I successfully added the actionmailer to my project, so in my development stage My mails are rendering normal if I tried to use LETTER OPENER delivery method but once I switched to smtp I keep getting that error (Net::SMTPServerBusy in Devise::PasswordsController#create in Rails 7. (421 Server busy, too many connections) but the token with link is rendering on my terminal or console
421 Server busy, too many connections Extracted source (around line #1059): def check_response(res) unless res.success? raise res.exception_class.new(res) end end
this is my action mailer configuration

`
Rails.application.configure do

Settings specified here will take precedence over those in config/application.rb.

config.action_mailer.default_url_options = { :host => 'localhost:3000' }
#config.action_mailer.delivery_method = :letter_opener
config.action_mailer.perform_deliveries = true
config.action_mailer.delivery_method = :smtp

config.action_mailer.smtp_settings = {
address: 'smtp.gmail.com',
port: 587,
domain: 'localhost:3000',
user_name: '[email protected]',
password: 'xxxxxxxxx',
authentication: 'plain',
enable_starttls_auto: true,
open_timeout: 5,
read_timeout: 5 }

config.action_mailer.raise_delivery_errors = true
`
Note: I used the google mail App password to generate password for the smtp mailer then used my mail as password

Errors from my terminal ;
