我在 Debian bullseye armel 上安装了 spamassassin (3.4.6-1)。当我尝试使用 sudo systemctl start spamassassin 启动它时：
Job for spamassassin.service failed because a timeout was exceeded. See "systemctl status spamassassin.service" and "journalctl -xe" for details.
systemctl status spamassassin 的输出是：

我不知道该怎么办，但我觉得问题出在“正则表达式编译失败”错误。有什么想法吗？谢谢！
编辑：令人惊讶的是，似乎有一个 spamd 进程，尽管我仍然无法启动或重新启动 spamassassin.service：
ps aux | grep spam

EIDT 2：“sudo spamd -D”按预期工作。但我无法启动 spamassassin.service。
