Untauthenticated SMTP fails "No SMTP username provided"

[kaffe19]

🐛 Bug Report

🔬 How To Reproduce

Steps to reproduce the behavior:

1. pull pglombardo/pwpush:latest

2. set PWPMAILSMTP_ENABLE_STARTTLS_AUTO -> false

3. do not set PWPMAILSMTP_AUTHENTICATION, PWPMAILSMTP_USER_NAME or PWPMAILSMTP_PASSWORD (exactly as when it was working before)

4. send test mail from console: password-pusher(prod)> TestMailer.send_test_email("abc@cde.ef").deliver_now

--> Configured FROM: address: 'abc@abc.abc' app/mailers/test_mailer.rb:7:in `send_test_email': No SMTP username provided: smtp_user_name (StandardError)

SMTPsettings:

password-pusher(prod)> Rails.application.config.action_mailer.smtp_settings => {:address=>"mysmtpserver.example.com", :port=>25, :open_timeout=>10, :read_timeout=>10, :enable_starttls_auto=>false}
