Redmine

Hi,

settings like this work when the server is connected to internet by means of a transparent proxy, hence through its gateway:

default:
  email_delivery:
    delivery_method: :smtp
    smtp_settings:
      #tls: true
      enable_starttls_auto: true
      openssl_verify_mode: none
      address: "smtp.office365.com" 
      port: 587
      domain: "smtp.office365.com" 
      authentication: plain
      user_name: "redmine@mycompany.com" 
      password: "thepassword" 

But they don't seem to work when the server is connected to internet using a proxy, how can I tell redmine that it has to go through a proxy to reach office365 smtp service?

thanks
