Hi Guys,

I have a mail server that keeps getting on CBL spam list due to  
incorrect  
mail server configuration. It says ‘localhost.localdomain’ error when I  
try  
to email their server with HALO request.

I am using ActionMailer. Where do I configure ActionMailer so that it is  
relaying the right information?

Thank you all,

–
