spamassassin 不尊重 local.cf

spamassassin 不尊重 local.cf

我更新了我的/etc/spamassassin/local.cfspamassassin 檔案來更新一些評分規則。但是，即使重新啟動 spamassassin（通過服務）後，新分數也不會顯示在垃圾郵件中。事實上，該文件中的任何內容似乎都不會影響 spamassassin 的工作方式。

我使用 exim 作為我的 MTA，但這應該不重要。所有軟體包均透過 apt-get 安裝，最新版本為 14.04。

例如，我有這個：

score HTML_MESSAGE 2.0

定義在/etc/spamassassin/local.cf.我重新啟動了 exim 和 spamassassin。 spamassassing --lint顯示帽子檔案中沒有錯誤。然後又收到了另一封垃圾郵件：

0.0 HTML_MESSAGE           BODY: HTML included in message

在 X-Spam-Report 欄位中。

我運行了一下spamassassin -D < spam，cfg檔案的載入順序似乎是錯誤的：

Jun  8 13:34:07.300 [21668] dbg: config: read file /etc/spamassassin/local.cf
...
Jun  8 13:34:07.600 [21668] dbg: config: read file /var/lib/spamassassin/3.004000/updates_spamassassin_org/50_scores.cf
...
Jun  8 13:34:07.787 [21668] dbg: config: read file /var/lib/spamassassin/3.004000/updates_spamassassin_org/73_sandbox_manual_scores.cf
Jun  8 13:34:07.788 [21668] dbg: config: fixed relative path: /var/lib/spamassas
sin/3.004000/updates_spamassassin_org/local.cf
...

到底是怎麼回事？

基於評論森提曼：我嘗試了strace -f -e trace=file spamassassin -D < spam相同的結果：Spamassassin 在 local.cf 檔案之後讀取系統檔案。因此，丟棄任何分數變化。

根據評論，這是該local.cf文件，或多或少是普通文件。

endif # Mail::SpamAssassin::Plugin::Shortcircuit

整個輸出spamassassin -D對於這個來說太大了。然而，相關行在上面。如果您想了解更多信息，請告訴我要查找什麼，我會添加它。

答案1

問題是你正在設定HTML_MESSAGE得分內短路插入。但該插件預設情況下處於停用狀態。嘗試將分數設定在文件的最後一行，在短路 endif操作說明：

#   Some shortcircuiting, if the plugin is enabled
# 
ifplugin Mail::SpamAssassin::Plugin::Shortcircuit
# [...]
endif # Mail::SpamAssassin::Plugin::Shortcircuit

score HTML_MESSAGE 2.0

如果您希望啟用快速方式插件，您需要從/etc/spamassassin/v320.pre文件：

# Shortcircuit - stop evaluation early if high-accuracy rules fire
# 
loadplugin Mail::SpamAssassin::Plugin::Shortcircuit

答案2

SpamAssassin 的自述文件討論了 SpamAssassin 讀取其自身資料檔案的複雜方式。

從第 95 行開始閱讀： http://svn.apache.org/viewvc/spamassassin/branches/3.4/README?view=markup#l95

從閱讀內容來看，SpamAssassin（至少在原始的官方來源中）似乎沒有從

/etc/spamassassin/

根本不是，而是來自

/etc/mail/spamassassin/

嘗試將文件移到那裡！ ：D

答案3

在我的預設設定中，local.cf我讀到：

# These values can be overridden by editing ~/.spamassassin/user_prefs.cf
# (see spamassassin(1) for details)

您有使用者 spamassassin 設定檔 (~/.spamassassin/user_prefs.cf) 嗎？

也看看這個 perldoc：

perldoc Mail::SpamAssassin::Conf

在裡面使用者偏好我讀到的部分：

使用者首選項 以下選項可用於網站範圍（“local.cf”）和使用者特定（“user_prefs”）設定文件，以自訂 SpamAssassin 處理傳入電子郵件的方式。
