Redmine

Hi to all:

Good Day. I am trying to test and setup a redmine.
I was able to install it via the bitnami installer.
Everything went fine except for the e-mail notification configuration.

During the installation in the bitnami, I tried to configure the smtp setting by providing the smtp server, username, domain, etc. However, i am still unable to send test e-mail in the Administration --> Setting --> Email Notification --> send a test e-mail.

Error is: An error occurred while sending mail (504 5.7.4 Unrecognized authentication type )

Here is what's on my email.yml file:

production:
delivery_method: :smtp
smtp_settings:
address: 10.153.215.6
port: 25
domain: ph.sc-sanyo.com
authentication: :login
user_name: jeffrey_asuncion@ph.sc-sanyo.com
password: openme

development:
delivery_method: :smtp
smtp_settings:
address: OurSMTPserver(i put it an IP Address value here)
port: 25
domain: OurDomain
authentication: :login
user_name: MyUserName
password: MyPassword

Am i missing something here? Or do i need to configure other settings?
