Rspamd 的 EXIM 配置中存在未知 ACL 條件/修飾符

我正在嘗試將 EXIM 配置為使用 Rspamd 作為垃圾郵件過濾器。我正在執行 Exim 4.87 版，並使用此處apt-get解釋的方法從儲存庫安裝 Rpsam 。然後我將Rspamd 文件中的建議配置添加到我的配置文件中：

begin acl

# configure Rspamd
# Please note the variant parameter
spamd_address = 127.0.0.1 11333 variant=rspamd   # error occurs here

acl_smtp_data = acl_check_spam

acl_check_spam:
 # do not scan messages submitted from our own hosts
 accept hosts = +relay_from_hosts

 # do not scan messages from submission port
 accept condition = ${if eq{$interface_port}{587}}

 # skip scanning for authenticated users
 accept authenticated = *

 # add spam-score and spam-report header when told by rspamd
 warn  spam       = nobody:true
       condition  = ${if eq{$spam_action}{add header}}
       add_header = X-Spam-Score: $spam_score ($spam_bar)
       add_header = X-Spam-Report: $spam_report

 # use greylisting available in rspamd v1.3+
 defer message    = Please try again later
       condition  = ${if eq{$spam_action}{soft reject}}

 deny  message    = Message discarded as high-probability spam
       condition  = ${if eq{$spam_action}{reject}}

 accept

當我嘗試重新啟動 Exim 時，我收到以下錯誤消息：

error in ACL: unknown ACL condition/modifier in "spamd_address = 127.0.0.1 11333 variant=rspamd"

這是指我上面發布的配置程式碼的第 4 行：spamd_address = 127.0.0.1 11333 variant=rspamd. 我在官方 Exim 文件中找到了完全相同的行。所以它應該工作。之前有人在配置 Exim 以使用 Rspamd 時遇到過這個問題嗎？

我正在使用 Ubuntu：

$ uname -a
Linux calais 4.4.0-36-generic #55-Ubuntu SMP Thu Aug 11 18:01:55 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

將spamd_address = 127.0.0.1 11333 variant=rspamd指令放在 ACL 部分之外。一般來說，它應該放在配置的開頭，然後再定義 ACL、服務、路由器和傳輸。
