Hello.
On the mail server, I configured addition of the
Authentication-Results header with authentication check results.
I noticed that emails from the dovecot.org server have an incorrect ARC
signature:
Authentication-Results: ...;
dkim=pass header.d=dovecot.org header.s=... header.b=...;
dkim=fail ("body hash did not verify") header.d=... header.s=... header.b=...;
arc=reject ("signature check failed: fail, {[1] = sig:dovecot.org:reject}");
spf=pass (...: domain of "dovecot-bounces+...=...@dovecot.org" designates ... as permitted sender) smtp.mailfrom="dovecot-bounces+...=...@dovecot.org";
dmarc=pass (policy=reject) header.from=dovecot.org
