电子邮件不发送代码点火器

Question

I'm having a big problem with code igniter emails. When i'm working localhost the email is normaly send by smtp protocol, but when i up to the server the mail sending is not working.

My mail configurations :

$config['protocol'] = 'mail';
        $config['smtp_host'] = 'mail.duplov.com.br';
        $config['smtp_port'] = '587';
        $config['smtp_timeout'] = '30';
        $config['smtp_user']= '**********';
        $config['smtp_pass'] = '***********';
        $config['charset'] = 'utf-8';
        $config['newline'] = '
';
        $config['mailtype'] = 'html';

Detail tha stmp_pass and stmtp_user i just hide. My send email code :

public function validacao(){
        $this->load->library('form_validation');
        $this->form_validation->set_rules('nome','Nome','required|min_length[5]');
        $this->form_validation->set_rules('email','Email','required|valid_email');
        $this->form_validation->set_rules('telefone','Telefone','required|min_length[13]',array('min_length' => 'Você precisa colocar um telefone válido incluindo o DDD'));
        $this->form_validation->set_rules('mensagem','Mensagem','required|min_length[20]');

        if($this->form_validation->run() == FALSE){
            $erros = array('mensagens' => validation_errors());
            $jsonStr = json_encode($erros);
            echo $jsonStr;
        }
        else{
            if($mensagem = $this->enviar_mensagem($this->input->post('nome'),$this->input->post('email'),$this->input->post('telefone'),$this->input->post('mensagem'))){
                $sucesso['mensagens']   = 'sucesso';
                $jsonStr = json_encode($sucesso);
                echo $jsonStr;
            }else{
                $sucesso['mensagens']   = $this->email->print_debugger();
                $jsonStr = json_encode($sucesso);
                echo $jsonStr;
            }
        }
    }

    public function enviar_mensagem($nome,$email,$telefone,$mensagem){
        $this->load->model('funcoes');
        $this->funcoes ->contato($nome,$email,$telefone,$mensagem);
        $emails = $this->funcoes->get_infos();
        foreach ($emails as $em){
            $this->load->library('email');
            $dados['nome'] = $nome;
            $dados['email'] = $email;
            $dados['telefone'] = $telefone;
            $dados['mensagem'] = $mensagem;
            $mensagem = $this->load->view('email/template',$dados,true);
            $this->email->from("[e-mail]","Gerenciador do website");
            $this->email->to($em->email);
            $this->email->subject('Contato site');
            $this->email->message($mensagem);
            return $this->email->send();
        }

It is not possible to send e-mail using PHP SMTP. Your server may not be configured to send mail using this method.

Answer 1

It looks like you are using $config['protocol'] = 'mail';

Are you using the right protocol? Try changing to $config['protocol'] = 'smtp'; Make sure you enter the right smtp details and the outgoing port isn't blocked on your server too. Try another smtp server or test it again locally using MailSlurper, just to confirm.
