Spamassassin的自定义角色（用于主题行过滤）不起作用

Question

我正在设置Spamassassin，以便与isbg一起使用，以过滤IMAP邮件帐户中的邮件。我的ISP已经有一个很好的垃圾邮件过滤器，它在检测到的每条邮件的主题行之前添加“ [SPAM]”。因此，我在Spamassassin中设置了一个自定义规则，以便为主题行以“ [SPAM]”开头的任何邮件添加高分。我的user_prefs文件是：

 required_score     9
 score HTML_COMMENT_8BITS   0
 score UPPERCASE_25_50      0
 score UPPERCASE_50_75      0
 score UPPERCASE_75_100 0
 score OBSCURED_EMAIL          0

 score SUBJ_ILLEGAL_CHARS      0

header SPAM_FILTRADO    Subject =~ /^\s*\[SPAM\]/
score  SPAM_FILTRADO    20

但是，当我向它发送垃圾邮件以对其进行测试时，它似乎并未触发我的规则。我给它提供了带有此主题行的电子邮件，例如：

Subject: [SPAM] See Drone X Pro in action

我以这种方式分析：

[paulo@myserver mails]$ spamc -R < spam7.txt 
9.3/9.0
Spam detection software, running on the system "myserver", has
identified this incoming email as possible spam.  The original message
has been attached to this so you can view it (if it isn't spam) or label
similar future email.  If you have any questions, see
@@CONTACT_ADDRESS@@ for details.

 1.3 RDNS_NONE              Delivered to internal network by a host with no rDNS

我的规则没有任何内容。

我知道我的user_prefs正在加载，因为在我上面粘贴的部分之后，我在白名单中设置了一些电子邮件地址，并且在分析来自这些地址的电子邮件时，Spamassassin可以正确检测到它们。

我的规则怎么了？

默认情况下，对user_prefs中的自定义规则的支持处于关闭状态。您可以在全局配置中使用item_allow_user_rules进行更改。
