Despite having what I believe to be the correct settings, all of my domains currently display all of my content.

The links to the articles contain the proper domain names, but the content displayed is the same across all domains.

In essence, every domain acts like the default domain. Very frustrating.

Settings:

Force default domain is unchecked (keeping it checked plays hell with any module)
All: all domains, including the default, see only their own content

Each domain has "Match every page except the listed pages." selected -

I've had to make one minor change to the default install of this module, stripping 'www.' from the domain so both www.domain.com and domain.com displayed content.

Can anyone point me in the right direction?
