PHP Mailing Blues

[chain2005]

I'm building an autoresponder service similiar to 1ShoppingCart.com and frankly I'm having the PHP Mailing Blues... It should be so much easier! I can get everything to mail out fine the problem is a lot of spam blockers are blocking my emails. I started off using the mail() but new it's limitations soon moved to a pre-coded SMTP mailer (see code below)... Now everytime an email is sent out to like a Hotmail account it always goes directly into the Junk Mail container. Hotmail is saying all these emails do not have a SENDER ID. I'm not sure what that is or how to set one, which is pretty much why I've come here! If anyone knows how I could fix this, I would owe my deepest gratitude to! This problem has been costing me a lot of time! Just a reminder everything works properly when sent to a local email but outside emails are not working...

 

function authSendEmail($from, $namefrom, $to, $nameto, $subject, $message)
{
    //SMTP + SERVER DETAILS
    /* * * * CONFIGURATION START * * * */
    $smtpServer = "localhost";
    $port = "25";
    $timeout = "30";
    $username = "";
    $password = "";
    $localhost = "localhost";
    $newLine = "\r\n";
    /* * * * CONFIGURATION END * * * * */
    
    //Connect to the host on the specified port
    $smtpConnect = fsockopen($smtpServer, $port, $errno, $errstr, $timeout);
    $smtpResponse = fgets($smtpConnect, 515);
    if(empty($smtpConnect)) 
    {
        $output = "Failed to connect: $smtpResponse";
        return $output;
    }
    else
    {
        $logArray['connection'] = "Connected: $smtpResponse";
    }

    //Request Auth Login
    fputs($smtpConnect,"AUTH LOGIN" . $newLine);
    $smtpResponse = fgets($smtpConnect, 515);
    $logArray['authrequest'] = "$smtpResponse";
    
    //Send username
    fputs($smtpConnect, base64_encode($username) . $newLine);
    $smtpResponse = fgets($smtpConnect, 515);
    $logArray['authusername'] = "$smtpResponse";
    
    //Send password
    fputs($smtpConnect, base64_encode($password) . $newLine);
    $smtpResponse = fgets($smtpConnect, 515);
    $logArray['authpassword'] = "$smtpResponse";

    //Say Hello to SMTP
    fputs($smtpConnect, "HELO $localhost" . $newLine);
    $smtpResponse = fgets($smtpConnect, 515);
    $logArray['heloresponse'] = "$smtpResponse";
    
    //Email From
    fputs($smtpConnect, "MAIL FROM: $from" . $newLine);
    $smtpResponse = fgets($smtpConnect, 515);
    $logArray['mailfromresponse'] = "$smtpResponse";
        
    //Email To
    fputs($smtpConnect, "RCPT TO: $to" . $newLine);
    $smtpResponse = fgets($smtpConnect, 515);
    $logArray['mailtoresponse'] = "$smtpResponse";
    
    //The Email
    fputs($smtpConnect, "DATA" . $newLine);
    $smtpResponse = fgets($smtpConnect, 515);
    $logArray['data1response'] = "$smtpResponse";
    
    //Construct Headers
    $headers  = "MIME-Version: 1.0" . $newLine;
    $headers .= "Content-type: text/html; charset=iso-8859-1" . $newLine;
    $headers .= "To: $nameto <$to>" . $newLine;
    $headers .= "From: $namefrom <$from>" . $newLine;
    
    fputs($smtpConnect, "To: $to\nFrom: $from\nSubject: $subject\n$headers\n\n$message\n.\n");
    $smtpResponse = fgets($smtpConnect, 515);
    $logArray['data2response'] = "$smtpResponse";
    
    // Say Bye to SMTP
    fputs($smtpConnect,"QUIT" . $newLine); 
    $smtpResponse = fgets($smtpConnect, 515);
    $logArray['quitresponse'] = "$smtpResponse";    
}

I am not too darn familiar with mail() but I think you have to add this in the headers

 

$headers .= "X-Mailer: PHP/" . phpversion(); 

 

I am pretty sure that this is the SENDER ID it is looking for.

Hey,

 

I've just added that and it seems to work a little better now 1 out of the 2 that previously blocked it doesn't block it! Any other ideas on how to fix it?

 

Thanks!
