In the event that your mailing list gets to be more established and hasn't been utilized for quite a while, there is not kidding chance that a portion of the email locations aren't legitimate any longer.

Why do you have to check these email addresses?

Some individuals would say, why if I give it a second thought and there are individuals conveying their mailings to these invalid email addresses ordinarily.

There is gigantic danger that your mail servers will get on a boycott on the off chance that you do this.

How I checked 6000+ email addresses right from my Laptop

Regardless of the fact that you utilize a SMTP approval script, there is a chance the sending IP address gets to be on a boycott. So be watchful if your rundown is enormous!

Last time I have to check a rundown where I realize that 25% of the email addresses has bobbed while a client has send his email battles. I utilize my tablet to check them utilizing the SMTP association from my own ISP which I never use for email :)

Note, I utilized my tablet with a LAMP establishment to run the accompanying code.

Checking 6000+ email locations will take some time, so it's ideal to check littler bundles by running a CRON work. To begin with import your email addresses into a MySQL database. Make a basic table structure (ID, email, status) and import all email address utilizing the .csv import highlight from phpMyAdmin.

I've utilized the accompanying script to check all the email addresses in bundles of 25.

<?php

require dirname(__FILE__).'/smtp-validate-email.php';

$from = 'your@emailaddress.com';

if (!$db = new mysqli('localhost', 'username', 'password', 'databasename')) {

die('Can\'t connect to the database.');

} else {

// after I imported all email addresses into the data I select 25 records for validation

$res = $db->query("SELECT ID, email FROM emailaddresses WHERE status = 'valid' ORDER BY RAND() LIMIT 25");

while ($obj = $res->fetch_object()) {

$status = 'invalid';

$address = trim($obj->email);

// filter for a valid email format

if( filter_var( $adres, FILTER_VALIDATE_EMAIL ) ) {

$domain = array_pop(explode('@', $address));

// check for existing MX records

if (checkdnsrr($domain, 'MX')) {

// use the validator class to connect via SMTP

$validator = new SMTP_Validate_Email($address, $from);

$smtp_results = $validator->validate();

if ($smtp_results[$adres]) {

$status = 'valid';

}

}

}

// update the new status, otherwise you will check your records for years :)

$db->query(sprintf("UPDATE emailaddresses SET status = '%s' WHERE ID = %d", $status, $obj->ID));

}

$db->close();

} The required PHP class script (smtp-validate-email.php) is the one I’ve mentioned before. Execute the PHP script every ~5 minutes by using a CRON job.
