rdeliver 0.12-2 (amd64 binary) in ubuntu trusty

A fully functioning mail filter with RubyFilter
 rdeliver is a basic mail local delivery agent (DeliveryAgent of
 RubyFilter) that can be used in place of procmail, maildrop, etc. in a
 user's .forward or .qmail file.
 .
 The user supplies a delivery script that is written in Ruby, which
 avoids the limitations of the crippled mini-languages so often used in
 other DeliveryAgent programs.
