Spam filter... submission could be spam

Small private Drupal site... I am currently the only user updating content. My user is an administrator. I am trying Mollom out, turned on protection for everything.

I always get this message:
We are sorry, but the spam filter on this site decided that your submission could be spam. Please fill in the CAPTCHA below to get your submission accepted.

I thought it was supposed to let it fly if the Mollom servers don't think it's spam, or give a message if "unsure". Does this mean somehow my user is being seen as possible spam? If so how can I correct this?

In the access control page

In the access control page you can select which user roles will not be checked by Mollom.

If you however always get the above message, whatever the content, this might signify that there is a problem with the IP settings of your site. Make sure that you enable the correct Drupal settings if you are behind a proxy as this will interfere with the Mollom module.

We use the poster's IP to build a sender reputation. If you are behind a proxy, it is possible that you constantly send the proxy's IP to Mollom, which will lead to a wrong reputation for legit users.
