Rails DeviseのReply-Toを消す

DeviseのデフォルトだとFromがReply-Toになる

デフォルト設定のままだとReply-ToにFromのアドレスが入ってしまう。
邪魔だなあ。どうにかしたいなあ。そんなあなたへの解です。

この状態のinitializerはこちら

config/initializers/devise.rb

Devise.setup do |config|
  # ==> OmniAuth
  # Add a new OmniAuth provider. Check the wiki for more information on setting
  # up on your models and hooks.
  google = Rails.application.secrets.google
  config.omniauth :google_oauth2, google[:client_id], google[:client_secret], { name: :google, scope: %w[email profile] }
  config.mailer_sender = '"TEST" <[e-mail]>'
  config.confirm_within = 1.day
end

対応

Devise::Mailer.default reply_to: nilを追記するだけ。

config/initializers/devise.rb

Devise.setup do |config|
  # ==> OmniAuth
  # Add a new OmniAuth provider. Check the wiki for more information on setting
  # up on your models and hooks.
  google = Rails.application.secrets.google
  config.omniauth :google_oauth2, google[:client_id], google[:client_secret], { name: :google, scope: %w[email profile] }
  Devise::Mailer.default reply_to: nil
  Devise::Mailer.default from: '"TEST" <[e-mail]>'
  config.confirm_within = 1.day
end

一行追加、それだけ。。。
