I thought I'd already covered this, but:

1. We're talking about majordomo, not resend, although loop prevention
   makes some sense to both.  Fortunately resend already has taboo_* which
   majordomo doesn't.

2. It's hard to do this without limiting proper use.  I suspect that my
   frequent messages to majordomo-users would get flagged as a loop.
   Extending thins to have a list of addresses which aren't flagged as
   loops just bloats the whole thing even more.  A simple n messages per
   day or 1 message per n minutes is simply not good enough.

3. Storing and checking state is expensive.  Think of large lists with lots
   of contributors.  Now you have to a bunch of extra file operations for
   every message.  People already say that Majordomo has too much overhead.

This is a tough problem.  Try to think about the boundary cases, not just
small lists with few subscribers and low traffic.
