Problem with forwarding emails (SPF problem)

Hi,

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[...]_AT_fysik.su.se which forwards all email to carl_AT_w[...].com:
c[...]_AT_fysik.su.se -> carl_AT_w[...].com
The latter is hosted by one.com.

The sender, someone at xilinx.com, sent to c[...]_AT_fysik.su.se 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:

//
mx-v.one.com rejected a message that claimed an envelope sender address of p[...]_AT_xilinx.com.

mx-v.one.com received a message from smtp3.su.se (130.237.164.77) that claimed an envelope sender address of p[...]_AT_xilinx.com.

However, the domain xilinx.com has declared using SPF that it does not send mail through smtp3.su.se (130.237.164.77). That is why the message was rejected.
//

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

The one.com sys admin blames xilinx.com, the fysik.su.se admin doesn't have a clear idea of why this happens (except that it isn't the fault of su.se).

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 xilinx.com), however, myself and others can send emails to my su.se adress and they are forwarded without problems.

Thanks alot,
Carl
