[Rspamd-Users] ARC-signing does not happen

I cannot get rspamd to set ARC signatures to my outgoing mails. I have
a list server so both incoming and outgoing mails are passed through
the milter. Incoming mails should be ARC-verified (if applicable) and
outgoing should be signed. I know that the outgoing milter works as it
adds DKIM signatures which works fine. If there is any resource on how
to do this or if someone has a tip on how to proceed I'd be very

I run postfix as MTA and the following config for ARC in rspamd
(domain name changed to protect the innocent):

/etc/rspamd# rspamadm configdump arc

use_esld = true;
allow_hdrfrom_mismatch = true;

try_fallback = true;

    example.net {
        path = "/var/rspamd/dkim/example.net.dkim.key";
        selector = "dkim";

use_redis = false;
allow_username_mismatch = true;

use_domain = "recipient";
