使用Codeigniter發送電子郵件時出現主題長度問題

Question

當電子郵件主題太長時，出現以下錯誤

The following SMTP error was encountered:


451 See
http://pobox.com/~djb/docs/smtplf.html. Unable to send email using
PHP SMTP.  Your server might not be configured to send mail using
this method.

當縮短主題長度時，它可以正常工作。我的smtp config設置是

$config['protocol'] = 'smtp'; $config['smtp_host'] = 'host';
$config['smtp_port'] = '**'; $config['smtp_user'] = $email_id;
$config['smtp_pass'] = $password; $config['charset'] = 'utf-8';
$config['newline'] = "\r\n"; $config['crlf']    = "\n"; 
$config['wordwrap'] = TRUE; $config['wrapchars'] = 10;
$config['mailtype'] = "html";

提前致謝。

顯然，這是一個已知問題，是由電子郵件主題引起的，該主題超過75個字符： http : //codeigniter.com/forums/viewthread/154493/P15/#925385

更改電子郵件配置可能會有所幫助。 有兩種解決方法：

1. 使用自己的單獨配置參數創建電子郵件對象的單獨實例： $email = new CI_Email(array('newline' => "\\r\\n"));
2. 使用內聯配置字符串： $this->email->newline = "\\r\\n"; 和$this->email->crlf = "\\n";
