Swiftmail 无法使用 sendmail/postfix

当我尝试运行一些 Kohana swiftmailer 时，我在邮件日志中收到以下错误：

Jul 23 17:18:37 ads postfix/sendmail[5818]: fatal: execv /usr/libexec/postfix/smtpd: Permission denied

输出ls -l /usr/libexec/postfix

我曾尝试运行rpm -qa | xargs rpm --setugids

但这似乎并不能解决问题。

这只是一种预感，但我怀疑你可能正在使用 PHP 的safe_mode函数，如下所示http://php.net/manual/en/ini.sect.safe-mode.php。可执行文件可能位于 之外safe_mode_exec_dir，因此 PHP 拒绝执行它。

您的 /usr/libexec/postfix 目录的权限没有任何问题。在我的 CentOS 6.5 机器上，权限完全相同：

您可以检查 /etc/php.ini 以了解当前的安全模式设置：

; Safe Mode
; http://www.php.net/manual/en/ini.sect.safe-mode.php#ini.safe-mode
safe_mode = Off
