I'm trying to send a BCC email in Ruby like this:

require 'net/smtp'

smtp = Net::SMTP.new('mail.csolutions.net')
smtp.start
smtp.ready('carlyoungblood / email.com', 'carlyoungblood / bigfoot.com') do |a|
 a.write "To: Carl Youngblood <carlyoungblood / bigfoot.com>\r\n"
 a.write "From: Carl Youngblood <carlyoungblood / email.com>\r\n"
 a.write "BCC: Carl Youngblood <cyoungblood / csolutions.net>\r\n"
 a.write "Subject: Testing\r\n"
 a.write "\r\n"
 a.write "This is a test"
end

The email works, but I never get the BCC.  Any ideas as to what's wrong?

Thanks,
Carl Youngblood
