[Rspamd-Users] Milter headers module : extended_spam_headers not working

[Eric de la Musse]

Hello,

I can't get the extended_spam_headers parameter of the milter headers
module to work (the headers 'X-Rspamd-Queue-Id', 'X-Spamd-Result' and
'X-Rspamd-Server' don't appear on external origin emails).

The MTA used is Opensmtpd on FreeBSD (opensmtpd-7.3.0_3 package) with
the rspamd filter (opensmtpd-filter-rspamd package).

rspamd is properly called by opensmtpd because spam is correctly marked
with the 'X-Spam: yes' header.

Content of the local.d/milter_headers.conf file:

    extended_spam_headers = true;

It's as if the milter header module wasn't called because if I add to
the local.d/milter_headers.conf file:

    use = ["stat-signature"];
    routines {
        stat-signature {
            header = 'X-Stat-Signature';
            remove = 0;
        }
    }

The 'X-Stat-Signature' header doesn't appear either.

I imagine the solution must be very simple but after several hours of
research and various tests I no longer know how to solve the problem...

I don't see anything in the opensmtpd or rspamd logs that would be
related to the problem... even after adding in local.d/logging.inc:

    level = "debug";
    debug_modules = ["milter_headers"];

# grep milter /var/log/rspamd/rspamd.log

Do you have any idea? How can I effectively debug this problem?
