An Umbrella List is a list of other lists.<br>
For example, you have the following lists running in Mailman:<br>
ThreeBlindMice: Minnie@farm.org, Mighty@cartoon.net, Mickey@disney.com<br>
ThreeBears: Smokey@usda.gov, Little@pbs.org, Momma@mgoose.net<br>
ThreeMenNaTub: Rub@tub.org, Dub@tub.org, Little@pbs.org<br>
<br>
You can create an Umbrella List called, "Threesomes" and instead of people,<br>
it will contain the above list names. When you send email to Threesomes, it<br>
goes to each of the individual lists...<br>
Threesomes: ThreeBlindMice@mylists.com, ThreeBears@mylists.com,<br>
ThreeMenNaTub@mylists.com<br>
<br>
When mailman sends out a monthly password reminder, it sends an email to<br>
every person in its lists. If it did that for the Umbrella List<br>
"Threesomes", then it would treat "ThreeBlindMice" as an ordinary user.<br>
Mailman would send an email to "ThreeBlindMice" that contained the password<br>
for subscribing or unsubscribing it to the list "ThreeSomes". Everyone on<br>
the "ThreeBlindMice" list would receive that message with the password. Now<br>
that is fine in the case of Minnie and Mighty, but Mickey has been known to<br>
do a few silly things in his time...<br>
<br>
You can keep Mickey from getting the password by telling Mailman to send<br>
this type of information to "ThreeBlindMice-owner" instead of to<br>
"ThreeBlindMice".<br>
<br>
By making "Threesomes" into an Umbrella List, you can tell Mailman to add<br>
"-owner" to any notices, confirmations and passwords that it sends out to<br>
list members.<br>
<br>
Personally, I would like to see Umbrella Lists do more than just that. IMO,<br>
they should only send one message out to each actual user, regardless of how<br>
many lists that user is on. Currently, if a user is on multiple lists that<br>
are under one Umbrella list, then that user will receive multiple mailings<br>
from one message sent to the Umbrella list. In the example above,<br>
Little@pbs.org would receive two messages everytime someone sent an email to<br>
"Threesomes".<br>
<br>
BTW: there is a work around for that using a script and a cron job to create<br>
a separate mass list - but that's not pretty.<br>
