The mailing list for listmasters using Sympa

[Olivier Salaün <address@concealed>]

We've had requests for this feature for quite a long time but did not 
implement it because there were details to sort :

   * a message distributed via 2 lists might change on the way (custom
     subject, footer,...). If the 'no_duplicate' mode is used, how
     could decide which message should be sent ? First in wins ?
   * How about users that have filters/triggers configured in their
     mail client. Eg: I am subscribed to both important-list and
     less-important-list. I carefully check all messages that were
     received through important-list, but one day a message is sent to
     both ; I only it through my less-important-list subscription. I
     miss this important message...

Thomas, could you describe how the feature is implemented in Lyris ? How 
do they cope with this problem ? Is it a global parameter or something 
per list ? per group of lists ?
