电子邮件从未收到过如果邮件正文中有一个URL - Codeigniter

Question

我尝试发送带有codeigniter库的电子邮件。简单的普通电子邮件工作完美，但只要我输入任何URL，如www.abc.com，codeigniter就会发送电子邮件，但我从未收到过。我将邮件类型更改为HTML而没有运气。

请任何想法。

$this->load->library('email');
$config['mailtype'] = "html";
$config['charset'] = "utf-8";
$config['priority'] = "1";
$this->email->initialize($config);
$this->email->from("myemail@gmail.com", 'TS');
$this->email->to("myemail@gmail.com");
$this->email->subject('Test Email');

$txt_site_name = "www.google.com";

$this->email->message("This is test email with link --> ".$txt_site_name);

if($this->email->send())
{
    echo "The email has been sent";
}else{
    echo "Could not send the email";
    show_error($this->email->print_debugger());
}
