PHP Depreciated notice

Hi there,
Awesome plugin, thank you!

I’m getting a PHP Depreciated notice in my debug log, here are the details:

PHP Deprecated: __autoload() is deprecated, use spl_autoload_register() instead in /wp-content/plugins/gmail-smtp/PHPMailer/PHPMailerAutoload.php on line 45

Looking at the code in question, it seems to be in there for compatibility with PHP older than 5.1.2.
As your plugin states a minimum requirement of PHP 5.6 does this need to be in there?

If it doesn’t, am I safe to remove this:

`else {
/**
* Fall back to traditional autoload for old PHP versions
* @param string $classname The name of the class to load
*/
function __autoload($classname)
{
PHPMailerAutoload($classname);
}
}`

Not a big deal at all of course, I’m just trying to clean up my error log 🙂

Thanks for your help!

Kind regards,
JP
