A solution for: An error occurred while sending mail (SSL_connect returned=1 errno=0 state=unknown state: unknown protocol) in Redmine 2.0 / Rails 3.2.3
Being a Drupal developer I do use magnificent redmine (http://redmine.org) to manage my tasks and projects. If you don't know, Redmine is a Rails-based application so from time to time I have my hands dirty with ruby code (it doesn't hurt at all ;)).
