[Mailman-Users] mail domain constraints on membership and posting

[Richard Barrett]

I'm bringing up Mailman to take over from a mixture of older home 
brewed programs and majordomo.

I'm considering developing some "enhancements" to Mailman which I'll 
describe below because I cannot see how to achieve some of our 
objectives using current Mailman facilities. But I could be wrong so 
if anyone can tell me how to avoid doing the development I would 
appreciate hearing from you.

Take the following scenarios:

1. Mail lists where people with e-mail addresses in certain mail 
domains (typically inside our business) are free to subscribe without 
approval, where users outside these domains but inside specific other 
domains have to be approved, and all other subscription attempts are 
rejected.

2. Mail lists with members from both inside and outside our local 
mail domain, where posts from e-mail addresses inside our local mail 
domain have to be approved but posts from outside it do not.

I have it in mind that a tidy solution to such scenarios is for mail 
lists to have some extra attributes which are lists of mail domains 
and for some of the list configuration privacy options to be expanded 
to take account of these mail domain attributes.
