In one version you also havedkim=pass (1024-bit key; unprotected)
header.d=amazon.de
header.i=@marketplace.amazon.de header.b=AOE4Rr31
which is an aligned pass because marketplace.amazon.de inherits amazon.de's
record which doesn't specify strictness of alignment and therefore defaults to
relaxed.
You actually have both multiple results in a single Authentication-Results
header and multiple Authentication-Results headers.

in which sense?
- RFC5322.From is "amazon.DE"
- SPF pass for "bounces.amazon.COM"
- DKIM pass for "amazonses.COM"
so neither SPF nor DKIM is aligned. according to the published record
the message should be quarantined:
$ opendmarc-check amazon.de
DMARC record for amazon.de:
Sample percentage: 100
DKIM alignment: relaxed
SPF alignment: relaxed
Domain policy: quarantine
Subdomain policy: unspecified

it's a bunch of milters plugged to postfix:
smf-spf + opendkim + opendmarc

Oh, never thought about that. I know that scheme (separate A-R header)
since years. You're right. they may be combined to only one A-R.
But the way I use it they insert multiple A-R header.
Would be good to hear from Murray if this is the intended use-case for
OpenDMARC. In general I know OpenDMARC simply as an A-R header parser.
So my assumptions could not be completely wrong...
