如何调试＆＃34;无法发送AUTH LOGIN命令＆＃34;在CodeIgniter中发送给GMail时？

Question

我使用打印调试器检查它是否已发送，以及我得到的回报：

bool(false) 220 smtp.gmail.com ESMTP t8sm1776565pgr.21 - gsmtp

当我将smtp_port更改为465时，我得到了响应，如

出于安全考虑，我已将此电子邮件ID隐藏在此问题中。

我找到了很多代码示例，他们想要更改本地php.ini和sendmail.ini文件以发送电子邮件，但我认为这不是使用smtp发送邮件的要求。

我也使用PHPmailer lib，它适用于smtp邮件，但为什么CodeIgniter电子邮件lib for SMTP不起作用？此CodeIgniter SMTP设置支持哪个PHP版本？

试试这个： -

                             $ci = get_instance();
                             $ci->load->library('email');
                             $config['protocol']  = "smtp";
                             $config['smtp_host'] = "mail.google.com";
                             $config['smtp_port'] = "26";
                             $config['smtp_user'] = "********@gmail.com";
                             $config['smtp_pass'] = "************";
                             $config['charset']   = "utf-8";
                             $config['mailtype']  = "html";
                             $config['newline']   = "\r\n";

                             $ci->email->initialize($config);

                             $ci->email->from('*********@gmail.com');

                             $email_body = "Sending Email from server.";

                            $this->email->to($userEmail']);
                            $this->email->subject('Email Subject');
                            $this->email->message($email_body);
                            $email = $this->email->send();
