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.
