php mail() 权限被拒绝 /var/spool/exim 和 /var/log/exim

全新安装 CentOS 7、Exim 4.84、Httpd 2.4.6、php 5.4.16

通过 exim 发送邮件有效。使用 sendmail 命令在控制台中发送邮件有效。使用 php 中的 mail() 发送邮件会出现以下错误消息（在 /var/log/maillog 中）：

检查文件权限，一切正常：

drwxr-x---. 2 exim exim     4096 Aug  2 14:32 /var/log/exim
-rw-r-----. 1 exim exim 19351762 Aug  2 15:11 /var/log/exim/main.log

答案1

这往往是一个SELinux 问题， 你需要设置正确的布尔值：

 setsebool -P httpd_can_sendmail on
