when check email address of yahoo domain it gives notice in php - php

Question

Hi i have used the php script for email validations.The code is working if i check the email address of gmail domain it gives correct result and check email is valid or invalid email. but when i check the email address of yahoo domain it gives error Notice: fwrite(): send of 6 bytes failed with errno=10053 An established connection was aborted by the software in your host machine.I want to avoid thie notice for yahoo address.
<div class="container" style="width:80%;margin:0 auto;">
<h3>Email Validation Script</h3>
<div class="form-group" >
<form method="post">
<label for="comment">Email Address</label>
<textarea class="form-control" name="em" id="" cols="30" rows="10" placeholder="please enter email addresses"></textarea >
<br>
<input type="submit" name="submit" value="Check email addresses" class="btn btn-primary">
</form>
</div>
</div>
require_once('smtp_validateEmail.class.php');
if(isset($_POST['submit'])){
$em= $_POST['em'];
$emails2=substr(strrchr($em, "#"), 1);
//echo $emails2;
// if($emails2 == 'yahoo.com'){
// echo "not valid";
// }
// else{
// echo "valid";
// }
$emails1 = implode(",", preg_split("/[\s]+/", $em));
$emails = explode(',',$emails1);
//$emails = array('dave1#hmgamerica.com', 'babita#gmail.com');
// an optional sender
$sender = 'user#yourdomain.com';
// instantiate the class
$SMTP_Validator = new SMTP_validateEmail();
// turn on debugging if you want to view the SMTP transaction
$SMTP_Validator->debug = true;
// do the validation
$results = $SMTP_Validator->validate($emails, $sender);
echo "<div class='container' style='width:77%;margin:0 auto;background:#F0F0F0;'>";
echo "<h3>List Of Emails</h3>";
// view results
foreach($results as $email=>$result) {
if ($result) {
echo "<div style='color:green';>
The email address $email is valid
</div>";
echo "<br>";
//mail($email, 'Confirm Email', 'Please reply to this email to confirm', 'From:'.$sender."\r\n"); // send email
} else {
// echo "not valid";
echo "<div style='color:red';>
The email address $email is invalid
</div>";
echo "<br>";
}
}
echo "</div>";
}
?>
The error is line fwrite($this->sock, $msg."\r\n");-
function send($msg) {
fwrite($this->sock, $msg."\r\n");
$reply = fread($this->sock, 2082);
$this->debug(">>>\n$msg\n");
$this->debug("<<<\n$reply");
return $reply;
}

Did you look up your error code (errno 10053)?
It hints that you are on Windows and the socket is aborting.
Perhaps: An established connection was aborted by the software in your host machine Windows 8.1
Did you try validating just one yahoo address with your library?
<?php
$SMTP_Validator = new SMTP_validateEmail();
$SMTP_Validator->debug = true;
$results = $SMTP_Validator->validate(array('foo#yahoo.com'));
var_dump($results);
You could be having some socket problems. The lib code suggests that upon socket creation failure the domain will be skipped. So it's as if the socket gets created but later there is a problem.
Try the following code in a separate file to see if you get any errors while connecting to a yahoo SMTP server:
<?php
if(getmxrr('yahoo.com', $mxhosts)) {
$sock = fsockopen ($mxhosts[0], 25, $errno , $errstr);
if(! $sock) {
var_dump($errno);
var_dump($errstr);
} else {
echo 'Socket created.';
}
}
You could also replace the lib's fwrite line temporarily (and test for just one yahoo address). This may indicate a time-out.
$meta = stream_get_meta_data($this->sock);
var_dump($meta);
die();
