ciao a tutti,
vorrei capire, se con mailman si possono attivare topics come descritto sotto:

"A list can be configured to have message topics. Users can subscribe to these message topics in order to receive a subset of distributed messages: A message can have one or more topics and list members will receive only messages that have been tagged with a topic they are subscribed to. A message can be tagged automatically, by the message sender or by the list moderator."
