The mailing list for listmasters using Sympa

["Gavin Younger" <address@concealed>]

Hello,

We have a requirement for to be able to create mailing lists "on the
fly" for one-time mailshots. The idea being that a user would be able to
specify a list of addresses to populate the list from a database (or
other source) - the system would then create a mailing list with some
unique name 
(eg address@concealed), when the mailshot is done it
would then remove the list. 

I seem to remember some discussion about this being done with families a
while back, but cannot seem to find a reference...can anyone on the list
point me in the right direction?

Regards,
