The most likely way to succeed is to override Mage_Customer_Model_Customer and provide your own getGroupId() method. This method should check the domain of the email address ($this->getEmail()) and then both set and return the ID of the group. If it doesn't recognise the domain then pass it back to the parent to be processed as normal.
