sendmail email not working

[eluser]Zocee[/eluser]
I'm getting problem in sending email. CI script says email sent but i'm not getting email in my inbox as well as spam.

In this server general PHP mail() function is working. I used to use phpmailer class previously but it is also now working good. Now i've shifted to Codeigniter and its not sending email.

I've changed the server to another one but in this new server also same problem. General php mail function and class phpmailer is working but not CI mail.

Please help me.


==================
Controller function is like follows:

function emailchk(){
$this->load->library('email');
$config['protocol'] = 'sendmail';
$config['mailpath'] = '/usr/sbin/sendmail';
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = TRUE;
$config['useragent'] = "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.8) Gecko/20100722 Firefox/3.6.8 (.NET CLR 3.5.30729)";

$this->email->initialize($config);
$this->email->from('[email protected]', 'my friend name');
$this->email->to('[email protected]');
$this->email->subject('Email Test Subject');
$this->email->message('Testing the email body');
$this->email->send();
echo $this->email->print_debugger();
}


==================
Output of debugger is:
