Hi folks,

I have added a domain in my nameserver with the following configuration:
SOA	ns.inwx.de foo at bar.de 2009073103
NS	ns.inwx.de
NS	ns2.inwx.de
NS	ns3.inwx.de

After this I have checked the entries with dig, that everything is correct.

-----------------------------------------------------------------
$ dig @ns.inwx.de spf-record-test.de ANY

; <<>> DiG 9.5.1-P2 <<>> @ns.inwx.de spf-record-test.de ANY
; (1 server found)
;; global options:  printcmd

Next step..
Now I have added a SPF record.
SPF	v=spf1 -all

And checked the entries with dig again.

-----------------------------------------------------------------
$ dig @ns.inwx.de spf-record-test.de ANY

; <<>> DiG 9.5.1-P2 <<>> @ns.inwx.de spf-record-test.de ANY
; (1 server found)
;; global options:  printcmd

-----------------------------------------------------------------

After adding a SPF record, it isn't possible to dig the domain.
I don't get any records of the domain. After removing the SPF record it is
possible again.
It seems to be a problem with pdns and SPF records.

Furthermore it seems that some mailservers can't deliver e-mails because the
nameserver lookup deferred, if the SPF record is set.

Does somebody know, what I can do to solve the problem?
Or maybe it is a bug?!

The used pdns-server version is 2.9.22-1.

$ dig -v
DiG 9.5.1-P2

Thanks,

shion
