I would really recommend BulkEmailCleaner.com, Free stuff really dont cover everything but these guys have solution with bundle tools i am pretty sure you will like it
good luck.
This is what i recommend, just cleaned a list a few hours ago and it cleaned not only gmail but others too only skipping hotmail, yahoo and a few.A free tool was posted not too long ago, which actually cleans lists (no Hotmail or Yahoo), it doesn't only remove syntax errors. The process is done online, so you don't have to setup anything on your own. If your list contains a lot of Gmail addresses, it can be good.

You can use Send-Safe List Manager to filter your list for Gmail addresses or you can do it with Notepad++ and regex too. Then you can check the list with the above tool (10k addresses in one go, no other limits). At least you checked the Gmails.
public static function isValidEmail(string $email) : bool
{
if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
return false;
}
//Get host name from email and check if it is valid
$email_host = array_slice(explode("@", $email), -1)[0];
// Check if valid IP (v4 or v6). If it is we can't do a DNS lookup
if (!filter_var($email_host,FILTER_VALIDATE_IP, [
'flags' => FILTER_FLAG_NO_PRIV_RANGE | FILTER_FLAG_NO_RES_RANGE,
])) {
//Add a dot to the end of the host name to make a fully qualified domain name
// and get last array element because an escaped @ is allowed in the local part (RFC 5322)
// Then convert to ascii (http://us.php.net/manual/en/function.idn-to-ascii.php)
$email_host = idn_to_ascii($email_host.'.');
//Check for MX pointers in DNS (if there are no MX pointers the domain cannot receive emails)
if (!checkdnsrr($email_host, "MX")) {
return false;
}
}
return true;
}There are some online services you can use but they charge you. (To me, it might be worth paying some money to have it cleaned up automatically by a program).
/* * Check for valid MX record for given email domain */ if(!function_exists('check_email_domain')){ function check_email_domain($email) { //Get host name from email and check if it is valid $email_host = explode("@", $email); //Add a dot to the end of the host name to make a fully qualified domain name and get last array element because an escaped @ is allowed in the local part (RFC 5322) $host = end($email_host) . "."; //Convert to ascii (http://us.php.net/manual/en/function.idn-to-ascii.php) return checkdnsrr(idn_to_ascii($host), "MX"); //(bool) } }
