Multiple Domains inside RT?

Hi List,

I’m trying to determine the best way to run multiple domains inside an RT system. I have multiple queues set up currently, and would like it so that when a user corresponds with a particular queue, all email correspondance is marked with a different domain than the one specified in RT_SiteConfig.pm. Is this possible?

I tried going down the Multiple Instances path, but fastcgi under apache2 is giving me nothing but problems hanging after startup, etc.

If there is a way to do this without having to run multiple instances of RT, that would be ideal, any feedback is appreciated.

Thanks
