It's because of the double newlines: you are adding \n as well as having 
the newline because the string is broken onto another line.

You can see this in irb:

>> msg = "From: nobody@localhost\n
To: nobody@localhost\n\n\n
Hello world"
=> "From: nobody@localhost\n\nTo: nobody@localhost\n\n\n\nHello world"

Personally I'd use a heredoc:

require 'net/smtp'

module Sendemail

  def send_email(from, to, subject, message) # edited

    msg = <<EOM
From: #{from}
To: #{to}
Subject: #{subject}
Date: #{Time.now}

#{message}
EOM
    Net::SMTP.start('127.0.0.1',25) do |smtp|
      smtp.send_message(msg, from, to)
    end

  end
  module_function :send_email

end

Sendemail.send_email("nobody@localhost","candlerb@localhost","Test 
message", "hello world!")
