Redmine

Hi,

We are using redmine-1.1.0. We want to set email notifications in the redmine.

We tried the following options in email.yml

production:
delivery_method: :smtp
smtp_settings:
tls: true
address: lvmail01.livialegal.com
port: 25
domain: lvmail01.livialegal.com
authentication: :plain
user_name: username
password: password

After the above configuration we restarted the redmine service and tried to send the email notifications but we get the following error.

An error occurred while sending mail (503 5.5.1 Error: authentication not enabled )

Please let us know how can we resolve this issue. Quick help is appreciated as it is of high priority
