The express way to send mail from Ruby. Send email in one command: Pony.mail(:to => 'someone@example.com', :body => 'hello') Pony uses /usr/sbin/sendmail to send mail if it is available, otherwise it uses SMTP to localhost. Also, you may need rubygem-smtp_tls if you want to send via tls/ssl and are using ruby < 1.8.7
