【问题描述】：
我将 PHP 邮件脚本从 Apache 服务器移动到 Nginx 服务器的根文件夹（Ubuntu 12.0.4 LTS、MySQL、PHP5-FPM）。该表单在 Apache 服务器上运行良好，但是，在 nginx 服务器上，当我尝试发送邮件时，我收到一条错误消息。
phpinfo() 返回有关邮件设置的以下详细信息：
php-fpm - active
mail.add_x_header - On
mail.force_extra_parameters - no value
mail.log - no value
sendmail_from - no value
sendmail_path - /usr/sbin/sendmail -t -i
php.ini 声明如下：
[mail function]
; For Win32 only.
; http://php.net/smtp
SMTP = localhost
; http://php.net/smtp-port
smtp_port = 25
; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = me@example.com
; For Unix only. You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
;sendmail_path =
; Force the addition of the specified parameters to be passed as extra parameters
; to the sendmail binary. These parameters will always replace the value of
; the 5th parameter to mail(), even in safe mode.
;mail.force_extra_parameters =
; Add X-PHP-Originating-Script: that will include uid of the script followed by the filename
mail.add_x_header = On
; The path to a log file that will log all mail() calls. Log entries include
; the full path of the script, line number, To address and headers.
;mail.log =
/var/log/mail.log 声明如下：

这是否表明我的服务器上未正确设置 PHP Mail()？
非常感谢您的建议。

疑难解答101：阅读你得到的错误信息，看看他们指向的代码。

我只收到脚本内部消息“错误”：
if(mail($address, $e_subject, $msg, $headers)) { // Email has sent successfully, echo a success page. echo "<fieldset>"; echo "<div id='success_page'>"; echo "<h1>Email Sent Successfully.</h1>"; echo "<p>Thank you <strong>$name</strong>, your message has been submitted to us.</p>"; echo "</div>"; echo "</fieldset>"; } else { echo 'ERROR!'; }
