These issues are mostly larger than Mailman and more SMTP related than 
any thing else.  As such, traditional SMTP anti-spam solutions are 
probably the best fix here.

The first things that come to mind are

  - SPF
  - Domain Keys
  - Something like Sendmail's "protected recipients" or comparable.

I don't think that Mailman currently does this, but I'm betting that 
others can come up with a way to make it do it.
