Thanks for the quick reply, I think I isolated the issue (and to me, it looks 
like a bug!)

I got to testing this thoroughly when I noticed that all amazon.de 
notifications were dropped for some time now.
What I found is this:

Disabling spf-checking by setting /var/qmail/control/spfbehaviour to 0

all emails pass. When left on the default (3) I have the problem.

Now, amazon plays by the rules:

checking amazon.de (! important that this is the German one!) for SPF records 
yields:

v=spf1 include:amazon.com ~all 
spf2.0/pra include:amazon.com ~all 

And this is where I think the problem lies.
The system is able to interpret the SPF policy, but does not seem to look up 
the 'include' part...

For in amazon.com records, I found

The TXT records found for your domain are:
v=spf1 ip4:207.171.160.0/19 ip4:87.238.80.0/21 ip4:72.21.192.0/19 
ip4:194.154.193.192/27 ip4:194.7.41.152/28 ip4:212.123.28.40/32 
ip4:203.81.17.0/24 ip4:72.21.212.0/25 ip4:199.255.192.0/22 ~all 

spf2.0/pra ip4:207.171.160.0/19 ip4:87.238.80.0/21 ip4:72.21.192.0/19 
ip4:194.154.193.192/27 ip4:194.7.41.152/28 ip4:212.123.28.40/32 
ip4:203.81.17.0/24 ip4:72.21.212.0/25 ip4:199.255.192.0/22 ~all 

and the matching IP address is part of the ones listed above.

So, where would I look for the SPF-related code in qmail?

Or should I disable it and enable in spamassassin instead? (which could be an 
interim work-around, I guess)..


What do you think?
