What you are saying is technically correct. But there is a caveat. I
am subscribed to about two dozens list (more ? I lost count), and the
only one I am getting spam from is info-cyrus. It's also the only one
that I aware permit posting by non-subscriber. So there is a
correllation, but are there a causation ? I do not know, it might be a
coincidence. But it's one heck of a coincidence.
Also, I do believe that list administrator have a responsability to take
measure against abuse of their list. Acting as amplificator for spammer
certainly constitute an abuse. I admin a few low-volume myself, and I
take spam very seriously. The only list where I permit posting by
non-subscribers is moderated. While my list do not have the volume or
notoriety of info-cyrus, I can't remember the last time a spam got
through one my list.
If forged sender address ever become a problem, I will run my lists
through SpamAssassin and moderate high-scoring mail by hand. Simple
matter of responsability to my users.
