Answer 1

See http://railscasts.com/episodes/206-action-mailer-in-rails-3

def registration_confirmation(user) @user = user attachments["rails.png"] = File.read("#{Rails.root}/public/images/rails.png") mail(:to => "#{user.name} <#{user.email}>", :subject => "Registered") end 

Answer 2

You must use the Action Mailer built into Rails, which supports sending emails with attachments.

For Rails 3.x - http://guides.rubyonrails.org/action_mailer_basics.html#sending-emails-with-attachments

For Rails 2.3.8+ - http://guides.rubyonrails.org/v2.3.8/action_mailer_basics.html#sending-multipart-emails-with-attachments

Answer 3

For an alternative consideration, I had good experience using Pony for email. This happens to have many dependencies on gems, but it’s very nice to work with them. See README for more information.
