Hello people

I have an app that I deploy to multiple sites.  
In this app, I send out email notifications.

In my actionmailer I have  
ActionMailer::Base.smtp\_settings = {  
:address =\> ‘smtp.[domain]’,  
:port =\> 25,  
:domain =\> ‘smtp.[domain]’,  
:user\_name =\> ‘noreply@[domain]’,  
:password =\> ‘[password]’,  
:authentication =\> :plain

}

I know in the controller, I can do a request.domain(1) to get the  
[domain.com](http://domain.com), but I’m not in the controller. If my understanding is  
correct, this is ran once as the mongrels are starting up. How would  
I determine the domain name without the request object?

Thanks for your help.

Kevin
