In short, no.  You cannot defend easily against gratuitously broken 
software.  I would personally see if there was an identifying mark in 
the headers for the mailer that guy was using and use that as a 
selector to catch incoming mail to the list.  I'd also probably just 
block the whole originating domain of that guy in my MTA, but I have a 
nasty inclination.

Maybe we should attempt to detect an unusual rate of posting from an 
address and start holding mail from them - this is fraught with 
problems and is bound to not work when it matters.  Can anyone suggest 
an algorithm that might have a chance of detecting stuff - there is 
some rate detection in the bounce handlers I believe.
