Of course it's working, you need to check if you have SMTP installed and it might depends when do you send your's emails

Try this code:

[ec2-user@ip ~]$ irb
irb(main):001:0> require 'net/smtp'
=> true
irb(main):002:0> Net::SMTP.start('localhost') do |smtp|
irb(main):003:1* smtp.send_message 'test from ruby', 'your-email, 'your-email'
irb(main):004:1> end

For mine (@gmail) it's working
