Answer 1

# ActionMailer Config in development/production rb file 
config.action_mailer.default_url_options = { :host => 'localhost:3000' } 
config.action_mailer.delivery_method = :smtp 
# change to true to allow email to be sent during development 
config.action_mailer.perform_deliveries = true 
config.action_mailer.raise_delivery_errors = true 

config.action_mailer.smtp_settings = { 
    address: "smtp.gmail.com", 
    port: 587, 
    domain: "mail.google.com",####important 
    authentication: "plain", 
    enable_starttls_auto: true, 
    user_name: ENV["GMAIL_USERNAME"], 
    password: ENV["GMAIL_PASSWORD"] 
} 

和

config/initializers/devise.rb 

config.mailer_sender = 'email@example.com'
