我在 SpamAssassin 设置中制定了一系列自定义规则。当我启动服务 ( systemctl start spamassassin) 时，这些规则会在我的测试垃圾邮件上正确评估：
[antek@mailgate ~]$ cat /tmp/spam.txt | spamc -R -l
23.4/5.0
Spam detection software, running on the system "mailgate.anadoxin.org",
has identified this incoming email as possible spam. The original
message has been attached to this so you can view it or label
similar future email. If you have any questions, see
the administrator of that system for details.

...但是当我在第一次尝试后再次使用“spamc”评估电子邮件时，我的自定义规则不再存在，并且电子邮件不会被评估为垃圾邮件：

对于使用“spamc”的任何后续测试，该结果都是相同的。
当我重新启动 spamassassin 服务时，我再次得到“这封电子邮件是垃圾邮件”的结论，因为我的自定义规则已被评估，但同样仅适用于第一次尝试。任何后续调用都会忽略我的自定义规则，并且电子邮件不再是垃圾邮件。
当我spamd在调试模式下运行时，它会看到我的自定义配置文件，但不会加载它们，因为它们“已加载”；这是 spamassassin 中的错误吗？

这里可能有什么问题？
目前，当我更改源代码时它可以工作：
1887 sub read_cf_file {
1888 my($self, $path) = @_;
1889 my $txt = '';
1890
1891 #if ($self->{cf_files_read}->{$path}++) {
1892 #dbg("config: skipping already read file: $path");
1893 #return $txt;
1894 #}
但我的印象是这应该以更好的方式解决:)
