This is true.

Correct on all three accounts. This is how I get around these issues:

foreach name (`cat /opt/depot/mailman/announce.src`)
  /opt/depot/mailman/bin/list_members $name >> /etc/mailman.announce
sort -iu -o /etc/mailman.announce /etc/mailman.announce
/opt/depot/mailman/bin/sync_members -w=n -d=n -a=n -f /etc/mailman.announce umbrella_list >& /dev/null

This allows me to keep a list of sub-lists - one per line in the file
/opt/depot/mailman/announce.src - and to sync them up to the umbrella list.
This umbrella list does not allow anyone to subscribe to it and all
posts to it are moderated.

I don't delete the master file /etc/mailman.announce so that I can look
through it if needed.
