Hallo,

I got a message from an ESP. opendmarc marked it as not passing dmarc:

From: Zalando-Lounge <[email protected]>
Authentication-Results: mta.example.org; dmarc=fail header.from=service3.zalando-lounge.de
Authentication-Results: mta.example.org; dkim=pass
         reason="1024-bit key; unprotected key"
header.d=service3.zalando-lounge.de [email protected]
         header.b=CoXLl/BB; dkim-adsp=pass; dkim-atps=neutral
Authentication-Results: mta.example.org;
spf=pass smtp.mailfrom=<[email protected]> smtp.helo=pmta43117.emarsys.net

I contacted the sender. He presented header from gmail. They marked such mails with dmarc=pass:
Received: from pmta43113.emarsys.net (pmta43113.emarsys.net.
[91.211.243.113]) by mx.google.com with ESMTP id z8si4213575eee.359.2013.07.16.23.28.46
    for <[email protected]>; Tue, 16 Jul 2013 23:28:46 -0700 (PDT)
Received-SPF: pass (google.com: domain of [email protected]
    designates 91.211.243.113 as permitted sender)
    client-ip=91.211.243.113;
Authentication-Results: mx.google.com;
    spf=pass (google.com: domain of [email protected] designates
    91.211.243.113 as permitted sender) [email protected];
    dkim=pass [email protected];
    dmarc=pass (p=REJECT dis=NONE) d=service3.zalando-lounge.de

$ dig _dmarc.service3.zalando-lounge.de txt +short
"v=DMARC1\; p=reject\; adkim=s\; aspf=r\; rf=afrf\; pct=100\;"

dkim is aligned in strict mode, spf does not match so it's not aligned.

I found a message from Franck (http://www.dmarc.org/pipermail/dmarc-discuss/2012-August/001310.html) "As long as one authentication mechanism passes and is aligned then DMARC passes"

But here relaxed spf alignment is expilicit requested...

Who is wrong?

Andreas
