I am a little bit confused.

- why not verify dkim ? It seems fine for your message. I get:

Received-SPF: Pass (mailfrom) identity=mailfrom; client-ip=94.237.105.223; helo=talvi.dovecot.org; envelope-from=dovecot-bounces at dovecot.org; receiver=<UNKNOWN>
Authentication-Results: OpenDMARC; dmarc=pass (p=none dis=none) header.from=junc.eu
Authentication-Results: vps2.salort.eu;
	dkim=pass (2048-bit key; secure) header.d=junc.eu header.i=@junc.eu header.a=rsa-sha256 header.s=default header.b=CC9G/2tV;
	dkim-atps=neutral

- Is it useful to install something besides OpenDMARC (OpenARC ?), or some dedicated OpenDMARC configurations, for the ARC-Seal to be useful ?

I suppose SPF works because the Envelope is correctly set to dovecot.org address, so I don't understand the problem the OP was mentionning.

Cheers,
