如何使用 sa-exim 和 exim4 将垃圾邮件移至用户的垃圾邮件文件夹？

我已经在 Ubuntu LTS 安装上安装并成功配置了 exim4 和 sa-exim。垃圾邮件已成功标记：

X-SA-Exim-Connect-IP: 89.238.139.198
X-SA-Exim-Mail-From: hertaqcrqsaa@xxx

但电子邮件仍会发送到用户的收件箱 Maildir。我该如何将其更改为发送到用户的 .Spam Maildir？

答案1

我不知道 exim4 和 sa-exim 是否可以自动为您做到这一点。其他人可能会对此发表看法。

但是，在用户的计算机上，在 Thunderbird 中，您可以使用消息过滤器将垃圾邮件移至垃圾邮件文件夹。创建一个新的消息过滤器，如下所示...（如果您不希望匹配 X-Spam-Status，您可以创建一个特殊标志，例如，X-Spam-Flag）...

我自己通过优秀的进出口维基：

首先，您必须创建一个/etc/exim4/conf.d/router/899_exim4-config_local_user_spam包含以下内容的文件：

### router/900_exim4-config_local_user_spam                               
#################################                                         

# This router matches local user mailboxes. If the router fails, the error
# message is "Unknown user".                                              

local_user_spam:                                                          
  debug_print = "R: local_user_spam for $local_part@$domain"              
  driver = accept                                                         
  domains = +local_domains                                                
  check_local_user                                                        
  local_parts = !www:!root:!nobody:!postmaster:!abuse:!admin              
  transport = maildir_spam_delivery                                       
  condition = ${if def:h_X-Spam-Flag: {true}}                             
  cannot_route_message = Unknown user

这将在编号为 900 的本地用户路由器之前进行匹配。这确保垃圾邮件将使用以下传输方式传递。

/etc/exim4/conf.d/transport/30_exim4-config_maildir_spam_delivery使用以下内容创建传输：

### transport/30_exim4-config_maildir_spam_delivery                      
#################################                                        

# Use this instead of mail_spool if you want to to deliver to Maildir in 
# home-directory - change the definition of LOCAL_DELIVERY               
#                                                                        
maildir_spam_delivery:                                                   
  debug_print = "T: maildir_spam_delivery for $local_part@$domain"       
  driver = appendfile                                                    
  .ifdef MAILDIR_HOME_MAILDIR_LOCATION                                   
  directory = MAILDIR_HOME_MAILDIR_LOCATION/.Junk                        
  .else                                                                  
  directory = $home/Maildir/.Junk                                        
  .endif                                                                 
  .ifdef MAILDIR_HOME_CREATE_DIRECTORY

  .ifdef MAILDIR_HOME_CREATE_FILE                                        
  create_file = MAILDIR_HOME_CREATE_FILE                                 
  .endif

  .ifdef MAILDIR_HOME_DIRECTORY_MODE                                     
  directory_mode = MAILDIR_HOME_DIRECTORY_MODE                           
  .else                                                                  
  directory_mode = 0700                                                  
  .endif                                                                 
  .ifdef MAILDIR_HOME_MODE                                               
  mode = MAILDIR_HOME_MODE                                               
  .else                                                                  
  mode = 0600                                                            
  .endif                                                                 
  mode_fail_narrower = false                                             
  # This transport always chdirs to $home before trying to deliver. If   
  # $home is not accessible, this chdir fails and prevents delivery.     
  # If you are in a setup where home directories might not be            
  # accessible, uncomment the current_directory line below.              
  # current_directory = /

这基本上是默认传输的副本maildir_home，仅附加/.Junk到 maildir 名称。

我确信 exim4 可以通过一些 if 和 else 更优雅地完成此操作，但我的 exim foo 还不够好。欢迎任何 exim 专业人士为该解决方案做出贡献。
