Answer 1

CPanel blocks access to external SMTP servers by default.
Disable this restriction in whm > security center > SMTP Restrictions disable
This works
<?php
require_once('./class.phpmailer.php');
$mail = new PHPMailer(); // create a new object
$mail->IsSMTP(); // enable SMTP
$mail->SMTPDebug = 1; // debugging: 1 = errors and messages, 2 = messages only
$mail->SMTPAuth = true; // authentication enabled
$mail->SMTPSecure = 'ssl'; // secure transfer enabled REQUIRED for Gmail
$mail->Host = "smtp.mail.yahoo.com";
$mail->Port = 465; // or 587
$mail->IsHTML(true);
$mail->Username = "xxxxxx#ymail.com";
$mail->Password = "xxxxxx";
$mail->SetFrom("xxxxx#ymail.com");
$mail->Subject = "Test";
$mail->Body = "hello";
$mail->AddAddress("xxxxx#ymail.com");
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message has been sent";
}?>

You might have forgotten to enable SMTP access (it's part of IMAP access in settings) to your GMail account.
Also, "tls://smtp.gmail.com" is not a valid SMTP server address. Use $mail->SMTPSecure = "tls"; if you want to use TLS.

Thanks for your suggestions, It's really appreciated :-)
I got the solution is as follows.
1>give Absolute path for PHPMailerAutoload.php
2>host name as "localhost"
3>create dummy emailId on server
<?php
require'/home/username/public_html/phpmailertesting/PHPMailer/PHPMailerAutoload.php';
$mail = new PHPMailer;
$mail->SMTPDebug =3; // Enable verbose debug output
$mail->isSMTP(); // Set mailer to use SMTP
$mail->Host = 'localhost'; // Specify main and backup SMTP servers
$mail->SMTPAuth = true; // Enable SMTP authentication
$mail->Username = 'info#hostname.com'; // SMTP username
$mail->Password = '*****'; // SMTP password
$mail->SMTPSecure = 'tls'; // Enable TLS encryption, `ssl` also accepted
$mail->Port = 587; // TCP port to connect to
$mail->setFrom('info#hostname.com', 'Mailer');
$mail->addAddress('*******#gmail.com'); // Name is optional
//$mail->addReplyTo('info#hostname.com', 'Information');
//$mail->addCC('*******#gmail.com');
//$mail->addBCC('bcc#example.com');
//$mail->addAttachment('/var/tmp/file.tar.gz'); // Add attachments
//$mail->addAttachment('/tmp/image.jpg', 'new.jpg'); // Optional name
$mail->isHTML(true); // Set email format to HTML
$mail->Subject = 'Here is the subject';
$mail->Body = 'This is the HTML message body <b>in bold!</b>';
$mail->AltBody = 'This is the body in plain text for non-HTML mail clients';
if(!$mail->send()) {
echo 'Message could not be sent.';
echo 'Mailer Error: ' . $mail->ErrorInfo;
exit();
} else {
echo 'Message has been sent';
}
?>

You need to buy Cpanel/WHM from the ISP company to enable access to external SMTP emails like Gmail. first, disable: WHM > security center > SMTP Restrictions is Disable.
and make sure CSF Firewall is "SMTP_BLOCK" setting is enabled.
if you using Gmail in your security setting enable less security which you can smtp auth.
PHPMailer recommended using SSL for all firewalls and security issues.
