Actionmailer and postfix settings

Hi,

I am having problems configuring my actionmailer to work with postfix.

I followed this tutorial: AffiliatesAdminPanel

and i got the server set up.

at first i fixed the mail settings to work with gmail using this tutorial:

http://www.danielfischer.com/2008/01/09/how-to-use-gmail-as-your-mail-server-for-rails/

and my app worked with gmail.

but now i want it to work with my newly built email server. I read somewhere if your server has tls u have to do something special with actionmailer for it to work so i am relying on fischer's workaround.

so i inputed this into the mailer.yml file that danielfischer created:

    :address: localhost     :port: 25     :domain: localhost     :user_name: mailer@mydomain.com     :password: secret     :authentication: :plain     :tls: true

Should i have used mydomain instead of localhost? I just can't seem to get it to connect there is nothing in my tail - f /var/log/maillog error Please help!
