Answer 1

for sending mail from local i'm using SMTP. Please change your code with following code. It's working for me. Do not edit system file. That will create problem for you in future.
$config['protocol'] = 'smtp';
$config['smtp_host'] = 'ssl://smtp.googlemail.com';
$config['smtp_user'] = '********'; //your email id
$config['smtp_pass'] = '********'; //email id password
$config['smtp_port'] = 465;
$config['smtp_timeout'] = 5;
$config['wordwrap'] = TRUE;
$config['wrapchars'] = 76;
$config['mailtype'] = 'html';
$config['charset'] = 'utf-8';
$config['validate'] = FALSE;
$config['priority'] = 3;
$config['crlf'] = "\r\n";
$config['newline'] = "\r\n";
$config['bcc_batch_mode'] = FALSE;
$config['bcc_batch_size'] = 200;
