How to configure email notifications in Redmine?

I have installed Redmine in offline mode by using Bitnami and configured email notifications as follows, as says in Redmine: Email Configuration

My environment:

Environment:
    Redmine version     2.3.2.stable
    Ruby version        1.9.3-p231 (2012-05-25) [i386-mingw32]
    Rails version       3.2.13
    Environment         production
    Database adapter    Mysql2
    Redmine plugins:    no plugin installed

Part of configuration.yml:

# default configuration options for all environments
default:
  # Outgoing emails configuration (see examples above)
  email_delivery:
    delivery_method: :smtp
    smtp_settings:    
      address: ...here smtp.domain or ip of smtp- server...
      port: 25
      domain: ...some domain...
      authentication: :login
      user_name: ...name@domain...
      password: "..."

In the same domain runs the mail server.

I requested my password from Redmine UI:

However, the message does not come.

What I have in production.log:

When I tested this configuration outside the intranet, I used the gmail. Part of configuration.yml:

# default configuration options for all environments
default:
  # Outgoing emails configuration (see examples above)
  email_delivery:
    delivery_method: :smtp
    smtp_settings:    
      address: smtp.gmail.com
      port: 587
      domain: gmail.com
      authentication: :login
      user_name: ...name@gmail.com
      password: "..."

When I requested the password in this configuration, the message has come.

message:

To change the password, click on the following link:
http://localhost:3000/account/lost_password?token=dd36a006157cfa8d208ba11822c9283f14ef5f65

You have received this notification because you have either subscribed to it, or are involved in it.
To change your notification preferences, please click here: http://hostname/my/account

What I see in production.log now:

Started POST "/redmine/account/lost_password" for 127.0.0.1 at 2013-08-22 22:09:40 +0400
Processing by AccountController#lost_password as HTML

So,

• If I use gmail, the message are sent and delivered

• If I use other, the message are not sent or sent but not delivered
