Besides what Mark says, it looks to me like you're describing a customer
relations application.  "Mailman Banzai!" and all that, but Mailman is not
designed as a CRM, and hard to tune to be one.

If a CRM is what you want, I'm sure there are dedicated applications with
more of the features you need.  I'm sorry I don't have any concrete
suggestions, I don't use or need CRMs.
