The mailing list for listmasters using Sympa

[Olivier Salaün - CRU <address@concealed>]

You should set the user_data_source to 'include2' instead because it 
does a muche better management of the member cache and additionaly 
allows to mix included members and subscribed members.

With include2, the list of members is updated regularly by the 
task_manager.pl process (default TTL is 3600 sec).
