Answer 1

Try this code on your live server
$firstName = "sunny";
$lastName = "khatri";
$email = '******#gmail.com';
$phone = '********';
$message ='Hello this is test';
$from= '*****#gmail.com';
$to = '***#gmail.com';
$subject = 'Message from Contact Demo ';
$txt= 'demo';
$headers = "From: ******#*****.com" . "\r\n" .
"CC: ********#live.in";
$body = "From: First-Name: $firstName\n Last-Name: $lastName\n
E-Mail: $email\n Phone: $phone\n Message: $message";
$errFirstName='';$errLastName='';$errEmail='';$errPhone='';$errMessage='';
// If there are no errors, send the email
if (mail ($to, $subject,$txt,$headers)) {
$result='<div class="alert alert-success">Thank You! I will be in touch</div>';
} else {
$result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
}
echo $result;

Just use default function from PHP manual:
<?php
$email_a = 'joe#example.com';
$email_b = 'bogus';
if (filter_var($email_a, FILTER_VALIDATE_EMAIL)) {
echo "This ($email_a) email address is considered valid.\n";
}
if (filter_var($email_b, FILTER_VALIDATE_EMAIL)) {
echo "This ($email_b) email address is considered valid.\n";
} else {
echo "This ($email_b) email address is considered invalid.\n";
}
?>

Answer 3

First You Have To Check Email Is Valid Using This Php Function
$email = test_input($_POST["email"]);
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
$emailErr = "Invalid email format";
}
Then If Its Not Valid Give A Error
Else
if (mail ($to, $subject,$txt,$headers)) {
$result='<div class="alert alert-success">Thank You! I will be in touch</div>';
} else {
$result='<div class="alert alert-danger">Sorry there was an error sending your message. Please try again later</div>';
}
try it..
