mailing list error when no mailing list is installed?

[michaellunsford]

I created a subdomain called lists.domain.com -- but if I want to make any changes in the subdomain setup, I get the following error:

Unable to update hosting preferences: Incorrect subdomain name lists.(domain.com), on domain (domain.com) the Mailing lists are enabled.

additional information... the mailing lists show as enabled for the domain. This shows up in the resources section at the botton of the domain's main control panel page. It also says I am using "0" and allowed "unlimited." There is no place I can find to turn this feature on or off, though.

The server page has a mailman button that is grayed out. I can't find any other reference to mailing lists anywhere on the server.

Thoughts?
