Redmine

Definitely runs only once, but sends out 4 emails each time it runs.

same effect on Windows Server and Redmine 1.4.0

D:\redmine\apps\redmine\htdocs>rake redmine:send_reminders days=1 users="3" RAILS_ENV="production" --trace
Please install RDoc 2.4.2+ to generate documentation.
** Invoke redmine:send_reminders (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute redmine:send_reminders

-> sends 3x Mails with same value

Can´t see why. Seems all alright in mailer.rb:

 # Sends reminders to issue assignees
  # Available options:
  # * :days     => how many days in the future to remind about (defaults to 7)
  # * :tracker  => id of tracker for filtering issues (defaults to all trackers)
  # * :project  => id or identifier of project to process (defaults to all projects)
  # * :users    => array of user ids who should be reminded
  def self.reminders(options={})
    days = options[:days] || 7
    project = options[:project] ? Project.find(options[:project]) : nil
    tracker = options[:tracker] ? Tracker.find(options[:tracker]) : nil
    user_ids = options[:users]

    scope = Issue.open.scoped(:conditions => ["#{Issue.table_name}.assigned_to_id IS NOT NULL" +
      " AND #{Project.table_name}.status = #{Project::STATUS_ACTIVE}" +
      " AND #{Issue.table_name}.due_date = ?", days.day.from_now.to_date]
    )
    scope = scope.scoped(:conditions => {:assigned_to_id => user_ids}) if user_ids.present?
    scope = scope.scoped(:conditions => {:project_id => project.id}) if project
    scope = scope.scoped(:conditions => {:tracker_id => tracker.id}) if tracker

    issues_by_assignee = scope.all(:include => [:status, :assigned_to, :project, :tracker]).group_by(&:assigned_to)
    issues_by_assignee.each do |assignee, issues|
      deliver_reminder(assignee, issues, days) if assignee.is_a?(User) && assignee.active?
    end
  end

btw: SMTP Server is in local network (tried exchange server and hamster )
