); //Send the mails
if($send){
echo '<center><h3 style="color:#009933;">Mail sent successfully</h3></center>';
}
else{
echo '<center><h3 style="color:#FF3300;">Mail error: </h3></center>'.$mail->ErrorInfo;
}
}
?>
Please edit your email and password correctly.

Answer 4

you can employ the use of the phpmailer library since the mail() function has limitations in its use. so I prefer using PHPmailer it is easier to work with than the mail() function.
I also used the mail() function it requires a lot of settings here and there and cannot be used to send remote mail messages.
so in short, the mail() function is only suitable when working with the local server but not suitable when you want to work with a remote server.
