Hi,

I’ve got some domains , lets say [example.com](http://example.com) and [example.de](http://example.de) and I want  
that the link in a ActionMailerView contains the correct localized  
host e.g. with \<%= @root\_url %\> .  
Currently the host is set in the environment.rb with  
“config.action\_mailer.default\_url\_options = { :host =\>  
“[example.com](http://example.com)” }”.  
How can I set the host dynamically and localized? I’m sending my mails  
though a Delayed Job.  
Thanks.

greetings  
LeonS

I think i need to determine the “request.host\_with\_port” in the  
controller and pass it as an argument to the notifier and to the  
delayed Job.  
Is there a better way to do that?
