This problem could be solved by running a program to handle mailing list.
I wrote a perl-script a while back that :
- add an ID header in the mail. [eg X-mailer: linux-activist-mailing-list]
  When the script detects this in incoming mail, don't redistribute it
  and treat it as mail loop
- add a counter to limit the # of mails/day. [eg 50. Just incase
  somebody made a mistake and bypass the first loop protection
  you will have at most 50 mails]
- If nothing is wrong, deliver the mail.

This should be part of any mailing list program.
