Answer 1

在形式（的index.php）

<form action="sendmail.php" method="post"> 
    <lable>email</lable>> 
    <input type="text" name="email" maxlength="40"> 
    <br> 

    <input type="submit" value="Register"> 

</form> 

在sendmail.php

$rand= rand(10, 20)// random number generator 
$to = $_POST['email']; 
$header ='From:admin@domain.com'; 
$subject ='Verification Code'; 

$message = "Your Random number is"; 
$message .= $rand; 
$message .= "Thank you-Admin"; 

if(empty($to)) 
{ 
    echo "Email is Empty"; 
} 
else 
{ 
    if (mail($to,$subject,$message,$header)){ 

    echo 'Check Your Email FOr verfication code'; 
    } 
    else{ 
     echo 'Failed'; 
    } 
}

我認爲你正在使用不接受使用的mail（）函數發送的託管服務。也許出於安全原因，防止像病毒一樣的PHP腳本從您的帳戶發送垃圾郵件。
因此，創建admin@domain.com電子郵件帳戶，並使用PHPMailer發送電子郵件：

require __DIR__.'/phpmailer/PHPMailerAutoload.php'; 

$mail = new PHPMailer; 
$mail->isSMTP();      
$mail->Host = 'smtp.hostname.com'; 
$mail->SMTPAuth = true;    
$mail->Username = 'no-reply@domain.com';     
$mail->Password = 'secret';       
$mail->SMTPSecure = 'tls'; 
$mail->Port = 587;  
$mail->setFrom('admin@domain.com'); 
$mail->addAddress($to); 
$mail->isHTML(true); 
$mail->Subject = $subject; 
$mail->Body = $body; 

if(!$mail->send()) { 
    echo 'Message could not be sent.'; 
    echo 'Mailer Error: ' . $mail->ErrorInfo; 
} else { 
    echo 'Message has been sent'; 
}

你忘了在末尾添加分號第一行

$rand= mt_rand(100000, 999999) 

應該是

$rand= mt_rand(100000, 999999);
