I run rspamd on FreeBSD, and tested this to see if it's a problem for 
more people;

Description    :
Rspamd is fast, modular and lightweight spam filter. It is designed to 
work
with big amount of mail and can be easily extended with own filters 
written in
lua.

# jexec rspamd pkg info | grep lua
luajit-devel-2.1.0.20240821    Just-In-Time Compiler for Lua

# jexec rspamd rspamadm configdump replies
*** Section replies ***
message = "Message is reply to one we originated";
expire = 432000;
key_prefix = "rr";
symbol = "REPLY";
servers = "10.0.0.100";

*** End of section replies ***


# grep -v "^ *\(--\|#\)" modules.d/replies.conf

replies {
   expire = 86400;
   key_prefix = "rr";
   message = "Message is reply to one we originated";
   symbol = "REPLY";

   .include(try=true,priority=5) "${DBDIR}/dynamic/replies.conf"
   .include(try=true,priority=1,duplicate=merge) 
"$LOCAL_CONFDIR/local.d/replies.conf"
   .include(try=true,priority=10) 
"$LOCAL_CONFDIR/override.d/replies.conf"
}

# grep -v "^ *\(--\|#\)" local.d/replies.conf

   servers = "10.0.0.100";
   expire = 5d;
   key_prefix = "rr";
   message = "Message is reply to one we originated";
   symbol = "REPLY";

I sent a mail somewhere, then replied, and, yes, in the headers there is 
the symbol "REPLY"

Everything seems to be working just fine.
