Read an email from standard input.

General options:
  unknown_user=ACTION      how to handle emails from an unknown user
                           ACTION can be one of the following values:
                           ignore: email is ignored (default)
                           accept: accept as anonymous user
                           create: create a user account
  no_permission_check=1    disable permission checking when receiving
                           the email

Issue attributes control options:
  project=PROJECT          identifier of the target project
  status=STATUS            name of the target status
  tracker=TRACKER          name of the target tracker
  category=CATEGORY        name of the target category
  priority=PRIORITY        name of the target priority
  allow_override=ATTRS     allow email content to override attributes
                           specified by previous options
                           ATTRS is a comma separated list of attributes

If you want to set default values for custom fields, set the value similar to
the attributes above, using the name of the custom field as a key.
Custom ields set this way can only contain characters valid for environment
variables, i.e. no punctuation and no whitespace.
Additionally, you need to set the list of the attributes set this way in the
default_attributes list like this:

  default_attributes="CustomField1 CustomField2"

Examples:
  # No project specified. Emails MUST contain the 'Project' keyword:
  rake redmine:email:read RAILS_ENV="production" < raw_email

  # Fixed project and default tracker specified, but emails can override
  # both tracker and priority attributes:
  rake redmine:email:read RAILS_ENV="production" \\
                  project=foo \\
                  tracker=bug \\
                  allow_override=tracker,priority < raw_email
END_DESC

    task :read => :environment do
      options = { :issue => {} }
      default_fields = (ENV['default_fields'] || "").split
      default_fields |= %w[project status tracker category priority fixed_version]
      default_fields.each{ |field| options[:issue][field] = ENV[field] if ENV[field] }

      options[:allow_override] = ENV['allow_override'] if ENV['allow_override']
      options[:unknown_user] = ENV['unknown_user'] if ENV['unknown_user']
      options[:no_permission_check] = ENV['no_permission_check'] if ENV['no_permission_check']

      MailHandler.receive(STDIN.read, options)
