Massive mail() error...

[boburmum1]

<?php

$submit = $_POST['submit'];

$id = $_GET['id'];

$firstname = strip_tags($_POST['firstname']);
$lastname = strip_tags($_POST['lastname']);
$email = addslashes(strip_tags($_POST['email']));
$username = addslashes(strip_tags($_POST['username']));
$password = addslashes(strip_tags($_POST['password']));
$verifypassword = strip_tags($_POST['verifypassword']);
$date = date("Y-m-d");

if($submit){
    if($firstname&&$lastname&&$email&&$username&&$password&&$verifypassword&&$date){        

        if($password == $verifypassword){
            if(strlen($firstname)>25||strlen($lastname)>25||strlen($username)>25){
                echo "<b>Maximum limit</b> for the First, Last and username's are 25 characters";
            }else{
                if(strlen($password)>25||strlen($password)<6){
                    echo "Password must be <b>between</b> 6 and 25 characters!";
                }else{
                    $password = md5($password);
                    $verifypassword = md5($verifypassword);

                $random = rand(23456789,98765432);

                $sql = "INSERT INTO users VALUES('','$firstname','$lastname','$email','$random','0','$username','$password','$date')";
                $res = mysql_query($sql) or die(mysql_error());

                $lastid = mysql_insert_id();


                $to = $_POST['email'];
                $subject = "Activate your account!";
                $body = "

                Hello $firstname $lastname,\n\n

                You need to activate your account with the link below...

                http://localhost/projects/p_web/index.php?p=activate&id=$lastid&code=$random\n\n

                Thanks!

                ";                                       

                mail($to, $subject, $body);

                echo "Success! Check your email to activate your account!";

                }
            }
        }
    }else{
        echo "Passwords <b>Do Not Match</b>!";
    }
 }else{
    echo "Please fill in <b>all</b> fields!";
 }


?>

<form action="index.php?p=reg" method="POST"> 
    <table>
        <h1>Register</h1>
        <tr><td>First Name: </td><td><input type="text" name="firstname" value="<?php echo $firstname; ?>" /></td></tr>
        <tr><td>Last Name: </td><td><input type="text" name="lastname" value="<?php echo $lastname; ?>" /></td></tr>
        <tr><td>Email: </td><td><input type="text" name="email" value="<?php echo $email; ?>" /></td></tr>
        <tr><td>Username: </td><td><input type="text" name="username" value="<?php echo $username; ?>" /></td></tr>
        <tr><td>Password: </td><td><input type="password" name="password" /></td></tr>
        <tr><td>Verify Password: </td><td><input type="password" name="verifypassword" /></td></tr>
        <tr><td><input type="submit" name="submit" value="Register" /></tr></td>
    </table>
</form>

But this is the bit I want to look at in particular

$to = $_POST['email'];
                    $subject = "Activate your account!";
                    $body = "

                Hello $firstname $lastname,\n\n

                You need to activate your account with the link below...

                http://localhost/projects/p_web/index.php?p=activate&id=$lastid&code=$random\n\n

                Thanks!

                ";   

                $headers = "From: [e-mail]";

                ini_set("SMTP", "smtp.googlemail.com");                                    

                mail($to, $subject, $body, $headers);

                echo "Success! Check your email to activate your account!";

And I get this error

Warning: mail() [function.mail]: SMTP server response: 530 5.7.0 Must issue a STARTTLS command first. l23sm27686503wbb.8 in C:\xampp\htdocs\projects\p_web\include\reg.php  on line 53

And my php.ini settings are

[mail function]
; For Win32 only.
SMTP = smtp.googlemail.com
smtp_port = 465

; For Win32 only.
;sendmail_from = [e-mail]

And the email never sends...

[sneakyimp]

Sounds like the mail function on your server doesn't implement the mail protocol like google expects it to. I managed to send mail using google servers by using PEAR Mail.

[bradgrafelman]

The STARTTLS implies that the Google mail server only accepts SSL connections, something that the internal mail() function can't do (among many other things). It is for this reason that I (along with many others) never really use the mail() function much. Instead, you should look into using 3rd party SMTP/e-mail classes such as the one sneakyimp suggested above (or others, such as PHPMailer, XPertMailer, etc. etc.). You'll want to make sure that the package you choose to use supports SSL connections.

[sneakyimp]

I would not recommend using PHPMailer for a google server. I recall having a lot of trouble getting them to play nice together.
