SMTP通过codeigniter发送邮件

Question

我尝试使用 codeigniter 使用 SMTP 发送邮件。但得到以下问题。 当我在 gmail 中打开时，即使我的凭证也是正确的并且工作正常。之后，我收到以下消息。

Answer 1

您必须将$config['protocol'] = "smtp"; 更改为$config['protocol'] = "SMTP";

让我知道它是否适合你

Answer 2

试试下面的代码，它可以解决你的问题。它对我来说很完美。

$config = array();
$config['useragent']           = "CodeIgniter";
$config['mailpath']            = "/usr/bin/sendmail"; // or "/usr/sbin/sendmail"
$config['protocol']            = "smtp";
$config['smtp_host']           = "localhost";
$config['smtp_port']           = "25";
$config['mailtype'] = 'html';
$config['charset']  = 'utf-8';
$config['newline']  = "\r\n";
$config['wordwrap'] = TRUE;

$this->load->library('email');

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

$this->email->message = "Your Message";
$this->email->subject("Message Subject");
$this->email->from("user@gmail.com");
$this->email->to("admin@gmail.com");
$this->email->send();
