Currently Umbrella lists *do not* stop folks from receiving multiple copies. To stop folks from receiving multiple copies, you will have to make your own mega-list by using a script and building the mega-list from each of the sub lists. In the example below, we have a lot of lists for various groups working on a project called Pegasus. The pegasus-all list includes everyone on the sub lists (and only one copy of each email address). === === #!/bin/bash # Create and sync the [EMAIL PROTECTED] mailing list using Mailman # The list includes everyone on a Pegasus* mailing list. echo " " >/tmp/pegasus_list for i in `/home/mailman/bin/list_lists |grep -i pegasus |grep -vi _all| \ sed 's/^ *//' |cut -f1 "-d " ` do /home/mailman/bin/list_members $i >>/tmp/pegasus_list done cat /tmp/pegasus_list |sort -u >/tmp/pegasus_all_list /home/mailman/bin/sync_members -f /tmp/pegasus_all_list pegasus_all >/dev/null rm /tmp/pegasus_list rm /tmp/pegasus_all_list === === The script dumps out the name of each list using "list_lists", It looks for any list with "pegasus" in the name, dumps the users out of those lists into a file using "list_members", finally it uses "sync_members" to pump the users into the pegasus_all list. I do a lot of superfluous stuff in the example (like sort the list for unique members), that Mailman will actually handle automatically. I wrote this when I was still just learning what Mailman could do. This script is kicked off by crontab hourly so the pegaus_all list is always fairly up to date. I hope this helps.
