Looking for email address managemet plugin

HI,

My site is a membership site for my son’s Cub-Scout pack. I’m hosted on BlueHost that uses cPanel.

The “Officers” of the packe (Committee, Den Leaders etc) each have an e-mail address in my domain that they can access through webmail (Squirrel Mail).

What I want to do is to auto-generate some distributions lists for them in their address books based on the WordPress Site membership.

The idea is that I would centrally manage (well, WordPress would!) distros for the committe, each Den, the whole pack and so on.

I am managing the membership of each of those groups using a plugin and Theme I have written, but I don’t know whow to interface with the address book.

Are there any Plugins out there that I could look at?

Thanks!
