The problem was that the mailer sent a message from an account that does not exist, created a new account and added an appropriate one to the config, and everything went well.

    If I remember correctly (I remember very vaguely), then during initialization, the application saves its copy of smtp_settings and changing them for ActionMailer::Base becomes just pointless. In the logs, it is clear that an attempt was made to send a letter and the letter fell into the console (default behavior for the development environment) It would be more correct to specify the settings for a specific environment in the files config/environments/*.rb because in a test environment, using a mailer is clearly redundant. However, if, after all, you need to set parameters for all environments, then it is better to do this in config/application.eb :

     class Application < Rails::Application #... config.action_mailer.smtp_settings = { #твои настройки } end

    By the way, (again, if I remember correctly) config/environments/*.rb priority than what is specified in config/application.eb . So, at least for the test, it is possible to return the default behavior.
