I see a pattern now, when duplicates occur and it may have to do with
mailman.
If someone in a list send an email to two or three lists on the same

Any glue what the root cause could be?
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.
Dear Mark,
in addition to my former post, where do I find information about how
mailman is handing over to postfix. Mayby that could help me.
