Automatic e-mail account configuration in Thunderbird 2

Question

I'm trying to automatically configure Thunderbird e-mail accounts that are in my domain and its subdomains (eg. [e-mail], [e-mail]). E-mail client doesn't have access to the internet and because of necessary add-on I have to use Thunderbird 2.0.0.6.

Below are my configuration files:
1. rdf (based on https://developer.mozilla.org/en-US/docs/Mozilla/Projects/Thunderbird/Thunderbird_ISP_hooks) - adds account type to choose in the account setup but only for one domain
2. xml (https://developer.mozilla.org/en-US/docs/Mozilla/Thunderbird/Autoconfiguration) - doesn't work (as it probably should - it's advertised to be included in Thunderbird 3 and newer)

My questions:
- is there a way to define subdomains in .rdf file
- is it possible to make xml autoconfiguration work with Thunderbird 2

This is example rdf::
