Hello,

I use the metadata_exporter.conf approach for this purpose. Rejected and soft rejected end up in /var/spool/mail/quarantine/reject or soft_reject.

8<-----------8<---------
#
# local.d/metadata_exporter.conf
#
# script zum Abspeichern von rejected emails in eine quarantine # # Define custom selector(s) #
   custom_select {
     mine = <<EOD
return function(task)
   local action = task:get_metric_action('default')
   return (action == 'reject' or action == 'soft reject') end EOD;
   }
   custom_push {
     mine = <<EOD
return function (task, data, rule)
   folder = task:get_metric_action('default')
   folder = folder.gsub(folder, ' ', '_')
   local rspamd_logger = require "rspamd_logger"
   rspamd_logger.infox(task, 'METATEST %s', folder)
   local rspamd_util = require "rspamd_util"
   rspamd_util.mkdir('/var/spool/mail/quarantine/' .. folder)
   file = io.open('/var/spool/mail/quarantine/' .. folder .. '/' .. task:get_queue_id(), "w")
   file:write(tostring(data))
   file:close()
end
EOD;
   }

   rules {

     quarantine {
       selector = "mine";
       formatter = "default";
       backend = "mine";
     }
   }
8<-----------8<---------

and in worker-proxy.inc I have
8<-----------8<---------
...
discard_on_reject = false;    # Discard message instead of rejection
#
quarantine_on_reject = false; # Tell MTA to quarantine rejected messages ...
8<-----------8<---------

Maybe this is what you are looking for?
