The mailing list for listmasters using Sympa

[Oliver Kiddle <address@concealed>]

Is it possible to setup nested lists with sympa. With an existing ezmlm
setup for an open source project, we have separate -announce, -users
and -workers lists. People only need to subscribe to one of the three
lists. If they subscribe to -users, they'll receive all announcements
and subscribers to -workers receive all the -users messages.

Is this possible to setup with sympa? It would be preferable that all
List-Id headers correspond to the actual list to which a message was
posted. More importantly, the X-Sequence header should be right for the
list to which a message was posted. So I'm not really interested in a
rudimentary hack like subscribing the address for the -workers list to
-users. I think Mailman calls this feature umbrella lists.

Thanks
