Good morning/Afternoon/evening, I've been looking for a possible solution now for a few days, checked the docs, archives, search engines, etc. No clue.
We maintain several large mail lists for a client, excess of 40k subscribers, all opt-in - verified - signed in blood addresses. We use verp to purge the list of mis behaving subscribers. People who use the AOL spam button to unsubscribe and their ilk. No issues there, all is working fine. The client is asking for the ability to manage list messages in a new way. We are unable to do so using our current software, ezmlm. Here is the scoop. The client has twenty mail lists, and subscribers can sign up for any number of lists. The client wants to be able to send a common message to some lists without sending duplicate messages if a subscriber is on more then one list. The key is some lists must be excluded from receiving the message. Think distributors vs retailers vs wholesales vs consumers. This brought us to looking at Mailman topics. As we understand it you can have topics, and subscribers will only receive messages directed at the topics they subscribe to. This means a subscriber could subscribe to [members], [stores], and [retailers], if we send a message to [stores] they will receive it. If we send a message to all topics, subscribers will receive only one message. This is what we want. However, if we send a message only to [stores] and to [members], subscribers will receive two copies. This is not what we want. In order to have a subscriber receive only one copy of the message, the message must go to ALL topics, [stores], [members], [retailers], [malls], [gas_stations], [gas_stations_with_inside_bathrooms], [gas_stations_with_outside_bathrooms_in_north_dakota], etc. Not what we want. Is this correct? Can we send a message to only three of twenty topics and subscribers who are only subscribed to one of the seventeen excluded topics will receive no message, and subscribers subscribed to two of the three included topics will receive only one message? It is not clear to us from the docs or from any information we have been able to find. Thanks, DAve -- Three years now I've asked Google why they don't have a logo change for Memorial Day. Why do they choose to do logos for other non-international holidays, but nothing for Veterans? Maybe they forgot who made that choice possible. ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
