SMTP Authentication in codeigniter email

[eluser]Thimuth[/eluser]
Hi,
I'm using email library to send emails using gmail smtp server.And I'm setting the from name as follows.

Code:

$config['protocol']  = 'smtp';
$config['smtp_host'] = 'ssl://smtp.gmail.com';
$config['smtp_port'] = '465';
$config['smtp_user'] = '[email protected]';
$config['smtp_pass'] = 'testmail';
..
..// initializing and setting other parameters
..
$this->email->from([email protected], 'Im the sender');
..

But, in the email i receive, it shows as :- "From : Im the sender<[email protected]> "
instead of " From : Im the sender<[email protected]> ".
This happens only when authenticate using Gmail SMTP . If you use yahoo or any other SMTP settings, from parameter will work as it should be.
This happens if you use PHPMailer library also.

Is there any way to change From parameter when Gmail SMTP is used to authenticate?
