Certaily, this is correct.  Net::POPMail objects download
the contents of the mail item on demand, using a reference
to the Net::POP3 object that they're drawn from, so fetching
the headers or body will only work while the POP3 object is
still open (in your example, inside the mailbox.start
block).  However...

I can't see anything else obviously wrong with your code.
It should look something like this:

    require 'net/pop'
    mailbox = Net::POP3::new("pop.west.cox.net")
    mailbox.start("dhtapp", "mypassword") {
        print "# of mails: ", mailbox.mails.size, "\n"
        mailbox.mails.each { |mail|
            p mail.header, "\n"
        }
    }

Does this also not work?
