Mail rejected by GMX

Dear all

We recently implemented SPF records for verivox.com, verivox.de and
verivox.pl, as follows

v=spf1 mx:vxw-mx-01.verivox.de mx:vx-ffm01-mxns.verivox.de
mx:mx-ffm-01.verivox.de ~all

The three MX entries reflect the 3 servers which are authorised to send
from the above domains.

Today we received notice that GMX rejected a mail sent from the server
vx-ffm01-mxns.verivox.de, the reason given was that the SPF record did
not authorise this server:
http://www.openspf.org/Why?id=Tarif-Information%40verivox.com&ip=83.137.
184.242&receiver=spfquery

Can you help us to adjust the SPF record to avoid this situation? What
did we do wrong?

Please note, the SPF records have been removed again temporarily, until
we can come up with a solution.

Many thanks, best regards from Germany

It's a very simple mistake.

You intended to specify "The MXes called ...". You actually specified "The
MXes *for* ...".

vxw-mx-01.verivox.de has no mx record. Neither does
vx-ffm01-mxns.verivox.de or mx-ffm-01.verivox.de.

The simplest solution would be to change your record to :-

v=spf1 vxw-mx-01.verivox.de vx-ffm01-mxns.verivox.de mx-ffm-01.verivox.de
~all

...Although you might be better off changing those to IP addresses if they
don't change ver often.

Which of course isn't a valid record, this however is probably what you meant:

v=spf1 a:vxw-mx-01.verivox.de a:vx-ffm01-mxns.verivox.de
a:mx-ffm-01.verivox.de ~all

Noting that there's no guarantee that these are the only servers your
mail would exit from.
