SpamAssassin設定にカスタムルールセットがあります。サービス（systemctl start spamassassin）を起動すると、次のルールがテストスパムに対して正しく評価されます。
[antek@mailgate ~]$ cat /tmp/spam.txt | spamc -R -l

結果は、「spamc」を使用した後続のテストでも同じです。
spamassassinサービスを再起動すると、私のカスタムルールが評価されるため、「この電子メールはスパムです」という結論が再び出てきますが、もう一度試してみると同じです。その後のすべての呼び出しは私のカスタムルールを無視し、電子メールはもはやスパムではありません。
デバッグモードで実行すると、spamd私のカスタムプロファイルが表示されますが、「すでにロードされている」ため、ロードされません。これはspamasassinのバグですか？

ここで何が間違っている可能性がありますか？
現在のソースコードを変更すると機能します。
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 #}
しかし、私の考えでは、この問題はより良い方法で解決されるべきです。 :)
