- Don't create backscatter aliases for subscribe/unsubscribe/etc by default. Nearly everyone uses web based signup.
How, exactly, does one do these? In particular, how do you remove the aliases when using mm-handler to process mail from sendmail? (I'd be happy to start the wiki page once I have the information to put there.)
This cannot be done simply with the current version of mm-handler in contrib -- it requires several code changes and would affect all actions for <listname-action@lists.example.org>. That would have bad effects on VERP bounce handling, for example.
Here is an update to mm-handler which might address this adequately. I no longer use mm-handler myself (despite having written it), so I can't test this short of installing a new Mailman instance. Can someone on the list test it?

Since it's contrib and not supported, maybe it would be reasonable to put the update into the 2.1.10 release -- provided someone can declare that it works. :) Otherwise feel free to post it on the wiki.
