我有问题,我听不懂.
这是我的代码

$this->load->library('email');
$config['protocol'] = 'sendmail';
$config['mailpath'] = '/usr/sbin/sendmail';
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = TRUE;


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

$this->email->from('rudzstyle@yahoo.co.id', 'Your Name');
$this->email->to('rudzstyle@gmail.com');
$message = $data->nama_depan.'<br>'.$this->input->post('snk');
$this->email->subject($message);
$this->email->message('Testing the email class.');

$this->email->send();

echo $this->email->print_debugger();

这2个电子邮件是有效电子邮件.

调试器的结果是

Exit status code: 1 Unable to open a socket to Sendmail. Please check
settings. Unable to send email using PHP Sendmail. Your server might
not be configured to send mail using this method.

Testing the email class.

解决方法:

在Codeigniter中,试试这个

$this->load->library('email');
$config['protocol']='smtp';
$config['smtp_host']='your host';
$config['smtp_port']='465';
$config['smtp_timeout']='30';
$config['smtp_user']='your mail id';
$config['smtp_pass']='your password';
$config['charset']='utf-8';
$config['newline']="\r\n";
$config['wordwrap'] = TRUE;
$config['mailtype'] = 'html';
$this->email->initialize($config);
$this->email->from('no-reply@your-site.com', 'Site name');
$this->email->to('to-address-mail-id');
$this->email->subject('Notification Mail');
$this->email->message('Your message');
$this->email->send();

在$config [‘smtp_user’]字段中,提供您的email_id,在$config [‘smtp_pass’]字段中,提供该邮件的密码.

这将起作用.尝试一下.
希望这能解决您的问题.
