About ActionMailer and condiguration of action mailer.

ActionMailer allows you to send email from your application, when you generate a action mailer
using following command: -
script/generate mailer Notifier
a action mailer class(inside model folder) and view generate.

Mailer methods have the following configuration methods available.

• recipients - Takes one or more email addresses. These addresses are where your email will be delivered to. Sets the To: header.
• subject - The subject of your email. Sets the Subject: header.
• from - Who the email you are sending is from. Sets the From: header.
• cc - Takes one or more email addresses. These addresses will receive a carbon copy of your email. Sets the Cc: header.
• bcc - Takes one or more email address. These addresses will receive a blind carbon copy of your email. Sets the Bcc header.
• sent_on - The date on which the message was sent. If not set, the header wil be set by the delivery agent.
• content_type - Specify the content type of the message. Defaults to text/plain.
• headers - Specify additional headers to be set for the message, e.g. headers ‘X-Mail-Count’ => 107370.

Configuration
1. First you need to configure action mailer with your application.
open environment.rb file or you can write it in a production/development file also.
after the 'Rails::Initializer.run do |config|' block
paste the below mention code

ActionMailer::Base.raise_delivery_errors = true #You may also turn exception raising on and off.
ActionMailer::Base.delivery_method=:smtp
ActionMailer::Base.smtp_settings = {
:address => "smtp.yourserver.com",
:port => 25,
#:domain => "www.mywebsite.com"
:user_name => "username",
:password => "password",
:authentication => :login # :plain, :login or :cram_md5
}
:domain is the name sent to the SMTP server during the handshake. It will be used to form the first “Received:” header, which spam filters usually check.
