class QuestionMailer < ActionMailer::Base
  default :to => "%mail@mydomain" #gmail for domains

  def ask(message)
    @content = message.content

    unless message.name.nil? or message.name.empty?
      from = "#{message.name} <#{message.email}>"
    else
      from = message.email
    end

    mail(:subject => message.subject,:from => from)
  end
end

在我的控制器中,我有以下几行：

if @question.valid?
  QuestionMailer.ask(@question).deliver
  redirect_to root_url,:notice => "Сообщение отправлено"
else

Production.rb：

config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { :host => '%mydomain%' }

ActionMailer::Base.smtp_settings = {
  :address        => "smtp.sendgrid.net",:port           => "25",:authentication => :plain,:user_name      => ENV['SENDGRID_USERNAME'],:password       => ENV['SENDGRID_PASSWORD'],:domain         => ENV['SENDGRID_DOMAIN']
}

我一开始没有这个配置,但是当我没有收到电子邮件时,我添加了它.

问题是,Heroku日志说,相应的视图已经呈现,但我没有收到电子邮件.因为我使用sendgrid,我无法在本地测试它.

UPD

注意自我.为域帐户创建Gmail后,请不要忘记您的DNS设置. > _<
