自从将 Gentoo 盒子从 postfix 2.5.5 升级到 2.6.6 后，本地邮件传递不再起作用。虚拟邮箱仍然有效。
以下是日志：

weser.XXX.YY本地机器在哪里。我尝试-v打开开关local，qmgr但没有什么帮助。
我对如何进一步调试一无所知。尝试跟踪进程debugger_command没有生成任何预期的输出文件。
问题：
- 我该如何进一步调试呢？
- 从 2.5 升级到 2.6 之前我应该注意什么吗？
更新：我设法获取了一个 strace 日志，看起来在从活动队列读取假脱机文件后立即发生了段错误。
更新 2：我设法获取了核心转储并创建了回溯：

答案1
/usr/lib/postfix/local以信号 11 退出，这是段错误。这不是后缀问题，而是本地机器的问题。按可能性排序，我会检查：
- 确保您的编译选项（例如 CFLAGS）没有错乱。缩减到类似 的选项
-O2，重新编译，然后查看是否有效。 - 同样，postfix 使用的任何库。你可以从 postfix 使用的任何库开始（因为你会看到使用损坏库的其他程序出现故障）。
- 使用以下方法测试您的 RAM：memtest86+. 让它运行一整夜。
- 测试其他硬件。
