Rails Action Mailer simple settings

def post_notification(recipients, post)
       @recipients = recipients
       @from = post.author.email_address_with_name
       @headers[“bcc”] = SYSTEM_ADMINISTRATOR_EMAIL
       @headers[“reply-to”] = “notifications@example.com”
       @subject = “[#{post.account.name} #{post.title}]”
       @body[“post”] = post
       @charset = “iso-8859-1”

end 

  
Rails 4 mailer changes 

 in rails 4 for each object for sending an email we can change an SMTP settings. means we can do a dynamic smtp settings.by overriding the following method

def my_mailer(receiverobject, smtpobject)
   mail to: receiverobject.email, subject: “Welcome!”,
     delivery_method_options: { user_name: smtpobject.smtp_user,
                             password: smtpobject.smtp_password }

end

this will ensure that your settings from environments/production.rb will be override.

we can get an array of email sents through Action Mailer . mostly used in progress bar like functionality like suppose in view we wanted to show a progress bar with the count of how many emails has been sent then we can get this through this ActionMailer::Base.deliveries method
