I can't say if it's doable or not, but using TMDA to challenge posts
from non-subscribers seems almost ideal for preventing this.

For anyone not familiar with TMDA, it's a mail filtering tool that will
send a simple challenge back to the sender (ie. "Hi, I'm TMDA, please
respond to this to ensure you're a real person who wished to post to the
DragonFly kernel list"), and also provides whitelisting (so not everyone
needs to be challenged).  It has more features, but that pretty much
sums up how it would be useful to keep spam off of a mailing list. 
http://tmda.net is their home page.
