ARC test can be skipped if ORIGINATING dkim signed DKIM signature gives 
PASS

your mail here gives DKIM PASS in perl Mail::DKIM

but

ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; 
d=dovecot.org;
  s=arc; t=1615272934;
  h=from:from:reply-to:subject:subject:date:date:message-id:message-id:
  to:to:cc:mime-version:mime-version:content-type:content-type:
  content-transfer-encoding:content-transfer-encoding:
  in-reply-to:in-reply-to:references:references:dkim-signature;

is with double headers sign in ARC :(

is owners listen here ?
