Redmine

Hi,
I have:

Environment:
Redmine version 3.1.0.stable
Ruby version 2.0.0-p645 (2015-04-13) [x86_64-linux]
Rails version 4.2.3
Environment production
Database adapter Mysql2
SCM:
Git 1.7.10.4
Filesystem
Redmine plugins:
redmine_contacts 4.0.1
redmine_email_fetcher 0.3.1

Email integration is set and working, anytime an issue is updated the corresponding email notification is sent to the users involved with the issue. But that is not happening for Contacts.
This is what I have in the configuration.yml file:

production:

1. Outgoing emails configuration
2. See the examples below and the Rails guide for more configuration options:
3. http://guides.rubyonrails.org/action_mailer_basics.html#action-mailer-configuration
   email_delivery:
   delivery_method: :smtp
   smtp_settings:
   address: "localhost"
   enable_starttls_auto: true
   openssl_verify_mode: 'none'
   port: 25
   domain: "localhost"

In Settings:Email notifications I have:

Emission email address: myemail@mydomain.com
Blind carbon copy recipients (bcc): checked
Default notification options: 'For any event on all my projects'
Actions checked: Issue added, Issue Updated

I was checking the logs to see if an error message could guide me, but found none, the only reference to a email-like action was:

App 17258 stderr: Rendered mailer/_issue.text.erb (3.7ms)
App 17258 stderr: Rendered mailer/issue_edit.text.erb within layouts/mailer (4.4ms)
App 17258 stderr: Rendered mailer/_issue.html.erb (0.7ms)
App 17258 stderr: Rendered mailer/issue_edit.html.erb within layouts/mailer (1.9ms)

Can anyone help me please?? I'm a redmine newbie :(

Thanks in advance!!
