ActionMailer::Base.server_settings = {
:address => "smtp.somesite.com",
:port => 25,
:domain => "somesite.com",
:authentication => :login,
:user_name => "username",
:password => "password",
}
# following line for to use a view for our email format.
ActionMailer::Base.default_content_type = "text/html"

Generate email model by typing :

script/generate mailer Emailer


3) Edit the model

class Emailer < ActionMailer::Base
def contact(recipient, subject, message, sent_at = Time.now)
@subject = subject
@recipients = recipient
@from = 'no-reply@somedomail.com'
@sent_on = sent_at
@body["title"] = 'This is title'
@body["email"] = 'sender@somedomain.com'
@body["message"] = message
@headers = {}
end
end


4)

create a file called app/views/contact.rhtml
add the following. lines
