命令终止，状态为 255 5.3.0-电子邮件到短信

Question

我在尝试通过通讯组列表发送电子邮件时收到以下错误，例如电子邮件到 SMS：

This is the mail system at host email-to-sms-0x.xxx.com.

I'm sorry to have to inform you that your message could not
be delivered to one or more recipients. It's attached below.

For further assistance, please send mail to

The mail system

(expanded from
<7afc3e8f8de82@dist.test.com>): Command died with status
255: "/etc/mail/XXX.php". Command output: _

Final-Recipient: rfc822; dist-TEST-com@email-to-sms-02.test.com
Original-Recipient: rfc811;7afc3e8f8de82@dist.test.com
Action: failed
Status: 5.3.0
Diagnostic-Code: x-unix; _

服务器使用 postfix，我不确定如何继续。这是否是由于 php cronjob 未执行或权限不正确？

如有任何帮助，我们将不胜感激。这是 Centos OS。我更改了一些输出以保护数据。

亲切的问候阿里 G

您需要检查电子邮件到短信的 mail.log-0x.xxx.com -- 因为 Postfix 不会泄露它在退回中获得的所有信息。

可能是权限问题，是的:)
