CodeIgniter unable to send email using PHP mail()

I'm trying to send an e-mail with Codeigniter like this:

$this->load->library('email');

$this->email->from("myemail@email.com");
$this->email->reply_to("myemail@email.com");
$this->email->to("myemail@email.com");
$this->email->subject("Test mail");
$this->email->message("Email body");
$this->email->set_alt_message("Email body txt");
$this->email->send();

and I got this on the email debugger: Unable to send email using PHP mail(). Your server might not be configured to send mail using this method.

If I do e simple PHP mail() function with the same addresses, it works but when I use CodeIgniter it gives me the error. So why would it work with simple mail() but not with CodeIgniter ? Any ideas ?

Thanks.

Nobody seemed to really find a definitive answer, so I did some digging around and found out why.

in system/libraries/Email.php, first look at line 1552:

if ( ! mail($this->_recipients, $this->_subject, $this->_finalbody, $this->_header_str, "-f ".$this->clean_email($this->_headers['From'])))

it seems to send everything all peachy like. I had the exact same symptoms too. To see if I was crazy, i inserted immediately before...

mail($this->_recipients, $this->_subject, $this->_finalbody)

so I basically removed all the headers and let PHP put in the defaults. Bingo! Without CI's headers, it works. With the CI headers, it doesn't. So what is it?

Digging around some more, I looked up to where html is initialized and used. Turns out it doesn't really do anything until around 1046, where it builds the message body.

from line 1048:

if ($this->send_multipart === FALSE)
{
    $hdr .= "Content-Type: text/html; charset=" . $this->charset . $this->newline;
    $hdr .= "Content-Transfer-Encoding: quoted-printable";
}
else
{
    $hdr .= "Content-Type: multipart/alternative; boundary=\"" . $this->_alt_boundary . "\"" . $this->newline . $this->newline;

    $body .= $this->_get_mime_message() . $this->newline . $this->newline;
    $body .= "--" . $this->_alt_boundary . $this->newline;

    $body .= "Content-Type: text/plain; charset=" . $this->charset . $this->newline;
    $body .= "Content-Transfer-Encoding: " . $this->_get_encoding() . $this->newline . $this->newline;
    $body .= $this->_get_alt_message() . $this->newline . $this->newline . "--" . $this->_alt_boundary . $this->newline;

    $body .= "Content-Type: text/html; charset=" . $this->charset . $this->newline;
    $body .= "Content-Transfer-Encoding: quoted-printable" . $this->newline . $this->newline;
}
