By posting an example of the non-working filter code?  Otherwise how
do we know what's giong wrong?

Maybe you're filtering the wrong way?  

I use something like this and it's pretty good:

   require ["fileinto", "envelope"];
   require "imap4flags";
   require "regex";

   if header :contains "Sender" "linux-kernel-owner at
vger.kernel.org" {
     fileinto "lkml";
   }
   elsif header :contains "X-Mailing-List" "linux-kernel at
vger.kernel.org"
   {
     fileinto "lkml";
   }
   else {
     # The rest goes into INBOX
     # default is "implicit keep", we do it explicitly here
     keep;
   }


There's an implicit exit in each block as I recall and as my notes in
there show... I've got a whole bunch of other matches.  

Now where *my* rules fail at times is handling duplicates which were
went to a mailing list AND sent to me directly.  I need to fix it, but
haven't bothered to spend the time yet.

can be merged into one line if "List-Id: Dovecot Mailing List 
<dovecot.dovecot.org>" is used

posting to maillist will get dupes in return since message-id would not 
change, if any thing should be filtered as dupe delte the sent mail or 
do nothing :)

I'm sorry, question should have gone to roundcube list as it is 
roundcube plugin "manage_sieve" am using to make rules.
Don't see "elsif" in rule options which is likely what I want.

I'll search for the sieve config file on Debian bullseye.
