I've no idea but if you are right then anyone could send email (and spam) 
to a closed mailing list by faking his sender address. And this does not 
happen, or happens rarely ime. I do not know to what lengths the list 
software goes to check the sender. It might check the From headers to see 
the right domain as origin or something like that. Of course one could 
fake that too with the right information. F.ex. the mailing list software 
clips off all incoming From headers so the real origin of mail (or spam) 
cannot be found, except by examining list software logs, which are 
probably not read by anyone because it's a boring and unrewarding task.
