Distribution lists : list of lists

[Michael Harlaut]

Hi,

I had no answer about the best way to create a distribution list which 
delivers in shared folders, so I found a new question :)

Is it possible to create lists of lists ?

For exemple :

list1 : user1 at domain.tld, user2 at domain.tld
list2 : user3 at domain.tld, user4 at domain.tld

list3: list1 at domain.tld, list2 at domain.tld

It can be interesting to manage large groups (and lists) of users.

Thanks,
