Hi All,

I am looking for implementing domain keys for authenticating outgoing  
mails through my rails application to prevent the mails going in  
spams.

I am using SMTP for sending mails using Action Mailer through my  
application.

Do any one know how to implement in rails or can provide any source or  
link or it ?

Also does this implementation is platform independent (Does it work  
same in Windows and Linux)??

Thanks in advance.

Piyush.
