Postfix中Received头部字符串替换配置后无法接收邮件问题求助

我现在在用Postfix，想要把Received头部里的字符串14.03.0513.000替换成15.20.7091.31，比如下面这个头部：

Received: from srv1.somedomain.com ([11.12.13.14]) by srv2 ([12.13.14.15]) with mapi id 14.03.0513.000; Fri, 15 Dec 2023 14:28:13 -0500

但我一直没搞对语法，我在/etc/postfix/header_checks里写了这样的规则：

/^Received:(.*)14\.03\.0513\.000(.*)/ REPLACE Received:${1}15.20.7091.31${2}

结果一启用这个配置，Postfix就没法接收入站邮件了，会报错451 4.3.0 Error: queue file write error。

不过我用这个命令测试的时候是正常的：

postmap -q "Received: from srv1.somedomain.com ([11.12.13.14]) by srv2 ([12.13.14.15]) with mapi id 14.03.0513.000; Fri, 15 Dec 2023 14:28:13 -0500" regexp:/etc/postfix/header_checks

返回的结果是正确的替换后的头部：

REPLACE Received: from srv1.somedomain.com ([11.12.13.14]) by srv2 ([12.13.14.15]) with mapi id 15.20.7091.31; Fri, 15 Dec 2023 14:28:13 -0500

明明测试是对的，但Postfix还是拒绝邮件，有没有大佬知道我哪里漏了？
