It's better than > /dev/null :-). Let's face it - if you're going to publish 
an admin address to help the lowest common denominator of netizen, then you 
can't munge it, so it will get spam. Mailman doesn't provide filtering for 
email accounts, nor should it. So the best you can do is advise admins of
good filtering software, and best practice ways of using it. Droping html 
mail happens to be one practice that works pretty well for a given type of 
list membership.

It doesn't. But you can put all the requests from list members into another 
folder, or give them a higher priority. It all helps. If you need to 
prioritize subscription problems then you could use a feedback form, and maybe
Mailman should provide one.

I never understood why mailman wasn't changed to allow users to change there 
own addresses years ago. Being able to add valid receiving addresses would 
help, too. That is also something mailman can help with.
