mail() on Windows and Exchange

[chadt]

I am trying to write a simple mail script that will email a users password to them when they request it. But this is on a windows IIS server, trying to connect to an exchange server to send the mail. I'm sure there has to be some kind of authentication. Can this be done in PHP?

My simple mail script looks like this:
if ($send == 'yes')
{
email_password($user_name);
if (email_password($user_name) == true)
{
echo " An email has been sent to your mailbox. Check your email in a few minutes to retrieve your password. <br/> \n";
}
else
{
echo " Failed to send notification. Please contact your administrator at webmaster@*. <br/>\n";
}
}
else
{
print("
<form name=\"forget_password\" method=\"post\" action=\"forget_password.php\">\n
--- Please enter your User Name ---<br/>
<input type=\"text\" name=\"user_name\" size=\"50\"><br/>\n
<input type=\"hidden\" name=\"send\" value=\"yes\"><br/>\n
\t<input type=\"submit\" name=\"subBTN\" value=\"Proceed\">\n
</form>\n
");

}

the email_password function looks like this:
function email_password ($user_name)
{
global $train_db;
global $web_root;
db_connect($train_db);
$query = "SELECT * FROM login WHERE user_name = '$user_name' ";
$results = @($query);

$pass = mysql_fetch_array($results);

$email = $pass[email];
$from = "From: webmaster@*. \r\n";
$mesg = "Your Training Database password is: $pass[password]";

if (mail($email, "Training Database Login Information", $mesg, $from))
{
return true;
}
else
{
return false;
}

}

I placed the IP address of the exchange server in php.ini under SMTP and my email address under sendmail_from. The account is a valid account on the exchange server.

I get an "unable to connect" error.

I've tried putting the server name instead of the ip address... same error.

thanks for any help in advance,

First make a form and write this code:
<?
include "forgotpass.php";
if ($submit) {
user_lost_password($email,$user_name);
}
if ($feedback) {
echo '<FONT COLOR="RED"><H2>'.$feedback.'</H2></FONT>';
}
echo '<H3>Reset Passowrd</H3>
<P>
Quickly fill in this info and a new password will be emailed.
<P>
<FORM ACTION="'. $PHP_SELF .'" METHOD="POST">
<B>User Name:</B><BR>
<INPUT TYPE="TEXT" NAME="user_name" VALUE="'.$user_name.'" SIZE="10" MAXLENGTH="15">
<P>
<B>Email Address:</B><BR>
<INPUT TYPE="TEXT" NAME="email" VALUE="" SIZE="30" MAXLENGTH="45">
<P>
<INPUT TYPE="SUBMIT" NAME="submit" VALUE="Reset My Password">
</FORM>';
?>

AND IN forgotpass.php write the following code:

<?
function user_lost_password ($email,$user_name) {
global $feedback,$hidden_hash_var;
if ($email && $user_name) {
$user_name=strtolower($user_name);
$sql="SELECT * FROM user WHERE user_name='$user_name' AND email='$email'";
$result=db_query($sql);
if (!$result || db_numrows($result) < 1) {
//no matching user found
$feedback .= ' ERROR - Incorrect User Name Or Email Address ';
return false;
} else {
//create a secure, new password
$new_pass=strtolower(substr(md5(time().$user_name.$hidden_hash_var),1,14));

		//update the database to include the new password
		$sql="UPDATE user SET password='$new_pass' WHERE user_name='$user_name'";
		$result=db_query($sql);

		//send a simple email with the new password
		mail ($email,'Password Reset','Your Password '.
			'has been reset to: '.$new_pass.'\n'.'Change it as soon as possible.','From: [e-mail]');
		$feedback .= ' Your new password has been emailed to you. ';
		return true;
	}
} else {
	$feedback .= ' ERROR - User Name and Email Address Are Required ';
	return false;
}

}
?>

While I appreciate the code to write a better email script... My problem persists. My mail function fails to connect to the mail server. My web server is IIS 4.0 on Windows NT 4.0 SP6a. My mail server is exchange 5.5.

Is there a way to get an IIS server to send mail through an exchange server? What settings do I need to change in php.ini? I already changed SMTP= to my exchange servers' name... didn't work. So I changed it to the exchange servers' IP address. Still couldn't connect.

Any ideas? Maybe I should ensure the webmaster email account is indeed on that server.

Again, any help is appreciated.
