Can't send mail over php - php

Question

I have a form where an user enters into a message, and the message gets sent to the recipient on the other end. I have tried this script multiple times, scoured tutorials, yet I can't seem to find what's wrong. Any ideas?
HTML Form:
<form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" >
<?php
if(isset($sent))
echo 'Your message has been sent. '; ?>
<label for="Name">Name</label><br />
<input type="text" class="textbox" size="35" id="Name" name="Name" <?php if(isset($name)) echo "value=\"$name\"";?> /><br />
<label for="Service">Service</label><br />
<input type="text" size="35" class="textbox" id="Service" name="Service" <?php if(isset($subject)) echo"value=\"$subject\"";?> /><br />
<label for="Email">Email</label><br />
<input type="text" size="35" class="textbox" id="Email" name="Email" <?php if(isset($from)) echo"value=\"$from\""; ?> /><br />
<label for="message">Message</label><br />
<textarea rows="95" cols="100" id="message" name="message"><?php if(isset($message)) echo"$message"; ?></textarea><br />
<button type="submit">Send Message</button>
</form>
PHP:
if(isset($_POST['Name']) && isset($_POST['Email']) && isset($_POST['Service']) && isset($_POST['message'])) {
$name = $_POST['Name'];
$from = $_POST['Email'];
$subject = $_POST['Service'];
$to = "emailtestertora#gmail.com";
$message = $_POST['message'];
mysql_query("INSERT INTO `Contact`(`Name`, `Email`, `Message`, `Service`) VALUES('$name', '$from', '$message', '$subject')");
$headers = "From:".$from;
if(mail($to,$subject,$message,$headers))
$msgsent = true;
}
Thanks!

Answer 1

(Apologies as this should go as a comment, but it'll be easier layed out in the textbox)
Firstly, debug with the following code:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 'on');
if (mail('emailtestertora#gmail.com', 'test', 'test')) {
echo 'Mail Sent';
} else {
echo 'Mail Failed';
}
?>
This script will give you an error message when sending the e-mail that will help you debug.
BUT, the important part of this comment, is that the e-mail script above is open to spam (as well as SQL injection). I would strongly encourage you to use a one of the functions/classes that are available that will help you cut out the security holes holes in your mail script.
If you are determined to roll-your-own then great, but please read up about e-mail spam header injection before letting this script on a server. Spammers can send thousands of e-mails very quickly when they find an open script like this, they regularly test automatically so you must clamp down.
(And read up about PHP Database object - PDO - at the same time to save the MySQL injection.)

Answer 2

Your service provider may block your mail.
If you are in dedicated server you may need to configure a mail server

Use this method
this is a php email script which dose not need any smpt connection
<?php
$to = "someone#example.com";
$subject = "Test mail";
$message = "Hello! This is a simple email message.";
$from = "someonelse#example.com";
$headers = "From:" . $from;
mail($to,$subject,$message,$headers);
echo "Mail Sent.";
?>
