我需要为电子邮件传输禁用反弹。有时emailtransport.php会出错，但它确实完成了我想要的工作。
如何关闭任何到电子邮件传输的反弹消息，使其不影响工作或其他传输，如其他2emailtransport
我不需要这个：

Mar 26 15:35:16 machin1 postfix/bounce[10936]: 6873F180998: sender non-delivery notification: 4FFE918099A
命令终止后，状态为255我需要删除消息6873F180998。并且不要发送绑定消息4FFE918099A。
我解决了我的问题，但它并不能完全回答我的问题。

DIAGNOSTICS
Command exit status codes are expected to follow the conventions
defined in <sysexits.h>. Exit status 0 means normal successful comple-
tion.
In the case of a non-zero exit status, a limited amount of command out-
put is logged, and reported in a delivery status notification. When
the output begins with a 4.X.X or 5.X.X enhanced status code, the sta-
tus code takes precedence over the non-zero exit status (Postfix ver-
sion 2.3 and later).
这意味着我需要让我的PHP脚本发出EXIT(0);。我打开了错误报告ini_set('error_reporting', -1);，发现脚本中有问题。当我修复这个脚本时，错误消失了，问题解决了。
思考如何解决问题的其他理论选择（但我不确定这是否可能）：
- 禁用特殊后缀传输使用反弹
- 始终将错误状态PHP脚本重写为0
- 在sysexits.h中编辑某些内容
