Redmine

I upgraded from 1.4 to 2.1.4-stable and mail notifications stopped working.

I made modification to configuration.yml and changed "smtp_settings" to "async_smtp_settings" but it did not help.

configuration.yml

default:
  email_delivery:
    delivery_method: :async_smtp
    async_smtp_settings:
      address: ares.gi-bon.local
      port: 25
      domain: gi-bon.sk

production:

development:

Log does not contain any error message and test mail is not delivered (even not sent).
