SPF Notification question

Greetings.  I am pretty sure I have our SPF (TXT) record set up properly in DNS, but every so often we get an undeliverable message with an SPF link similar to:

Please see http://www.openspf.org/Why?xxxxxxxxxxxx

The resulting suggestion from Openspf.org is:

MX1 rejected a message from a mail server claiming to be mail.our_domain.org.

MX1 received a message from mail.our_domain.org (xx.x.xxx.xx) from a mail server claiming to be mail.our_domain.org.

The domain mail.our_domain.org has not published an SPF policy. It is possible that the receiving mail server refuses all mail from domains that do not have an SPF policy.

My guess is that the recipient's mail server or hosted filtering is doing a reverse DNS for:  mail.our_domain.org  or their SPF check is mistaking our "domain" as:  mail.our_domain.org  .... instead of correctly identifying our domain as:   our_domain.org

Suggestions ?  Anything we should change or is this a misconfiguration on the recipient's side ?

Thanks much.
