爲什麼沒有：from參數在我的Rails actionmailer上工作？

Question

我也跟着在Rails的發送電子郵件的教程，我有這在我的production.rb

ActionMailer::Base.smtp_settings = { 
    :tls   => true, 
    :address  => 'smtp.gmail.com', 
    :port   => 587, 
    :domain   => 'http://myapp.heroku.com', 
    :authentication => :plain, 
    :user_name  => 'mygmailusername@gmail.com', 
    :password  => 'mypassword' 
    } 

這的ActionMailer

mail(
    :to => user.email, 
    :from => "noreply@myapp.heroku.com", 
    :subject => "Welcome to My App", 
    :body => "Please activate your account by going to this address: \n" + 
       "http://myapp.heroku.com/" + 
       user.username + "/activate/" + user.activation_key 
    ) 

當發送一封電子郵件，該電子郵件來自mygmailusername@gmail.com而不是來自noreply@myapp.heroku.com。我怎樣才能解決這個問題？

Answer 1

你不能，GMail確實允許你發送郵件給其他人（原因很明顯）。
