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?
