我在Windows服务器上使用codeigniter和phpmailer为其联系表单创建了一个网站，此设置运行良好。几天前我决定在Linux服务器上创建另一个网站，我使用了几乎相同的代码，但我的联系表格似乎没有用。
我的控制器中的代码
$email_config=array(
"protocol"=>"smtp",
"mailpath"=>"/usr/sbin/sendmail",
"smtp_host"=>"mail.dnweb-solutions.com",
"smtp_user"=>"contact@mail.dnweb-solutions.com",
"smtp_pass"=>"****",
"smtp_port"=>25,
);
$this->load->library("email");
$this->email->initialize($email_config);
$this->email->to("sobsdinike@gmail.com");
$this->email->from("contact@mail.dnweb-solutions.com",$_POST["fullname"]);
$this->email->reply_to($_POST["email"],$_POST["fullname"]);
$this->email->subject($_POST["subject"]);
$this->email->message($_POST["message"]);
$this->email->send();
我的config / email.php中的代码
