[Rspamd-Users] How to change greylist module threshold (or force it) for certain mails ?

[Michal Soltys]

Hi,

So far I've tried roughly three ideas, but none so far worked correctly:

1) via multimap in prefilter mode

forced_greylist {
   type = "rcpt";
   filter = "email:user";
   map = [ 'testg' ];
   symbol = "RCPT_TESTG";
   description = "Greylist force";
   score = 0.0;
   prefilter = true;
   action = "greylist";
}

This caused any emails addressed to testg@ to end in a greylist "loop" - 
any retries attempted by the remote server (after the required 5min 
timeout) ended again in a greylisted state.

2) via settings

boost_greylist {
         id = "boost_greylist";
         priority = high;
         rcpt = "/^testg@/";
         symbols = [ RCPT_TESTG ];
         apply = {
                 actions {
                         greylist = -5.0;
                 }
         }
}

This correctly added RCPT_TESTG symbol to all mails addressed to testg@ 
- but the -5.0 adjustment had no effect whatsoever.

3) via settings + force actions

In addition to 2:

rules {
   force_greylist {
     action = "greylist";
     expression = "RCPT_TESTG";
     honor_action = [ "add header", "reject" ];
   }
}

This ends same as in case #1 - endless greylist "loop".



Is there any way to actually make this work ?
