Hi, just a quick update. The size of the email is not the reason. Amavis transmits emails completely. The limitation ($sa_mail_body_size_limit = 200*1024; ) is probably intended for its own checks. I used the content of the firstmallorca email as a template for a new email and sent it via my servers. DKIM is valid for opendkim and SA DKIM. A diff between the raw email (stored after opendkim) and the email stored at the end also showed that only a Delivered-To and a Received line were added to the header. So there must be a special case that occurs when such a news email is sent via Mailchimp, which unlike opendkim the DKIM check used by SA cannot handle. When I got a mail confirmation from firstmallorca, the mail was sorted into the junk folder too: Authentication-Results: mx1.txbweb.de; dmarc=fail (p=reject dis=none) header.from=firstmallorca.com Received: from backend.firstmallorca.com (backend.firstmallorca.com [88.99.212.108]) But spf is "v=spf1 include:_spf.google.com ~all" I think I have to configure more tolerance for "spanish" mails :) Best regards Thomas B.
