LinuxQuestions.org - 454 4.7.0 TLS not available due to local problem

Hello,

I am unable to send mail through Redmine settings > Outgoing email address. I am able to get this command working:

#echo "hello" | mail -s hi accounts@brand.net

I setup redmine on CentOS 6.5. My /var/www/redmine/config/configuration.yaml looks like:

Code:

production:

  email_delivery:

    delivery_method: :smtp

    smtp_settings:

    address: "brand.net"

    port: 25

    domain: "brand.net"

    authentication: :login

    user_name: "mo@brand.net"

    password: 'mypassword'

    openssl_verify_mode: 'none'

While I browse to Redmine > Settings > Email notifications > Send a test mail. It throws the error:

Code:

An error occurred while sending mail (454 4.7.0 TLS not available due to local problem )

I followed https://www.linode.com/docs/email/po...x-smtp-debian7 guide on my machine( debian config is very similar to CentOS for postfix). I am not using any relay server but just own smtp server.

My maillog says:
