发送附件时电子邮件失败

Question

I just moved my website from one hosting company to another. But in the process, my email function doesn't work if I send with an attachment.

This is from the debugger:

Unable to send email using PHP mail(). Your server might not be configured to send mail using this method.
User-Agent: CodeIgniter

Testing the email class.

Testing the email class.

--B_ATC_51a901aa74aa0
Content-type: image/png; name="screenshot.png"
Content-Disposition: attachment;
Content-Transfer-Encoding: base64

This is my code

$config['set_newline'] = "\r\n";
$config['mailtype'] = 'html';
$config['charset'] = 'iso-8859-1';
$config['wordwrap'] = TRUE;

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

$this->email->from('me@mysite.org', 'Me');
$this->email->to('someone@someone.com'); 

$this->email->subject('Email Test');
$this->email->message('Testing the email class.'); 
$this->email->attach('screenshot.png'); //I put it on root directory of CI 

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

But if I send email with attachments using a library outside CI, it's working. Actually, my solution right now is to make a helper for sending mail not using the CI library. But if there's any way I could still using CI library, it would be great.

I had the same problem and was able to solve it by changing the email.php file in system/libraries folder of codeigniter

var $protocol = "smtp"; // mail/sendmail/smtp
var $smtp_host = "localhost";  // SMTP Server.

The problem seemed to be the mail protocol in the first line above.

You may also have to add username and the password in teh next two lines if you have those setup

var $smtp_user = "my_username";  // SMTP Username
var $smtp_pass = "my_password";  // SMTP Password
