problem with codeigniter html mail

[eluser]LoRdCoStE[/eluser]
mm strange, because if I use the same code but instead of:

Code:

$mails = array();
        
        foreach($this->mail->getMail() as $m) {
              if($this->_isValidMail($m['mail']))
             $mails[] = trim($m['mail']);
        }

use:

Code:

$mails = array();
$mails[0] = '[email protected]';

I recive the email and is readable, the client is the same because my address is also stored in the database so is returned by $this->mail->getMail(), but in that case the mail is not readable :/
