Rails 4 already has before_filter and after_filter callbacks. For Rails 3 users, it's surprisingly simple to add them: just include AbstractController::Callbacks. This mimics the change to Rails 4 which apart from comments and tests, just included Callbacks.

class MyMailer < ActionMailer::Base
  include AbstractController::Callbacks

  after_filter :check_email

  def some_mail_action(user)
    @user = user
    ...
  end

  private
  def check_email
    if @user.email.nil?
      mail.perform_deliveries = false
    end
    true
  end

end
