smtp.zoho.com and codeigniter

Hi Sir,

I'm having issues while sending emails using Zoho smtp from my server.

I'm getting issue:

Severity: Warning
Message: fsockopen(): Peer certificate CN=`serv.makeallwebsites.com' did not match expected CN=`smtp.zoho.com'
Filename: libraries/Email.php

I already checked and confirm my SSL certificate validity and it has no issues.

You can too check it from here

and my code to send email:

    $config = Array(
          'protocol' => 'smtp',
          'smtp_host' => 'ssl://smtp.zoho.com',
          'smtp_port' => 465,
          'smtp_user' => SENDER_EMAIL, // change it to yours
          'smtp_pass' => SENDER_PASS, // change it to yours
          'mailtype' => 'html',
          'charset' => 'utf-8', //iso-8859-1
          'wordwrap' => TRUE,
          'newline' => "\r\n"
    );

    $this->load->library('email', $config);
    $this->email->set_newline("\r\n");
    $this->email->from(SENDER_EMAIL);
    $this->email->to(SENDER_EMAIL);
    $this->email->subject("Job-Request");
    $this->email->message($content);
    //$this->email->attach($path.'/'.$file_name);

    if($this->email->send())
    {
        echo 'Email send.';
    }
    else
    {
        show_error($this->email->print_debugger());
    }

Please help me to solve this issue
