Answer 1

First of all as per the screenshot

I think you are using gmail as a provider.

Please go to enviroments file( development.rb or production.rb ). I guess you are using development environment.

Go to the file config/environments/development.rb

config.action_mailer.default_url_options = { :host => "my.website.com" }
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 587,
    domain:               'website.com',
    user_name:            'user@website.com',
    password:             'password',
    authentication:       'plain',
    enable_starttls_auto: true
}

Please refer ThisDoc .

hope it might help you

Answer 2

I am not using Devise but had the same error when trying to Dynamically change the smtp_settings of my application mailer. In my case the settings came from the database. The way I made it work is by using after_action callback of ActionMailer . And to merge the settings for the delivery method of my mail

Here is an example:

after_action do
 self.delivery_method = SETTING_FROM_DB.delivery_method
 settings = {
   address: SETTING_FROM_DB.address,
   port: SETTING_FROM_DB.port
   # More setting if needed
   }
 self.mail.delivery_method.settings.merge! settings
end
