Problem with forwarding emails (SPF problem)


This is rather a question from a "user" than from a sys admin, but I think this forum is apropriate for the question.

I have an adress with automatic email forwarding and for some senders (two hietherto), emails are bouncing. This has really created a lot of problems those two time so I need to solve this matter.

(Below I have replaced parts of personal email adresses with [...].)

I have an adress c[...] which forwards all email to carl_AT_w[...].com:
c[...] -> carl_AT_w[...].com
The latter is hosted by

The sender, someone at, sent to c[...] but got a bounce. The complete bounce message is included under this message.

When following the link to the openspf page I can read, among other things, the following:

// rejected a message that claimed an envelope sender address of p[...] received a message from ( that claimed an envelope sender address of p[...]

However, the domain has declared using SPF that it does not send mail through ( That is why the message was rejected.

So apparently my ISP doesn't want to recieve the email.

The sys admin blames, the admin doesn't have a clear idea of why this happens (except that it isn't the fault of

What is really causing the bounces and what could I do to fix this? The problem seems to persist for all emails sent by this particular sender (at, however, myself and others can send emails to my adress and they are forwarded without problems.

Thanks alot,
