If you are saying that people who are members of more than one list receive a copy from each list of which they are a member when a post is sent to multiple lists, that's the way Mailman works. I.e. If I am a member of list1, list2 and list3 and someone posts to all three lists, I will receive a copy from each list. The list member setting "Avoid duplicate copies of messages?" (nodupes) does not affect this. It only affects whether I receive a list copy if I am also a To: or Cc: addressee of the post. The list's Non-digest options -> regular_exclude_lists can modify this behavior somewhat. E.g., if the regular_exclude_lists setting for li...@example.com includes li...@example.com and li...@example.com and the regular_exclude_lists setting for li...@example.com includes li...@example.com, then a member of all three lists will receive a copy of a post sent to all three lists from only li...@example.com. regular_exclude_lists need to be set up with care. In particular, if li...@example.com is in li...@example.com's regular_exclude_lists, li...@example.com MUST not be in li...@example.com's regular_exclude_lists or a post sent to both lists will not be received by anyone who is a member of both lists. Note that in the above, member means non-digest member. Digest members are not affected by this. -- Mark Sapiro <m...@msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
