Last week I updated to Ubuntu 16.04. So I have a new Postfix version
(3.1.0) as well as a new pdns_recursor version (4.0.0-alpha2).
Since this update Postfix does not receive correct answers for a
particular query anymore. Concretely, queries for A entries of
Office365 mail servers.
For example if Postfix asks for the A entry of
nxp-com.mail.protection.outlook.com, pdns_recursor returns to Postfix
that there does not exists a A record.
However, if I manually do this query with dig, I do get an correct
answer. Please see the logs at the end of the mail.
Besides the queries of Office365 mail servers, the rest is working
fine. I have no idea how to track down that issue? Is there any
setting in pdns_recursor I have to change?
Postfix might be asking for DNSSEC, which is finiky in the alpha
version Ubuntu pulled in. Can you install 4.0.1 from our
repositories[1] and try again? 4.0.1 has about 5 months more
development time in it.
Thanks a lot!
Updating to 4.0.1 solved the problem for me.
Regards,
Michael
