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
