Help: Why is mailer.rb in app/models

I got errors trying to get Redmine to send emails. The error looks like this: "Error: Email delivery error: No connection could be made because the target machine actively refused it. - connect(2)".

I went to Redmine guide and Rails guide action mailer basics. And got myself a question:

Why is mailer.rb in redmine/app/models while Rails Guide suggests mailer.rb in app/mailers?

$ bin/rails generate mailer UserMailer
create  app/mailers/user_mailer.rb
invoke  erb
create    app/views/user_mailer
invoke  test_unit
create    test/mailers/user_mailer_test.rb

Is there any document in Redmine about Mailer?
Thanks.

I found the answer that the home of action Mailer (hence mailer.rb) has changed as Rails version changes.
In Rails Guides 2.3.11, action mailer resides in app/models.
While in Current Rails Guides 4.1.7, action mailer has its own home at app/mailers.

I still have problems sending emails in Redmine, eliminating the conflict in redmine guides and rails guides gives me a comfort to proceed.

Hello Kuolai,

The error message seems to point to a bad configuration (such as wrong host/port or firewall blocking).
I suggest you:

Double check your configuration.yml, take note that the configuration is per environment
Double check which environment your Redmine instance is using. (In Administration/information)

In case it could be a firewall configuration problem, you could test making the connection from your Redmine server to the SMTP server using telnet.
If that doesn't allow you to discover a faulty configuration, you could also try a tcpdump to make sure of what connection is attempted (and refused) by Redmine to the SMTP server.

Cheers,

Hi Martin,

Thanks for offering a help. Even I did not state clear error messages, you have pointed me to a few possible directions: configuration, environment, and SMTP server.

I checked and they seemed ok to me. And I am using gmail smtp server with my own gmail account under development mode.

Never mind. I found the solution and it is a stupid one.

In config/configuration.yml
...
user_name: "me@gmail"
...

should be
user_name: "me@gmail。com"

My bad.
Thanks for your support and it gets me going.
